Changing a host architecture or a CPU is not as easy as assigning a new
value to the appropriate element in virCaps since there is a relation
between the CPU and host architecture (we don't really want to test
anything on an AArch64 host with core2duo CPU). This patch introduces
qemuTestSetHostArch and qemuTestSetHostCPU helpers which will make sure
the host architecture matches the host CPU.

Commit 8563560026 switched from
hardcoded use of strcontent to hardcoded use of fixedcontent
(fixedcontent is *sometimes* a copy of strcontent with a \n
appended). This was a problem because sometimes fixedcontent is *not*
a copy of strcontent, but is instead NULL, leading to the regenerated
test case output being a 0 length file.
This patch creates a new const char *cmpcontent initialized to
strcontent, but changed to fixedcontent if/when fixedcontent is
created, then always uses cmpcontent instead of (str|fixed)content.
Most of QEMU's PCI display device models, such as:
libvirt video/model/@type QEMU -device
------------------------- ------------
cirrus cirrus-vga
vga VGA
qxl qxl-vga
virtio virtio-vga
come with a linear framebuffer (sometimes called "VGA compatibility
framebuffer"). This linear framebuffer lives in one of the PCI device's
MMIO BARs, and allows guest code (primarily: firmware drivers, and
non-accelerated OS drivers) to display graphics with direct memory access.
Due to architectural reasons on aarch64/KVM hosts, this kind of
framebuffer doesn't / can't work in
qemu-system-(arm|aarch64) -M virt
machines. Cache coherency issues guarantee a corrupted / unusable display.
The problem has been researched by several people, including kvm-arm
maintainers, and it's been decided that the best way (practically the only
way) to have boot time graphics for such guests is to consolidate on
QEMU's "virtio-gpu-pci" device.
>From <https://bugzilla.redhat.com/show_bug.cgi?id=1195176>, libvirt
supports
<devices>
<video>
<model type='virtio'/>
</video>
</devices>
but libvirt unconditionally maps @type='virtio' to QEMU's "virtio-vga"
device model. (See the qemuBuildDeviceVideoStr() function and the
"qemuDeviceVideo" enum impl.)
According to the above, this is not right for the "virt" machine type; the
qemu-system-(arm|aarch64) binaries don't even recognize the "virtio-vga"
device model (justifiedly). Whereas "virtio-gpu-pci", which is a pure
virtio device without a compatibility framebuffer, is available, and works
fine.
(The ArmVirtQemu ("AAVMF") platform of edk2 -- that is, the UEFI firmware
for "virt" -- supports "virtio-gpu-pci", as of upstream commit
3ef3209d3028. See
<https://tianocore.acgmultimedia.com/show_bug.cgi?id=66>.)
Override the default mapping of "virtio", from "virtio-vga" to
"virtio-gpu-pci", if qemuDomainMachineIsVirt() evaluates to true.

The virsh-self-test script compared the test's return code with 1 and only if
the return code matched this value then the test was marked as failed. Problem
is that SIGSEGV returns 139 (or 11 to be precise, since shell reserves the MSB
for abnormal exit signaling) which passes the check just fine and test then
appears as successful which it most certainly wasn't.
Therefore, flip the logic to compare against 0 instead and every other result
will be treated as a failed test case.

Add a new secret usage type known as "tls" - it will handle adding the
secret objects for various TLS objects that need to provide some sort
of passphrase in order to access the credentials.
The format is:
<secret ephemeral='no' private='no'>
<description>Sample TLS secret</description>
<usage type='tls'>
<name>mumblyfratz</name>
</usage>
</secret>
Once defined and a passphrase set, future patches will allow the UUID
to be set in the qemu.conf file and thus used as a secret for various

We already have the ability to turn off dumping of guest
RAM via the domain XML. This is not particularly useful
though, as it is under control of the management application.
What is needed is a way for the sysadmin to turn off guest
RAM defaults globally, regardless of whether the mgmt app
provides its own way to set this in the domain XML.
So this adds a 'dump_guest_core' option in /etc/libvirt/qemu.conf
which defaults to false. ie guest RAM will never be included in
the QEMU core dumps by default. This default is different from
historical practice, but is considered to be more suitable as
a default because
a) guest RAM can be huge and so inflicts a DOS on the host
I/O subsystem when dumping core for QEMU crashes
b) guest RAM can contain alot of sensitive data belonging
to the VM owner. This should not generally be copied
around inside QEMU core dumps submitted to vendors for
debugging
c) guest RAM contents are rarely useful in diagnosing
QEMU crashes

Add support for using the new approach to hotplug vcpus using device_add
during startup of qemu to allow sparse vcpu topologies.
There are a few limitations imposed by qemu on the supported
configuration:
- vcpu0 needs to be always present and not hotpluggable
- non-hotpluggable cpus need to be ordered at the beginning
- order of the vcpus needs to be unique for every single hotpluggable
entity
Qemu also doesn't really allow to query the information necessary to
start a VM with the vcpus directly on the commandline. Fortunately they
can be hotplugged during startup.
The new hotplug code uses the following approach:
- non-hotpluggable vcpus are counted and put to the -smp option
- qemu is started
- qemu is queried for the necessary information
- the configuration is checked
- the hotpluggable vcpus are hotplugged
- vcpus are started
This patch adds a lot of checking code and enables the support to
specify the individual vcpu element with qemu.
Individual vCPU hotplug requires us to track the state of any vCPU. To
allow this add the following XML:
<domain>
...
<vcpu current='2'>3</vcpu>
<vcpus>
<vcpu id='0' enabled='yes' hotpluggable='no' order='1'/>
<vcpu id='1' enabled='yes' hotpluggable='yes' order='2'/>
<vcpu id='1' enabled='no' hotpluggable='yes'/>
</vcpus>
...
The 'enabled' attribute allows to control the state of the vcpu.
'hotpluggable' controls whether given vcpu can be hotplugged and 'order'
allows to specify the order to add the vcpus.
Power 8 platform's basic hotpluggable unit is a core rather than a
thread for x86_64 family. This introduces most of the complexity of the
matching code and thus needs to be tested.
The test data contain data captured from in-order cpu hotplug and
unplug operations.
During review it was reported that adding at least 11 vcpus creates a
collision of prefixes in the monitor matching algorithm. Add a test case
to verify that the problem won't happen.
As the combination algorithm is rather complex and ugly it's necessary
to make sure it works properly. Add test suite infrastructure for
testing it along with a basic test based on x86_64 platform.
To allow matching up the data returned by query-cpus to entries in the
query-hotpluggable-cpus reply for CPU hotplug it's necessary to extract
the QOM path as it's the only link between the two.
QEMU reports whether 'query-hotpluggable-cpus' is supported for a given
machine type. Extract and cache the information using the capability
cache.
When copying the capabilities for a new start of qemu, mask out the
presence of QEMU_CAPS_QUERY_HOTPLUGGABLE_CPUS if the machine type
doesn't support hotpluggable cpus.
Prepare to extract more data by returning an array of structs rather than
just an array of thread ids. Additionally report fatal errors separately
from qemu not being able to produce data.
Turn various vshPrint() informative messages into vshPrintExtra(), so
they are not printed when requesting the quiet mode; neither XML/info
outputs nor the results of commands are affected.
Also change the expected outputs of the virsh-undefine test, since virsh
is invoked in quiet mode there.
Some informative messages might still be converted (and thus silenced
when in quiet mode), but this is an improvements nonetheless.

For some unknown reason the original implementation of the <forwarder>
element only took advantage of part of the functionality in the
dnsmasq feature it exposes - it allowed specifying the ip address of a
DNS server which *all* DNS requests would be forwarded to, like this:
<forwarder addr='192.168.123.25'/>
This is a frontend for dnsmasq's "server" option, which also allows
you to specify a domain that must be matched in order for a request to
be forwarded to a particular server. This patch adds support for
specifying the domain. For example:
<forwarder domain='example.com' addr='192.168.1.1'/>
<forwarder domain='www.example.com'/>
<forwarder domain='travesty.org' addr='10.0.0.1'/>
would forward requests for bob.example.com, ftp.example.com and
joe.corp.example.com all to the DNS server at 192.168.1.1, but would
forward requests for travesty.org and www.travesty.org to
10.0.0.1. And due to the second line, requests for www.example.com,
and odd.www.example.com would be resolved by the libvirt network's own
DNS server (i.e. thery wouldn't be immediately forwarded) even though
they also match 'example.com' - the match is given to the entry with
the longest matching domain. DNS requests not matching any of the
entries would be resolved by the libvirt network's own DNS server.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1331796
If you define a libvirt virtual network with one or more IP addresses,
it starts up an instance of dnsmasq. It's always been possible to
avoid dnsmasq's dhcp server (simply don't include a <dhcp> element),
but until now it wasn't possible to avoid having the DNS server
listening; even if the network has no <dns> element, it is started
using default settings.
This patch adds a new attribute to <dns>: enable='yes|no'. For
backward compatibility, it defaults to 'yes', but if you don't want a
DNS server created for the network, you can simply add:
<dns enable='no'/>
to the network configuration, and next time the network is started
there will be no dns server created (if there is dhcp configuration,
dnsmasq will be started with "port=0" which disables the DNS server;
if there is no dhcp configuration, dnsmasq won't be started at all).
The new forward mode 'open' is just like mode='route', except that no
firewall rules are added to assure that any traffic does or doesn't
pass. It is assumed that either they aren't necessary, or they will be
setup outside the scope of libvirt.

virtio-pci: add flags to enable/disable legacy/modern
https://bugzilla.redhat.com/show_bug.cgi?id=1182074
Since libvirt still uses a legacy qemu arg format to add a disk, the
manner in which the 'password-secret' argument is passed to qemu needs
to change to prepend a 'file.' If in the future, usage of the more
modern disk format, then the prepended 'file.' can be removed.
Fix based on Jim Fehlig <jfehlig@suse.com> posting and subsequent
upstream list followups, see:
http://www.redhat.com/archives/libvir-list/2016-August/msg00777.html
for details. Introduced by commit id 'a1344f70'.
The first argument should be const char ** instead of
char **, because this is a search function and as such it
doesn't, and shouldn't, alter the haystack in any way.
This change means we no longer have to cast arrays of
immutable strings to arrays of mutable strings; we still
have to do the opposite, though, but that's reasonable.
If any of the devices referenced a USB hub that does not exist,
defining the domain would either fail with:

(if only the last hub in the path is missing)
or crash.
Return a proper error instead of crashing.

On UNIX like systems there are no constraints on what characters

some values that we think of as paths (e.g. disk source) are not
necessarily paths at all. For instance, some hypervisors take
that as an arbitrary identifier and corresponding file is then
looked up by hypervisor in its table. Instead of trying to fix

In qemu, enabling this feature boils down to adding the following
onto the command line:
-global driver=cfi.pflash01,property=secure,value=on
However, there are some constraints resulting from the
implementation. For instance, System Management Mode (SMM) is
required to be enabled, the machine type must be q35-2.4 or
later, and the guest should be x86_64. While technically it is
possible to have 32 bit guests with secure boot, some non-trivial
CPU flags tuning is required (for instance lm and nx flags must
be prohibited). Given complexity of our CPU driver, this is not
trivial. Therefore I've chosen to forbid 32 bit guests for now.
If there's ever need, we can refine the check later.

Add the definitions to allow for viewing/setting cgroup period and quota
limits for IOThreads.
This is similar to the work done for emulator quota and period by
commit ids 'b65dafa' and 'e051c482'.
Being able to view/set the IOThread specific values is related to more
recent changes adding global period (commmit id '4d92d58f') and global
quota (commit id '55ecdae') definitions and qemu support (commit id
'4e17ff79' and 'fbcbd1b2'). With a global setting though, if somehow
the IOThread value in the cgroup hierarchy was set "outside of libvirt"
to a value that is incompatible with the global value.
Allowing control over IOThread specific values provides the capability
to alter the IOThread values as necessary.
Failure to parse the schema file would not trigger a test suite failure.
In addition to making the test fail it's necessary to split up the
parsing of the schema file into a separate test.
This is necessary as the XML validator uses libvirt errors to report
problems parsing of the actual schema RNG needs to be split out into a
separate function and called via virTestRun which has the
infrastructure to report them.
Rather than pass the disks[i]->info.alias to qemuMonitorSetDrivePassphrase
and then generate the "drive-%s" alias from that, let's use qemuAliasFromDisk
prior to the call to generate the drive alias and then pass that along
thus removing the need to generate the alias from the monitor code.
libxl configuration files conversion can now handle USB controllers.
When parting libxl config file, USB controllers with type PV are
ignored as those aren't handled.

The current LUKS support has a "luks" volume type which has
a "luks" encryption format.
This partially makes sense if you consider the QEMU shorthand
syntax only requires you to specify a format=luks, and it'll
automagically uses "raw" as the next level driver. QEMU will
however let you override the "raw" with any other driver it
supports (vmdk, qcow, rbd, iscsi, etc, etc)
IOW the intention though is that the "luks" encryption format
is applied to all disk formats (whether raw, qcow2, rbd, gluster
or whatever). As such it doesn't make much sense for libvirt
to say the volume type is "luks" - we should be saying that it
is a "raw" file, but with "luks" encryption applied.
IOW, when creating a storage volume we should use this XML
<volume>
<name>demo.raw</name>
<capacity>5368709120</capacity>
<target>
<format type='raw'/>
<encryption format='luks'>
<secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccd2f80d6f'/>
</encryption>
</target>
</volume>
and when configuring a guest disk we should use
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/home/berrange/VirtualMachines/demo.raw'/>
<target dev='sda' bus='scsi'/>
<encryption format='luks'>
<secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccd2f80d6f'/>
</encryption>
</disk>
This commit thus removes the "luks" storage volume type added
in

util: Add 'luks' to the FileTypeInfo
The storage file probing code is modified so that it can probe
the actual encryption formats explicitly, rather than merely
probing existance of encryption and letting the storage driver
guess the format.
The rest of the code is then adapted to deal with
VIR_STORAGE_FILE_RAW w/ VIR_STORAGE_ENCRYPTION_FORMAT_LUKS
instead of just VIR_STORAGE_FILE_LUKS.
The commit mentioned above was included in libvirt v2.0.0.
So when querying volume XML this will be a change in behaviour
vs the 2.0.0 release - it'll report 'raw' instead of 'luks'
for the volume format, but still report 'luks' for encryption
format. I think this change is OK because the storage driver
did not include any support for creating volumes, nor starting
guets with luks volumes in v2.0.0 - that only since then.
Clearly if we change this we must do it before v2.1.0 though.

Add support for converting objects nested in arrays with a numbering
discriminator on the command line. This syntax is used for the
object-based specification of disk source properties.
Add a modular parser that will allow to parse 'json' backing definitions
that are supported by qemu. The initial implementation adds support for
the 'file' driver.
Due to the approach qemu took to implement the JSON backing strings it's
possible to specify them in two approaches.
The object approach:
json:{ "file" : { "driver":"file",
"filename":"/path/to/file"
}
}
And a partially flattened approach:
json:{"file.driver":"file"
"file.filename":"/path/to/file"
}
Both of the above are supported by qemu and by the code added in this
commit. The current implementation de-flattens the first level ('file.')
if possible and required. Other handling may be added later but
currently only one level was possible anyways.
For use with memory hotplug virQEMUBuildCommandLineJSONRecurse attempted
to format JSON arrays as bitmap on the command line. Make the formatter
function configurable so that it can be reused with different syntaxes
of arrays such as numbered arrays for use with disk sources.
This patch extracts the code and adds a parameter for the function that
will allow to plug in different formatters.
Until now the JSON->commandline convertor was used only for objects
created by qemu. To allow reusing it with disk formatter we'll need to
escape ',' as usual in qemu commandlines.
Refactor the command line generator by adding a wrapper (with
documentation) that will handle the outermost object iteration.
This patch also renames the functions and tweaks the error message for
nested arrays to be more universal.
The new function is then reused to simplify qemucommandutiltest.
As we already test that the extraction of the backing store string works
well additional tests for the backing store string parser can be made
simpler.
Export virStorageSourceNewFromBackingAbsolute and use it to parse the
backing store strings, format them using virDomainDiskSourceFormat and
match them against expected XMLs.
Failure to parse a XML that was not supposed to fail would result into a
crash in the test suite as the vcpu bitmap would not be filled prior to
the active XML->XML test.
Skip formatting of the vcpu snippet in the fake status XML formatter in
such case to avoid the crash. The test would fail anyways.
There's a plan to rework the address handling, so testcases
that verify hotplugging ccw devices will help in avoiding
regression.
In this commit, some files are duplicated because of the way
qemuhotplug.c calculates the expected xml filenames.
I plan on changing that to explicitly stating the basis domain
xml, the device xml, and the expected xml.
When parsing a command line with USB devices that have
no address specified, QEMU automatically adds a USB hub
if the device would fill up all the available USB ports.
To help most of the users, add one hub if there are more
USB devices than available ports. For wilder configurations,
expect the user to provide us with more hubs and/or controllers.
Resolves a CI test integration failure with a RHEL6/Centos6 environment.
In order to use a LUKS encrypted device, the design decision was to
generate an encrypted secret based on the master key. However, commit
id 'da86c6c' missed checking for that specifically.
When qemuDomainSecretSetup was implemented, a design decision was made
to "fall back" to a plain text secret setup if the specific cipher was
not available (e.g. virCryptoHaveCipher(VIR_CRYPTO_CIPHER_AES256CBC))
as well as the QEMU_CAPS_OBJECT_SECRET. For the luks encryption setup
there is no fall back to the plaintext secret, thus if that gets set
up by qemuDomainSecretSetup, then we need to fail.
Also, while the qemuxml2argvtest has set the QEMU_CAPS_OBJECT_SECRET
bit, it didn't take into account the second requirement that the
ability to generate the encrypted secret is possible. So modify the
test to not attempt to run the luks-disk if we know we don't have
the encryption algorithm.

Generate the luks command line using the AES secret key to encrypt the

We were requiring a USB port path in the schema, but not enforcing it.
Omitting the USB port would lead to libvirt formatting it as (null).
Such domain cannot be started and will disappear after libvirtd restart
(since it cannot parse back the XML).
Only format the port if it has been specified and mark it as optional
in the XML schema.
Commit id's '9bbf0d7e6' and '2552fec24' added some XML parsing tests
for a LUKS volume to use a 'passphrase' secret format. After commit,
this was deemed to be incorrect, so covert the various tests to use
the volume usage format where the 'usage' is the path to the volume
rather than a user defined name string.

In order to use more common code and set up for a future type, modify the
encryption secret to allow the "usage" attribute or the "uuid" attribute
to define the secret. The "usage" in the case of a volume secret would be
the path to the volume as dictated by the backwards compatibility brought
on by virStorageGenerateQcowEncryption where it set up the usage field as
the vol->target.path and didn't allow someone to provide it. This carries
into virSecretObjListFindByUsageLocked which takes the secret usage attribute
value from from the domain disk definition and compares it against the
usage type from the secret definition. Since none of the code dealing
with qcow/qcow2 encryption secrets uses usage for lookup, it's a mostly
cosmetic change. The real usage comes in a future path where the encryption
is expanded to be a luks volume and the secret will allow definition of
the usage field.
This code will make use of the virSecretLookup{Parse|Format}Secret common code.

When support for <interface type='ethernet'> was added in commit
9a4b705f back in 2010, it erroneously looked at <source dev='blah'/>
for a user-specified guest-side interface name. This was never
documented though. (that attribute already existed at the time in the
data.ethernet union member of virDomainNetDef, but apparently had no
practical use - it was only used as a storage place for a NetDef's
bridge name during qemuDomainXMLToNative(), but even then that was
never used for anything).
When support for similar guest-side device naming was added to the lxc
driver several years later, it was put in a new subelement <guest
dev='blah'/>.
In the intervening years, since there was no validation that
ethernet.dev was NULL in the other drivers that didn't actually use
it, innocent souls who were adding other features assuming they needed
to account for non-NULL ethernet.dev when really they didn't, so
little bits of the usual pointless cargo-cult code showed up.
This patch not only switches the openvz driver to use the documented
<guest dev='blah'/> notation for naming the guest-side device (just in
case anyone is still using the openvz driver), and logs an error if
anyone tries to set <source dev='blah'/> for a type='ethernet'
interface, it also removes the cargo-cult uses of ethernet.dev and
<source dev='blah'/>, and eliminates if from the RNG and from
virDomainNetDef.
NB: I decided on this course of action after mentioning the
inconsistency here:
https://www.redhat.com/archives/libvir-list/2016-May/msg02038.html
and getting encouragement do eliminate it in a later IRC discussion
with danpb.
Now that we can include <interface type='ethernet'> in tests, we could
almost test XML that has an <ip> element in an interface. Except that
the test fails when it tries to actually set the IP address for the
interface's tap device. This patch mocks virNetDevSetIPAddress() to
just return success.
These had been declared in conf/device_conf.h, but then used in
util/virnetdev.c, meaning that we had to #include conf/device_conf.h

This caused a bigger problem when I tried to #include util/virnetdev.h
in a file in src/conf (which is allowed) - for some reason the
"device_conf.h: File not found" error.
The solution is to move the data types and functions used in util

(Cache Monitoring technology) and MBM (Memory Bandwidth Monitoring),
to monitor or control shared resource. This patch add them into x86
part of cpu_map.xml to be used for applications based on libvirt to
get cpu capabilities. For example, Nova in OpenStack schedules guests
based on the CPU features that the host has.

The VIR_STORAGE_POOL_EVENT_REFRESHED constant does not
reflect any change in the lifecycle of the storage pool.
It should thus not be part of the storage pool lifecycle
event set, but rather be a top level event in its own
right. Thus we introduce VIR_STORAGE_POOL_EVENT_ID_REFRESH
to replace it.

This partially reverts commit 9b45c9f049.
It changed the default format of socket address from the one SASL
requires, but did not adjust all the callers.
It also removed the test coverage for it.
Revert most of the changes except the virSocketAddrFormatFull support
for URI-formatted strings.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1345743 while
reverting the format used by virt-admin's client-info command from
the URI one to the SASL one.

In cases where we expect parse failure of the test input file the
testsuite can't differentiate if the parser failed when parsing or when
opening the file. Add a call to virFileExists and error out on missing
input files.
Missing output files are partially expected when regenerating test
output.
Move the enum into a new src/util/virsecret.h, rename it to be
virSecretLookupType. Add a src/util/virsecret.h in order to perform
a couple of simple operations on the secret XML and virSecretLookupTypeDef
for clearing and copying.
This includes quite a bit of collateral damage, but the goal is to remove
the "virStorage*" and replace with the virSecretLookupType so that it's
easier to to add new lookups that aren't necessarily storage pool related.

qemuMonitorMigrationParams is a better name for a structure which
contains various migration parameters. While doing that, we should use
full names for individual parameters.

Documentation for the "guest-set-vcpus" command describes a proper
algorithm how to set vcpus. This patch makes the following changes:
- state of cpus that has not changed is not updated
- if the command was partially successful the command is re-tried with
the rest of the arguments to get a proper error message
- code is more robust against malicious guest agent
- fix testsuite to the new semantics
Make them work again... The xml2xml had been working, but the xml2argv
were not working. Making the xml2argv work required a few adjustments to
the xml to update to more recent times.

Since we support QEMU 0.12 and later, checking for support of specific flags
added prior to that isn't necessary.
Thus start with the base of having the "-o options" available for the
qemu-img create option and then determine whether we have the compat
option for qcow2 files (which would be necessary up through qemu 2.0
where the default changes to compat 0.11).
Adjust test to no long check for NONE and FLAG options as well was removing
results of tests that would use that option.

This script can already operate on a list of files.
Add a --check parameter to check if multiple files are wrapped
correctly with a single invocation of the script.
We have a list of parameters in @args, that need to be rewrapped
and separated by a space and escaped newline: " \\\n", with the
exception of the last one, which only needs a newline.
Instead of a for cycle, rewrap the individual arguments using map,
and interleave them with escaped newlines by using join.
This tests checks that the first word after SYNOPSIS
in virsh help ${command} output is ${command}.
This was only good to check that the command option structures
are valid, which is now served by 'virsh self-test'.
A new hidden command for virsh that will iterate over
all command groups and commands and print help for every single one.
This involves running vshCmddefOptParse so we can get an error if
one of the command's option structure is invalid.
