After 27726d8c21 a privateData is allocated in
virDomainHostdevDefAlloc(). However, the counter part - freeing
them in Free() is missing which leads to the following memory

This is preferrable to -nographic which (in addition to disabling
graphics output) redirects the serial port to stdio and on OpenBIOS
enables the firmware's serial console.

Libxl is the last user and I don't have the toolchain prepared to
compile the libxl driver. Move it to the libxl driver to avoid having to
refactor the code.
Currently, we have libvirt-client library which serves as a
collection point for all the libraries and client binaries we
have. Therefore we have couple of silly dependencies, for
instance libvirt-daemon depends on libvirt-client. Only because
the shared library is in the client package.
To solve this, new package libvirt-libs is introduced where all
the libraries are going to live. The client package is then set
to depend on this new package, just like the rest of packages
that suffer the same problem.

This is just a convenience method for discarding a list of filters instead of
using a 'for' loop everywhere. It is safe to pass -1 as the number of elements
in the list as well as passing NULL as list reference.

Provide a separate method to free a logging filter object. This will come handy
once a method to create an individual logging filter object is introduced.

Same as with outputs; since the operations will be further divided into smaller
tasks, creating a filter will become a separate operation that will return
a reference to a newly created filter.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
Right now, we define outputs one after another. However, the correct flow
should be to define a set of outputs as a whole unit. Therefore each output
should be first created, placed into an array/list and the list will be
defined. Output creation should be a separate operation, so an output will be
returned by a reference. From that perspective, it makes perfect sense to
only store pointers to actual outputs.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
In this particular case, reset is meant as clearing the whole list of
outputs/filters, not resetting it to a predefined default setting. Looking at
it from that perspective, returning the number of records removed doesn't help
the caller in any way (not that any of the callers would actually check for
it). Well, callers could detect an error from the number of successfully
removed records, but the only thing that can fail in virLogReset is force
closing a file descriptor in which case the error isn't propagated back to
virLogReset anyway. Conclusion: there is no practical use for having a return
type of 'int' rather than 'void' in this case.

Due to the way the hardware works, KVM on ppc64 always requires
memory locking; however, that is not the case for non-KVM ppc64
guests, eg. ppc64 guests that are running on x86_64 with TCG.
Only require memory locking for ppc64 guests if they are using
KVM or, as it's the case for all architectures, they have host
devices assigned using VFIO.

For type='ethernet' interfaces only.
(This patch had been pushed earlier in
commit 0b4645a7e0, but was reverted in
commit 84d47a3cce because it had been
accidentally pushed during the freeze for release 2.0.0)
(This patch had been pushed earlier in
commit cd5c9f21de, but was reverted in
commit 1549f16832 because it had been
accidentally pushed during the freeze for release 2.0.0)
This will apply to any IP address setting that uses
virNetDevIPInfoAddToDev() (which so far is only the guest-side of LXC
type='ethernet' interfaces).
(This patch had been pushed earlier in
commit cb20f989df, but was reverted in
commit cba06aea8d because it had been
accidentally pushed during the freeze for release 2.0.0)
This is place as a sub-element of <source>, where other aspects of the
host-side connection to the network device are located (network or
bridge name, udp listen port, etc). It's a bit odd that the interface
we're configuring with this info is itself named in <target dev='x'/>,
but that ship sailed long ago:
<interface type='ethernet'>
<mac address='00:16:3e:0f:ef:8a'/>
<source>
<ip address='192.168.122.12' family='ipv4'
prefix='24' peer='192.168.122.1'/>
<ip address='192.168.122.13' family='ipv4' prefix='24'/>
<route family='ipv4' address='0.0.0.0'
gateway='192.168.122.1'/>
<route family='ipv4' address='192.168.124.0' prefix='24'
gateway='192.168.124.1'/>
</source>
</interface>
In practice, this will likely only be useful for type='ethernet', so
its presence in any other type of interface is currently forbidden in
the generic device Validate function (but it's been put into the
general population of virDomainNetDef rather than the
ethernet-specific union member so that 1) we can more easily add the
capability to other types if needed, and 2) we can retain the info
when set to an invalid interface type all the way through to
validation and report a proper error, rather than just ignoring it
(which is currently what happens for many other type-specific
settings).
(NB: The already-existing configuration of IP info for the guest-side
of interfaces is in subelements directly under <interface>, and the
name of the guest-side interface (when configurable) is in <guest
dev='x'/>).
(This patch had been pushed earlier in
commit fe6a77898a, but was reverted in
commit d658456530 because it had been
accidentally pushed during the freeze for release 2.0.0)
The peer attribute is used to set the property of the same name in the
interface IP info:
<interface type='ethernet'>
...
<ip family='ipv4' address='192.168.122.5'
prefix='32' peer='192.168.122.6'/>
...
</interface>
Note that this element is used to set the IP information on the
*guest* side interface, not the host side interface - that will be
supported in an upcoming patch.
(This patch now has quite a history: it was originally pushed in
commit 690969af, which was subsequently reverted in commit 1d14b13f,
then reworked and pushed (along with a lot of other related/supporting
patches) in commit 93135abf1; however *that* commit had been
accidentally pushed during dev. freeze for release 2.0.0, so it was
again reverted in commit f6acf039f0).

This patch takes the code out of
lxcContainerRenameAndEnableInterfaces() that adds all IP addresses and
IP routes to the interface, and puts it into a utility function
virNetDevIPInfoAddToDev() in virnetdevip.c so that it can be used by
anyone.
One small change in functionality -
lxcContainerRenameAndEnableInterfaces() previously would add all IP
addresses to the interface while it was still offline, then set the
interface online, and then add the routes. Because I don't want the
utility function to set the interface online, I've moved this up so
the interface is first set online, then IP addresses and routes are
added. This is the same order that the network service from
initscripts (in ifup-ether) does it, so it shouldn't pose any problem
(and hasn't, in the tests that I've run).

Introduce a helper to help determine if a disk src could be possibly used
for a disk secret... Going to need this for hot unplug.
Signed-off-by: John Ferlan <jferlan@redhat.com>
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.

Add a new secret type known as "passphrase" - it will handle adding the
secret objects that need a passphrase without a specific username.
The format is:

<usage type='passphrase'>

</usage>
</secret>

I can't think of any good reason to do either of those, and having the

can't be bothered to read the entire page.
On error, asprintf returns -1 and the contents of the string
pointer is undefined. In the rest of the libvirt code,
the virAsprintf wrapper takes care of that.
Check the return value and report a generic error, since we
purposefully avoid linking to virutil.
The default Fedora build roots for f25 and newer no longer

A helper that will execute a callback on every USB device

With an ability to skip USB hubs, since we will want to treat
them differently in some cases.
I'm not sure why our code claimed "-boot menu=on" cannot be used in
combination with per-device bootindex, but it was proved wrong about
four years ago by commit 8c952908. Let's always use bootindex when QEMU
supports it.
