As discussed on the upstream list, it's better not to make this
kind of predictions in libvirt. It may happen that qemu learns
how to enable OVMF on other architectures too and we shouldn't
try to chase that.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
Currently, we are whitelisting architectures, that we know how to run
OVMF on. So far, only x86_64 was enabled. However, looking at qemu
code, the same commandline can be used to enable OVMF for armv7l and
aarch64.

I noticed this while working on qemuDomainGetBlockInfo. Assigning
a bool value to an int variable compiles fine, but raises red flags
on the maintenance front as it becomes too easy to assign -1 or 2
or any other non-bool value to the same variable.

Use of an 'int' to represent a 'bool' value is confusing. Just
because dbus made the mistake of cementing their 4-byte wire
format of dbus_bool_t into their API doesn't mean we have to
repeat the mistake. With a little bit of finesse, we can
guarantee that we provide a large-enough value to the DBus
code, while still copying only the relevant one-byte bool
to the client code, and isolate the rest of our code base from
the DBus stupidity.

This function returned non-inactive domains instead of active
domains. This broke virConnectNumOfDefinedDomains() and
virConnectListDefinedDomains() functions.
Ethernet interfaces in libvirt currently do not support bandwidth setting.
For example, following xml file for an interface will not apply these
settings to corresponding qdiscs.
<interface type="ethernet">
<mac address="02:36:1d:18:2a:e4"/>
<model type="virtio"/>
<script path=""/>
<target dev="tap361d182a-e4"/>

Since 1.2.8 it's possible to use OVMF on domains. Moreover, it's
possible to have libvirt create NVRAM file per domain. Later,
when domain is undefined, the file is removed too. However,
things are a bit complicated when domain's transient. There's no
undefine to transient domains. There are two options: 1) leave
the file behind and let mgmt app remove it. 2) remove it
automatically as domain dies.
But, in some scenarios mgmt app may want to preserve the file,
copy it somewhere safe, and then copy it back when the domain is
starting again. And this wouldn't be possible with case 2). So,
even though case 1) leaves some files behind (possibly undeleted
for a long time), the files themselves are small (128K each). And
data loss is worse than full disk, isn't it?

For some reason, commit id '72b4151f' triggered a Coverity uninitialized
'reply' variable check when referenced within the for loop.
It seems Coverity doesn't know that flags will have to be either AFFECT_LIVE
or AFFECT_CONFIG after the virDomainLiveConfigHelperMethod call.
By adding a "sa_assert()" to confirm that fact, Coverity is happy again.

After a disk is hotunplugged a subsequent call to qemuDomainGetBlockIoTune
to get the --config settings of that disk will fail because the disk is no
longer found by qemuDiskPathToAlias causing an unexpected failure.
Since only the --live flag needs to have the disk device pointer, move the
fetch inside the (flags & VIR_DOMAIN_AFFECT_LIVE) condition. This will also
affect the results if no flags are provided or the --current flag is provided.

The recent commit to add support for block_set_io_throttle parameters
from version 1.7 of qemu did not add any tests - this adds the tests
Signed-off-by: John Ferlan <jferlan@redhat.com>
Seems the 'size_iops_sec' was a late add and the checks for whether
the field was defined, but unsupported and the maximum size of the
field were not being made.
Also, adjust blkdeviotune support error message for grammar, spelling
(paramater), and remove the "(need QEMU 1.7 or superior)". None of
our other similar error messages list which QEMU version is required.

Change while () { smth; last; } to if () { smth; } as 'last' in perl is
analogous to 'break' in C. These are probably copy-paste leftovers from

In bracket-spacing.pl, the current $line is being modified in $data.
That, however, spoils that $data for another check. Introduce new
$tmpdata variable that can be used for temporary modifications. The
difference between $data and $line is that $data are as much cleaned as
possible from non-code blocks and these changes must be kept.

Rule sc_prohibit_newline_at_end_of_diagnostic for syntax-check does
check for passing strings ending with '\n' two lines after known

A previous commit introduced use of locking with invocation
of iptables in the viriptables.c module
commit ba95426d6f
Author: Serge Hallyn <serge.hallyn@ubuntu.com>
Date: Fri Nov 1 12:36:59 2013 -0500
util: use -w flag when calling iptables
This only ever had effect with the virtual network driver,
as it was not wired up into the nwfilter driver. Unfortunately
in the firewall refactoring the use of the -w flag was
accidentally lost.
This patch introduces it to the virfirewall.c module so that
both the virtual network and nwfilter drivers will be using
it. It also ensures that the equivalent --concurrent flag
to ebtables is used.
Since QEMU 1.2.0, we switched to QMP probing instead of parsing -help
(and other commands, such as -cpu ?) output. However, if QMP probing
failed, we still tried starting QEMU with various options and parsing
the output, which was guaranteed to fail because the output changed.
Let's just refuse parsing -help for QEMU >= 1.2.0.

We used to set migration capabilities only when a user asked for them in
flags. This is fine when migration succeeds since the QEMU process is
killed in the end but in case migration fails or if it's cancelled, some
capabilities may remain turned on with no way to turn them off. To fix
that, migration capabilities have to be turned on if requested but
explicitly turned off in case they were not requested but QEMU supports
them.

Recent commit 12bd207e21 fixed few
VSH_OT_STRING options that should've been VSH_OT_DATA. That lead me to
this commit that enforces people to check that newly added options have
proper type. Thanks to virsh erroring out with error message, this will
immediately show up in 'make check' thanks to our virsh-synopsis test.

Even though vshCmddefOptParse() tried returning -1 if there was an
optional option specification that preceded a required one, it failed to
check that for boolean type options and options with VSH_OFLAG_REQ_OPT
flag set. On the other hand, it makes sense that VSH_OT_ARGV is
specified at the end of the option list.
Returning -1 enforces the proper ordering thanks to virsh-synopsis test
in 'make check'.

According to comments in parsing functions, optional options should be
specified *after* required ones. It makes sense and help output looks
cleaner. The only exceptions are options with type == VSH_OT_ARGV.

Rather than just picking the first CD (or failing that, HDD) we come
across, if the user has picked a boot device ordering with <boot
order=''>, respect that (and just try to boot the lowest-index device).
Adds two sets of tests to bhyve2xmlargv; 'grub-bootorder' shows that we
pick a user-specified device over the first device in the domain;
'grub-bootorder2' shows that we pick the first (lowest index) device.
When user calls setmem on a running LXC machine, we do update its cgroup
entry, however we neither update domain's runtime XML nor
we update our internal structures and this patch fixes it.

The API docs generators were broken by the header file
re-organization. Specifically
* html/libvirt-libvirt.html was empty (and should be deleted)
* Makefile.am didn't install html/libvirt-libvirt-*.html
* hvsupport.html was mostly empty
* sitemap.html.in didn't list the new html/*.html files
Commit 6e5c79a1 tried to fix deadlock between nwfilter{Define,Undefine}
and starting of guest, but this same deadlock exists for
updating/attaching network device to domain.
The deadlock was introduced by removing global QEMU driver lock because
nwfilter was counting on this lock and ensure that all driver locks are
locked inside of nwfilter{Define,Undefine}.
This patch extends usage of virNWFilterReadLockFilterUpdates to prevent
the deadlock for all possible paths in QEMU driver. LXC and UML drivers
still have global lock.

In one of my previous patches (3a3c3780b) I've tried to fix the
problem of nvram path disappearing on a domain that's been
started and shut down again. I fixed this by explicitly saving
domain's config file. However, I did a bit of clumsy without
realizing we have a transient domains for which we don't save the
config file. Hence, any domain using UEFI became persistent.
