An RNG device can consists of more devices than RND device
itself. For instance, in case of EGD there is a chardev that
connects to EGD daemon and feeds the qemu with random data. When
doing RNG device removal we have to remove the associated chardev
as well.

There are two functions called from syncNicRxFilterMultiMode:
virNetDevSetRcvAllMulti() and virNetDevSetRcvMulti(). Both of
them return 0 on success and -1 on error. However, currently
their return value is checked for != 0 which conflicts with our
assumptions on retvals: a positive value is still considered
success but with current check it would lead to failure.

Unlike with SPICE and SDL which use the <gl> subelement to enable OpenGL
acceleration, specifying egl-headless graphics in the XML has
essentially the same meaning, thus in case of egl-headless we don't have

in the 'rendernode' one further down the road.

Up until now, we formatted 'rendernode=' onto QEMU cmdline only if the
user specified it in the XML, otherwise we let QEMU do it for us. This
causes permission issues because by default the /dev/dri/renderDX
permissions are as follows:
crw-rw----. 1 root video
There's literally no reason why it shouldn't be libvirt picking the DRM
render node instead of QEMU, that way (and because we're using
namespaces by default), we can safely relabel the device within the

This is the first step towards libvirt picking the first available
render node instead of QEMU. It also makes sense for us to be able to do
that, since we allow specifying the node directly for SPICE, so if
there's no render node specified by the user, we should pick the first
available one. The algorithm used for that is essentially the same as
the one QEMU uses.

Guest network devices can set 'overflow' when there are a number of multicast
ips configured. For virtio_net, the limit is only 64. In this case, the list

Since commit v4.3.0-336-gc84726fbdd all
{hypervisor-,}cpu-{baseline,compare} commands use a generic
vshExtractCPUDefXMLs helper for extracting individual CPU definitions
from the provided input file. The helper wraps the input file in a
<container> element so that several independent elements can be easily
parsed from the file. This works fine except when the file starts with
XML declaration (<?xml version="1.0" ... ?>) because the XML declaration
cannot be put inside any element. In fact it has to be at the very
beginning of the XML document without any preceding white space
characters. We can just simply skip the XML declaration.

Post-copy migration has been broken on the source since commit
v3.8.0-245-g32c29f10db which implemented support for
pause-before-switchover QEMU migration capability.
Even though the migration itself went well, the source did not really
know when it switched to the post-copy mode despite the messages logged
by MIGRATION event handler. As a result of this, the events emitted by
source libvirtd were not accurate and statistics of the completed
migration would cover only the pre-copy part of migration. Moreover, if
migration failed during the post-copy phase for some reason, the source
libvirtd would just happily resume the domain, which could lead to disk
corruption.
With the pause-before-switchover capability enabled, the order of events
emitted by QEMU changed:
pause-before-switchover
disabled enabled
MIGRATION, postcopy-active STOP
STOP MIGRATION, pre-switchover
MIGRATION, postcopy-active
The STOP even handler checks the migration status (postcopy-active) and
sets the domain state accordingly. Which is sufficient when
pause-before-switchover is disabled, but once we enable it, the
migration status is still active when we get STOP from QEMU. Thus the
domain state set in the STOP handler has to be corrected once we are
notified that migration changed to postcopy-active.
This results in two SUSPENDED events to be emitted by the source
libvirtd during post-copy migration. The first one with
VIR_DOMAIN_EVENT_SUSPENDED_MIGRATED detail, while the second one reports
the corrected VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY detail. This is
inevitable because we don't know whether migration will eventually
switch to post-copy at the time we emit the first event.

There are certain cases e.g. containers where the sysfs path might
exists, but might fail. Unfortunately the exact restrictions are only
known to libvirt when trying to write to it so we need to try it.
But in case it fails there is no need to fully abort, in those cases try
to fall back to the older ioctl interface which can still work.
That makes setting up a bridge in unprivileged LXD containers work.
