When reviewing 00d9edfe2f I've changed proposed patch and
made it to not report error if no domain is found. This is wrong
and the original patch was okay. Thing is, both callers pass
occurrence = OptionalItem so no error message overwriting is done
as I thought initially.

AMD x86 CPUs have two separate ways to mitigate the Speculative Store
Bypass hardware flaw. In current processors only non-architectural MSRs
are available, and so hypervisors must expose a virtualized MSR and CPU
flag "virt-ssbd" (CPUID Function 8000_0008, EBX[25]=1).
In future processors AMD will provide an architectural MSR, indicated by
existance of the CPUID Function 8000_0008, EBX[24]=1, to which QEMU has
given the name "amd-ssbd".
The "amd-ssbd" flag should be used in preference to "virt-ssbd", if it
is available, since it provides improved performance. For virtual
machine configuration, both should be exposed when available, to allow
for maximal guest OS compatibility as not all guests yet support both.
If future processes are not vulnerable to the flaw, this will be
indicated by the existance of CPUID Function 8000_0008, EBX[26]=1,
to which QEMU has given the name "amd-no-ssb".

from:
https://bugzilla.kernel.org/show_bug.cgi?id=199889
Note that neither amd-ssbd or amd-no-ssb will be reported by the kernel
in /proc/cpuinfo. It knows about these CPUID bits and does the right thing,
but doesn't report their existance as distinct flags in /proc/cpuinfo.

Currently we format the serial, geometry and error policy on the -drive
backend argument.
QEMU added the ability to set serial and geometry on the frontend in
the 1.2 release deprecating use of -drive, with support being deleted
from -drive in 3.0.
We keep formatting error policy on -drive for now, because we don't
ahve support for that with -device for usb-storage just yet.
Note that some disk buses (sd) still don't support -device. Although
QEMU allowed these properties to be set on -drive for if=sd, they
have been ignored so we now report an error in this case.

The private data of a virStorageSource which is backing an iSCSI hostdev
may be NULL if no authentication is present. The code handling the
hotplug would attempt to extract the authentication info stored in
'secinfo' without checking if it is allocated which resulted in a crash.
Here we opt the easy way to check if srcPriv is not NULL so that we
don't duplicate all the logic which selects whether the disk source has
a secret.

When libvirtd is restarted, it checks that each guest tap device is
still attached to the bridge device that the configuration info says
it should be connected to. If not, the tap will be disconnected from
[wherever it is] and connected to [wherever it should be].
The previous code that did this did not account for:
1) the IFLA_MASTER attribute in a netdev's ifinfo will be set to
"ovs-system" for any tap device connected to an OVS bridge, *not*
to the name of the bridge it is attached to.
2) virNetDevRemovePort() only works for devices that are attached to a
standard Linux host bridge. If a device is currently attached to an
OVS bridge, then virNetDevOpenvswitchRemovePort() must be called
instead.
This patch remedies those problems, and adds a couple of information
log messages to aid in debugging any future problem.

This function retrieves the name of the OVS bridge that the given
netdev is attached to. This separate function is necessary because OVS
set the IFLA_MASTER attribute to "ovs-system" for all netdevs that are

master can't be used.

Once we called qemuDomainObjEnterRemote to talk to the destination
daemon during a peer to peer migration, the vm lock is released and we
only hold an async job. If the source domain dies at this point the
monitor EOF callback is allowed to do its job and (among other things)
clear all private data irrelevant for stopped domain. Thus when we call
qemuDomainObjExitRemote, the domain may already be gone and we should
avoid touching runtime private data (such as current job info).
In other words after acquiring the lock in qemuDomainObjExitRemote, we
need to check the domain is still alive. Unless we're doing offline
migration.
