QEMU chardevs have a bug which makes the vhostuser backend complain
about lack of support for FD passing when validating the chardev.
While this is ultimately QEMU's responsibility to fix, libvirt needs to
avoid tickling the bug.
Simply disabling chardev FD passing just for vhostuser's chardev is
the most prudent approach, avoiding need for a QEMU version number
check.

When creating a snapshot with --quiesce an async job is grabbed
and just before executing guest fs-freeze command an agent job is
grabbed. This is achieved by calling
qemuDomainObjBeginJobInternal(job = QEMU_JOB_NONE,

Since there already is an async job set on the domain (by the
same thread) qemuDomainNestedJobAllowed(priv, job) is consulted
if @job is allowed by job mask. But this function returns false
(meaning sync @job is not allowed) which leads to a deadlock.

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".
See also 124441_AMD64_SpeculativeStoreBypassDisable_Whitepaper_final.pdf
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

Here we opt the easy way to check if srcPriv is not NULL so that we
