e958fb5b15 qemu: Report better host-model CPUs in domain caps
One of the main reasons for introducing host-model CPU definition in a
domain capabilities XML was the inability to express disabled features
in a host capabilities XML. That is, when a host CPU is, e.g., Haswell
without x2apic support, host capabilities XML will have to report it as
Westmere + a bunch of additional features., but we really want to use
Haswell - x2apic when creating a host-model CPU.

Unfortunately, I somehow forgot to do the last step and the code would
just copy the CPU definition found in the host capabilities XML. This
changed recently for new QEMU versions which allow us to query host CPU,
but any slightly older QEMU will not benefit from any change I did. This
patch makes sure the right CPU model is filled in the domain
capabilities even with old QEMU.

The issue was reported in
https://bugzilla.redhat.com/show_bug.cgi?id=1426456

Yeah, that's right. A mount point doesn't have to be a directory.

321ff4087c virt-host-validate: add bhyve support
Add bhyve support to virt-host-validate(1). It checks for the
essential kernel modules to be available so that user can actually
start VMs, have networking and console access.

It uses the kldnext(2)/kldstat(2) routines to retrieve modules list.
As bhyve is only available on FreeBSD and these routines were available
long before bhyve appeared, not adding any specific configure checks
for that.

Also, update tools/Makefile.am to add
virt-host-validate-$driver.[hc] to the build only if the
appropriate driver is enabled.

0623945c40 tests: Add createVHBAByStoragePool-by-parent to fchosttest
Add a new test to fchosttest in order to test creation of our vHBA
via the Storage Pool logic.  Unlike the real code, we cannot yet use
the virVHBA* API's because they (currently) traverse the file system
in order to get the parent vport capable scsi_host. Besides there's
no "real" NPIV device here - so we have to take some liberties, at
least for now.

Instead, we'll follow the node device tests partially in order to
create and destroy the vHBA with the test node devices.

e915942b05 qemuProcessHandleMonitorEOF: Disable namespace for domain
https://bugzilla.redhat.com/show_bug.cgi?id=1430634

If a qemu process has died, we get EOF on its monitor. At this
point, since qemu process was the only one running in the
namespace kernel has already cleaned the namespace up. Any
attempt of ours to enter it has to fail.

This really happened in the bug linked above. We've tried to
attach a disk to qemu and while we were in the monitor talking to
qemu it just died. Therefore our code tried to do some roll back
(e.g. deny the device in cgroups again, restore labels, etc.).
However, during the roll back (esp. when restoring labels) we
still thought that domain has a namespace. So we used secdriver's
transactions. This failed as there is no namespace to enter.

887ffbce43 qemuxml2argvtest: Don't overwrite driver stateDir
This is a very historic artefact. Back in the old days of
830ba76c3e when we had macros to add arguments onto qemu command
line (!) we thought it was a good idea to let qemu write out the
PID file. So we passed -pidfile $stateDir/$domName onto the
command line. Thus, in order for tests to work we needed stable
stateDir in the qemu driver. Unfortunately, after 16efa11aa6
where stateDir is mkdtemp()-d, this approach lead to a leak of
temp dir.

8af68ea478 qemu: hotplug: Reset device removal waiting code after vCPU unplug
If the delivery of the DEVICE_DELETED event for the vCPU being deleted
would time out, the code would not call 'qemuDomainResetDeviceRemoval'.

Since the waiting thread did not unregister itself prior to stopping the
waiting the monitor code would try to wake it up instead of dispatching
it to the event worker. As a result the unplug process would not be
completed and the definition would not be updated.

cd4a8b9304 conf: store "autoGenerated" for graphics listen in status XML
When libvirtd is started we call qemuDomainRecheckInternalPaths
to detect whether a domain has VNC socket path generated by libvirt
based on option from qemu.conf.  However if we are parsing status XML
for running domain the existing socket path can be generated also if
the config XML uses the new <listen type='socket'/> element without
specifying any socket.

The current code doesn't make difference how the socket was generated
and always marks it as "fromConfig".  We need to store the
"autoGenerated" value in the status XML in order to preserve that
information.

The difference between "fromConfig" and "autoGenerated" is important
for migration, because if the socket is based on "fromConfig" we don't
print it into the migratable XML and we assume that user has properly
configured qemu.conf on both hosts.  However if the socket is based
on "autoGenerated" it means that a new feature was used and therefore
we need to leave the socket in migratable XML to make sure that if
this feature is not supported on destination the migration will fail.
