[libvirt] [BUG] Hyper-V Enlightenments are broken in 5.5.0+

[Vitaly Kuznetsov]

Hi,

when some Hyper-V enlightenments are added to the domain configuration,
e.g.

  <features>
    ...
    <hyperv>
      ..
      <vpindex state='on'/>
    </hyperv>
  ...

I'm observing the following:

# virsh create /etc/libvirt/qemu/win2k16.xml 
error: Failed to create domain from /etc/libvirt/qemu/win2k16.xml
error: unsupported configuration: host doesn't support hyperv 'vpindex' feature

the feature is, of course, supported in KVM/QEMU.

I've bisected the problem to the particular commit:

commit 63acb7bfd56f117309e4fcaf438639d4d7bc7dcb
Author: Jiri Denemark <jdenemar at redhat.com>

    qemu_process: Prefer generic qemuMonitorGetGuestCPU

Any ideas?
