      Oct 27 09:55:24 perf184.perf.lab.eng.bos.redhat.com virtqemud[2860]: Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainCreate)

      Expected results: guest should boot with SRIOV network device

      Additional info: This happens with any network device (Intel,Mellanox) networks.
      If you add a virtio bridge, that works without issue. Do not see this with RHEL9.1.

      XML looks like this which looks the same as a RHEL9.1 Guest

      <hostdev mode='subsystem' type='pci' managed='yes'>
      <source>
      <address domain='0x0000' bus='0x31' slot='0x0a' function='0x0'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x0c' slot='0x00' function='0x0'/>
      </hostdev>
