Description of problem:
High performance VM fails to start due to:

    message: 'server error. command SyncVMI failed: "LibvirtError(Code=67, Domain=10,
      Message=''unsupported configuration: kvm-hint-dedicated=on is only applicable
      for cpu host-passthrough'')"'
    reason: Synchronizing with the Domain failed.
    status: "False"
    type: Synchronized

This was fixed in libvirt bug 1857671 (libvirt-7.3.0-1.el8)
but 4.10 currently uses 7.0.0-14


Version-Release number of selected component (if applicable):
CNV 4.10.0 (virt v4.10.0-124)


How reproducible:
100%

Steps to Reproduce:
1. Create VM from rhel high performance template (rhel8-highperformance-tiny)
2. Start the VM
3.

Actual results:
VMI fails to run
VM errors on:

    Message:               server error. command SyncVMI failed: "LibvirtError(Code=67, Domain=10, Message='unsupported configuration: kvm-hint-dedicated=on is only applicable for cpu host-passthrough')"
    Reason:                Synchronizing with the Domain failed.


Expected results:
VM should successfully start.
