RHEL-AV Bug related to this issue, https://bugzilla.redhat.com/show_bug.cgi?id=1857671 I'm trying to understand how it is that we didn't spot this before now. This worked in the past? Were we testing this configuration? Understood that the libvirt error appears, but there's also a warning about the VM not having enough memory. Michal, It appears that we're running into an error that was fixed in 8.5 (Per Comment #1). Is it this fix a candidate for backporting to 8.4? If so, what's the process we need to follow? We're using the identical libvirt versions for both 4.9 and 4.10: 7.0.0-14 So the mystery to me is how did the previous version pass where this one fails? @sgott this works in 4.9.1. Attaching VM spec from both versions. *** Bug 2035679 has been marked as a duplicate of this bug. *** libvirt has now shipped a fix for this. Moving BZ to MODIFIED as we should pick this up with the next images we build. Both RHEL and Windows related High Performance Template Related tests have PASSED. VERIFIED With v4.10.0-648 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Moderate: OpenShift Virtualization 4.10.0 Images security and bug fix update), and where to find the updated files, follow the link below.

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.
