I don't see anything wrong with you configs. There were some changes related to SCSI hostdevs, between 6.7.0 an 6.8.0, but none of them should actually impact that use case. Said that, could you please post the actual qemu command lines that libvirt formatted for the two VMs you mention above. The command line can be found in /var/log/libvirt/qemu/$VMNAME.log . Please make sure you post the latest/actual one. It'll help showing whether anything changed between the two or there is a different problem.
