Hi, I've done some research on a bug which I found on the AMD Zen/Zen+ based CPU's. Apparently, when using nested virtualization, the CPU doesn't expose the "monitor" CPU flag. While other virtualization solutions (Xen, ESXi, Hyper-V) don't care about this issue and let you run with nested without any problem, oVirt doesn't let you launch or create any VM and it complains that this "monitor" CPU flag is missing. Since QEMU/KVM cannot do anything about it, I was wondering if the ovirt dev team could ignore this flag please.
