Did you installed vdsm-hook-nestedvt on your L0 hosts? if vdsm-hook-nestedvt is there and cat /sys/module/kvm_intel/parameters/nested reports Y, shutting down and restarting your L1 VMs from oVirt should be enough. > > > > >> I defined the VM like any other, just with one special option > >> enabled: > >> to be run on the L0 host which has the nested support enabled.
