Hi all,

For testing purposes I installed vdsm-hook-nestedvt:

rpm -qi vdsm-hook-nestedvt.noarch

Name        : vdsm-hook-nestedvt           Relocations: (not relocatable)
Version     : 4.16.10                           Vendor: (none)

Summary     : Nested Virtualization support for VDSM
Description :
If the nested virtualization is enabled in your kvm module
this hook will expose it to the guests.

Installation looks fine on the oVirt (AMD cpu) KVM-host:

[root@bigvirt ~]# cat /sys/module/kvm_amd/parameters/nested
1

and in oVirt manager "50_nestedvt" will show up  in Host Hooks. However, trying to install "oVirt Node Hypervisor 3.5" it will warn "No virtualization Hardware was detected". Also, the svm flag is not shown on the guest machine.
Am I missing something? Why is nested kvm not working?
