[ovirt-users] Can't run nested virtualization

Hi, We're running oVirt version 4.3.3, and trying to configure one of the hosts to support Nested Virtualization, but when installing the nested host it claims it doesn't support hardware virtualization. On the physical host, we've enabled nested virtualization: # cat /sys/module/kvm_intel/parameters/nested Y Content of /etc/modprobe.d/kvm.conf: options kvm_intel nested=1 options kvm_intel enable_shadow_vmcs=1 options kvm_intel enable_apicv=1 options kvm_intel ept=1 I created a VM to run on that host, which will be the nested host. I try to deploy it but the engine will show it failed because: 2019-05-10 09:11:32,006+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (VdsDeploy) [6381e662] EVENT_ID: VDS_INSTALL_IN_PROGRESS_ERROR(511), An error has occurred during installation of Host host1: Failed to execute stage 'Setup validation': Hardware does not support virtualization. Am I missing something here? Thanks.
