[ovirt-users] Nested KVM - vdsm-hook-nestedvt

[Winfried de Heiden]

Hi all and happy new year!

I'm running oVirt 3.6 on EL7.

In order to test nested-kvm I installed vdsm-hook-nestedvt on the 
hypervisor and put "fake_kvm_support = true" in /etc/vdsm/vdsm.conf.

However, afterwards the hypervisor host cannot connect to the ovirt 
Manager, on ovirt Manager the engine.log will tell:

2016-01-01 15:21:42,105 WARN 
[org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] 
(DefaultQuartzScheduler_Worker-76) [71d1638c] Correlation ID: 29daf92c, 
Call Stack: null, Custom Event ID: -1, Message: Host bigvirt moved to 
Non-Operational state as host does not meet the cluster's minimum CPU 
level. Missing CPU features : model_Opteron_G3

After removing the option all works well again, but I'ḿ lacking the 
nested kvm option :( Is nested kvm only supported on a limited cpu's??
