Hello, I'm trying what in subject as a nested environment. Physical is oVirt 4.3.9 Me too.
I configured the VM that has to be the hypervisor with cpu passthrough. The local VM starts ok with these settings:
usr/libexec/qemu-kvm -name guest=HostedEngineLocal,debug-threads=on -S -object secret,id=masterKey0,format=raw,file=/var/lib/libvirt/qemu/domain-1-HostedEngineLocal/master-key.aes -machine pc-q35-rhel8.1.0,accel=kvm,usb=off,dump-guest-core=off -cpu Cascadelake-Server,ss=on,hypervisor=on,tsc-adjust=on,umip=on,pku=on,md-clear=on,stibp=on,arch-capabilities=on,ibpb=on,rdctl-no=on,ibrs-all=on,skip-l1dfl-vmentry=on,mds-no=on,kvmclock=on
When at final stage of deployment it tries to start the final engine VM it goes down due to this in vdsm.log:
I have just completed a HCI setup with 4.4beta4, thanks Gianluca for you character by character workaround for step 1 of that wizard, and don't have the cpu flags problem. The wizard completed successfully and I now have a working 4.4beta4 engine using glusterfs, :-) output of lscpu: CPU family: 6 Model: 85 Model name: Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz Stepping: 4 And I used Pass-Through Host CPU for the VM that is acting as the next level host and thus runs the hosted-engine.
