Seems like in 4.3.9 CPU was set to -machine pc-i440fx-rhel7.6.0,accel=kvm,usb=off,dump-guest-core=off \ -cpu Skylake-Server,spec-ctrl=on,ssbd=on,md-clear=on \ while on 4.4.0 it's set to: <cpu match="exact"> <model>Cascadelake-Server</model> <feature name="md-clear" policy="require"/> <feature name="mds-no" policy="require"/> <feature name="hle" policy="disable"/> <feature name="rtm" policy="disable"/> <feature name="tsx-ctrl" policy="require"/> <feature name="arch-capabilities" policy="require"/> <topology cores="2" sockets="16" threads="1"/> <numa> <cell cpus="0-31" id="0" memory="16777216"/> </numa> </cpu> and it fails on missing tsx-ctrl feature. Maybe related to partial implementation on *Bug 1674420* <https://bugzilla.redhat.com/show_bug.cgi?id=1674420> - [RFE] - add support for Cascadelake-Server CPUs (and IvyBridge) which is targeted to 4.4.2? Gianluca, can you confirm your host has Cascadelake-Server CPU ? If so, please note Cascadelake is not listed in supported CPUs: https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_... -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/> [image: |Our code is open_] <https://www.redhat.com/en/our-code-is-open> *Red Hat respects your work life balance.
