Fixed In Version: ovirt-engine-4.1.9.1
Doc Type: Enhancement
Doc Text:
The Software subtab in the Host General pane now contains a new "Kernel Features" field showing the PTI, IBPB, and IBRS kernel features of the host system, if the information is available. The Virtual Machine General pane now contains a new "Guest CPU Type" field showing the guest machine CPU type. These can be used to easily recognize if meltdown fixes are applied. For more info on meltdown patches detection, see https://access.redhat.com/solutions/3317841.

Description Michal Skrivanek 2018-01-08 09:50:36 UTC 
Display the status of PTI, IBRS and IBPB in host subtab. 
A warning ("!") can be displayed when the host doesn't have any such support.

Display the status of actual running CPU model in guest in VM subtab
Comment 1 Michal Skrivanek 2018-01-08 12:17:26 UTC 
vdsm can report capabilities - separately for each, to be interpreted by engine.
VM's running CPU is already being reported but not used anywhere.
