I'm also subscribing the UCA Team as I personally only know about [1] which allows you to use named CPU models.

I expect there already is some general pattern established to handle e.g. the older MDS which if you look at "Configuration as a Hypervisor" at [2] also needs such <feature...> entries to be configured through libvirt.
Eventually dropping hle/rtm is no different than adding md-clear back then.

@UCATeam - How would in a OS/Charm world one add/disable individual cpu features?
Could you outline how this is handled today so we might consider adapting the same for hle/rtm?
