IMHO  the LPC thing is definitely in scope for correct modelling in
the XML.

For the MSRs option, it is probable we'd consider that in scope as
well. Currently KVM has a global "ignore unknown msrs" option in the
kernel module, but I think it is conceptually reasonable to expect
that to be settable on a per-VM basis.

Probably would do the MSRs thing as a <features> flag, as we stuff
lots of random feature toggles under there
