Should we instead of (or in addition to) this also make the same change
in core2_vpmu_do_wrmsr()?
Currently there's no need for this since - afaict - PV guests can't
write this MSR directly (it's not among the white listed set in
traps.c).
Then we probably shouldn't set VPMU_CPU_HAS_DS for PV guests.
