a) Add a modprobe.d entry to add the ignore_msrs options to kvm, ex:

# cat /etc/modprobe.d/local.conf
options kvm ignore_msrs=1

b) Hiding kvm is not enough, you also need to mask hyper-v extensions to
avoid a code43.  Add within the <hyperv> section:

<vendor_id state='on' value='0123456789ab'/>

(or some other random 12-char string)
