The ptcr (partition table control register) is used to store the address
|
|
|
ae23c9 |
and size of the partition table. For nested kvm-hv we have a level 1
|
|
|
ae23c9 |
guest register the location of it's partition table with the hypervisor.
|
|
|
ae23c9 |
Thus to support migration we need to be able to read this out of kvm
|
|
|
ae23c9 |
and restore it post migration.
|
|
|
ae23c9 |
|
|
|
ae23c9 |
Add the one reg id for the ptcr.
