x86: fix guest migration after c/s 20892:d311d1efc25e
|
|
|
|
Guests would not manage to run successfully after being migrated to a
|
|
host having sufficiently much more memory than the host they were
|
|
originally started on.
|
|
|
|
Subsequently the plan is to re-enable the changes behavior under the
|
|
control of a guest kernel announced feature flag.
