Subject: s390x: Add unpack facility feature to GA1
|
|
|
|
Git-commit: 3034eaac3b2970ba85a1d77814ceef1352d05357
|
|
References: bsc#1167075
|
|
|
|
The unpack facility is an indication that diagnose 308 subcodes 8-10
|
|
are available to the guest. That means, that the guest can put itself
|
|
into protected mode.
|
|
|
|
Once it is in protected mode, the hardware stops any attempt of VM
|
|
introspection by the hypervisor.
|
|
|
|
Some features are currently not supported in protected mode:
|
|
* vfio devices
|
|
* Migration
|
|
* Huge page backings
|
