s390x/protvirt: allow to IPL secure guests with -no-reboot |
[Impact]
* on s390x the transition from non-secure to secure is a program directed
IPL. IPL "usually" was menat to load a system. Due to that the
-no-reboot option blocks that transition.
* It is required to check the IPL function code and allow this "kind of
IPL" despite -no-reboot being set.
[Test Case]
* Run a s390x protvirt qemu-kvm and add the option -no-reboot
- without the fix this will fail
* Note: We will need IBM to test this for the access to the required
hardware and a secure-execution enabled kernel (as used in the bug
report)
[Regression Potential]
* The change is small and clear, but if anything then IPL actions like
load&reboot should be affected.
[Other Info]
* n/a
