Subject: [PATCH 0/3] Few nSVM bugfixes
Date: Thu, 27 Aug 2020 19:27:17 +0300 [thread overview]
Message-ID: <20200827162720.278690-1-mlevitsk@redhat.com> (raw)
This patch series contains few nested SVM fixes from
testing I did this weekend.
Patch #1 fixes issue where we were setting the GIF (global interrupt flag)
on first nested VMexit, after migration thus making the nested guest crash
from unexpected interrupts.
Patch #2 is my observation that we never setup nesed msr bitmap on nested
state load after migration.
Patch #3 was 'migrated' ;-) from my other patch series to make it smaller,
which is about more strict checks when we about to return to a nested guest,
from SMM.
Best regards,
Maxim Levitsky
