Hi Avi, Marcelo,
here is a set of patches which fix problems in kvm-amd. Patch 1 fixes a
stupid problem with the event-reinjection introduced by me in my
previous patchset. Patch 2 was a helper to find the bug patch 3 fixes.
I kept it in the patchset because it may be helpful in the future to
debug other problems too. Patch 3 is the most important fix because it
makes kvm-amd on 32 bit hosts work again. Without this patch the first
vmrum fails with exit-reason VMEXIT_INVALID. Patch 4 fixes the Xen 4.0
shipped with SLES11 in nested svm. The last patch in this series fixes a
potential l2-guest breakout scenario because it may be possible for the
l2-guest to issue hypercalls directly to the host if the l1-hypervisor
does not intercept VMMCALL.
Thanks,
Joerg
