[PATCH 0/3] KVM: VMX: fix handling inv{ept,vpid} and nested RHEL6 KVM

From: Paolo Bonzini
Date: Fri Mar 18 2016 - 12:09:54 EST

Patches 1 and 2 fix two cases where a guest could hang at 100% CPU
due to mis-emulation of a failing invept or invvpid.

Patch 3 works around a bug in RHEL6 KVM, which is exposed by nested
VPID support; RHEL6 KVM uses single-context invvpid unconditionally,
but until now KVM did not provide it.


Paolo Bonzini (3):
KVM: VMX: avoid guest hang on invalid invept instruction
KVM: VMX: avoid guest hang on invalid invvpid instruction
KVM: VMX: fix nested vpid for old KVM guests
