Subject: [PATCH 6/7 v7] nSVM: Define an exit code to reflect consistency check failure
Date: Mon, 12 Apr 2021 17:56:10 -0400	[thread overview]
Message-ID: <20210412215611.110095-7-krish.sadhukhan@oracle.com> (raw)
In-Reply-To: <20210412215611.110095-1-krish.sadhukhan@oracle.com>

Define an exit code that reflects failures in consistency checking during
VMRUN. KVM sets bit 63 in EXIT CODE when it detects invalid guest state
during VMRUN consistency checking.
