Subject: [PATCH 10/11] KVM: SVM: Clear exit_info for injected INTR exits
Date: Wed, 24 Feb 2010 18:59:19 +0100 [thread overview]
Message-ID: <1267034360-5907-11-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1267034360-5907-1-git-send-email-joerg.roedel@amd.com>
When injecting an vmexit.intr into the nested hypervisor
there might be leftover values in the exit_info fields.
Clear them to not confuse nested hypervisors.
