Subject: [PATCH 1/4 V10] Add flag to indicate that a vm was stopped by the host
Date: Tue, 17 Jan 2012 13:40:38 -0500 [thread overview]
Message-ID: <1326825641-15765-2-git-send-email-emunson@mgebm.net> (raw)
In-Reply-To: <1326825641-15765-1-git-send-email-emunson@mgebm.net>
This flag will be used to check if the vm was stopped by the host when a soft
lockup was detected. The host will set the flag when it stops the guest. On
resume, the guest will check this flag if a soft lockup is detected and skip
issuing the warning.
