Subject: [PATCH 1/4 V11] Add flag to indicate that a vm was stopped by the host
Date: Tue, 31 Jan 2012 10:35:29 -0500 [thread overview]
Message-ID: <1328024132-7687-2-git-send-email-emunson@mgebm.net> (raw)
Message-ID: <20120131153529.g3piYSBanFncrT6JmXqUaYQ-li8Gb6Wr1yYdVWXTQqI@z> (raw)
In-Reply-To: <1328024132-7687-1-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.
