Subject: [PATCH 0/4] Avoid soft lockup message when KVM is stopped by host
Date: Mon, 29 Aug 2011 23:27:11 +0000 [thread overview]
Message-ID: <1314660435-23293-1-git-send-email-emunson@mgebm.net> (raw)
Currently, when qemu stops a guest kernel that guest will issue a soft lockup
message when it resumes. This set provides the ability for qemu to comminucate
to the guest that it has been stopped. When the guest hits the watchdog on
resume it will check if it was suspended before issuing the warning.
Eric B Munson (4):
Add flag to indicate that a vm was stopped by the host
Add functions to check if the host has stopped the vm
Add generic stubs for kvm stop check functions
Add check for suspended vm in softlockup detector
