-Subject: [PATCH] watchdog: Disable watchdog on virtual machines.
-
-For various reasons, VMs seem to trigger the soft lockup detector a lot,
-in cases where it's just not possible for a lockup to occur.
-(Example: https://bugzilla.redhat.com/show_bug.cgi?id=971139)
-
-In some cases it seems that the host just never scheduled the app running
-the VM for a very long time (Could be the host was under heavy load).
-
-Just disable the detector on VMs.
-
-Bugzilla: 971139
-Upstream-status: Fedora mustard for now
