Subject: TSC deadline timer in guests vs. migration?
Date: Mon, 4 Jul 2016 13:01:42 +0200 [thread overview]
Message-ID: <759376f0-e0bf-e53a-99e4-598bf14547e3@redhat.com> (raw)
Can bad things happen if a guest using the TSC deadline timer is
migrated? The guest doesn't re-calibrate the TSC after migration, and
the TSC frequency can and will change unless your data center is
perfectly homogeneous.
What do you think?
Paolo
