Bug Description
[Impact]
Xen guests may hang during resume after a migration or suspend. The predominately affects HVM guests.
[Test Case]
Create a Xen guest and attempt to migrate or save/restore (suspend/resume) hundreds of times.
[Fix]
The following upstream commits (tagged for stable) fix the hangs.
"x86/xen: resume timer irqs early"
https:/
and
"xen/manage: Always freeze/thaw processes when suspend/resuming"
https:/
Both are clean cherry-picks.
