Can you tell how you reproduce it? I am following the steps you told
me previously, but I cannot reproduce it with this fixing.
Any update on this?
Ping again.
I will have a look at this issue next week.
Btw., Andrew Cooper hinted at the possibility of this series


(particularly patch 2) having an effect on migration problems
between APICV-capable and -incapable systems, i.e. perhaps
worth a try in this context too.


The issue XenServer observes is that problems occur even when migrating between two identical machines, one with APICV enabled, and one disabled.

Given the now-discovered issues with Xen's x2apic handling, it is entirely possible that the differences between the emulated and real APICs was enough to cause issues. And yet, it could be a mixture of all of the issues identified so far.
