Another interesting find:

So, about this LWP thing, I've found this: https://bugzilla.kernel.org/show_bug.cgi?id=216211 Apparently, it's a known issue on some (Bulldozer/Fam15h) AMD CPUs, with some microcodes. Boris (Cc-ing him) is on the case, AFAICT. If/when a fix comes out, we probably should consider backporting it, but I guess this will be taken care of by the kernel team, as it's not at all a virt-related issue, and as we see in that bug, it causes issues on baremetal as well. Basically, it's possible that this could be the cause of, or that it plays a role in, this crash, and we probably want it fixed anyway, but the key point here is to stop using host-passthrough for VMs that needs to be migrated. -- You are receiving this mail because: You are on the CC list for the bug.
