Thanks for the data point. I've been putting my data into: https://bugzilla.yoctoproject.org/show_bug.cgi?id=12301 As you can see there, I think there are actually two issues: a) A boot hang around the ..TIMER line where the guest isn't getting timer interupts b) Something which causes the APIC to see "version 0". I applied the 2.11-rc2 upgrade and it seemed to stop the hangs I was seeing with "-no-kvm-irqchip" but doesn't stop the ones I see without that. I am seeing hangs in guests where the version 0 message appears as well as where we see 0x14. The 0x14 versions do boot further into userspace usually. It also seems host hardware specific as I cannot get my local build machine to hang as yet. That could mean its timing or could be cpu revision, I've removed many but not all OS differences :/.
