Its not terribly consistent when the hang happens, but every HVM domain will eventually hang the system if left running long enough. Sometimes the system hang immediately, sometimes after 20 minutes. I disabled all power management (turned off PowerNow!) and that actually seems to make it freeze faster. So I'm running with the smallest HVM configuration possible using xl as below

name = 'test'

memory = 1024

builder = 'hvm'

Since the system just hangs I get no errors messages or anything. Has anybody successfully ran HVM on a A10 AMD CPU? Its one of the new Richland APUs. Can anybody point me to some info on how to debug this issue? FWIW, KVM runs fine.

Thanks,

Darren

Can you boot xen with the additional options "loglvl=all iommu=debug,verbose apic_verbosity=debug cpuinfo" and attach Xen's dmeg `xl dmesg` and dom0's `dmesg` as a starting point.

I have to say that we have never countered symptoms like this when testing XenServer, but on the other hand, we don't appear to have any similar hardware.

Are you able to get a serial console attached?
