Ovirt 4.3 Alpha AMD 2970WX Windows VM creation and NUMA
Not sure if Users is the best place for this as Im using 4.3 to test support for my AMD 2970WX Threadripper but While trying to setup a Windows VM, it fails. I have a working CentOS 7 running. Heres what I get when I try to startup the VM. VM Windows-Darin is down with error. Exit message: internal error: process exited while connecting to monitor: WARNING: Image format was not specified for '/dev/sg0' and probing guessed raw. Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted. Specify the 'raw' format explicitly to remove the restrictions. 2018-12-02T18:43:05.358741Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: CPU 10 [socket-id: 10, core-id: 0, thread-id: 0], CPU 11 [socket-id: 11, core-id: 0, thread-id: 0], CPU 12 [socket-id: 12, core-id: 0, thread-id: 0], CPU 13 [socket-id: 13, core-id: 0, thread-id: 0], CPU 14 [socket-id: 14, core-id: 0, thread-id: 0], CPU 15 [socket-id: 15, core-id: 0, thread-id: 0] 2018-12-02T18:43:05.358791Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future 2018-12-02T18:43:05.359052Z qemu-kvm: can't apply global EPYC-x86_64-cpu.hv-synic=on: Property '.hv-synic' not found. NUMA doesnt seem to resolve the issue any even if I set NUMA to be 1 and place it on a NUMA that has 12 cores and 64GB ram. I also dont fully understand NUMA because it creates 4 NUMA sockets even though technically there should be 2 correct? I dont get how NUMA is setup, but either way it doesnt help resolve any issues.

EPYC-x86_64-cpu.hv-synic=on: Property '.hv-synic' not found. is hv-synic a typo somewhere? would imagine that is supposed to be hv-sync?
That was my thought too, I'll do some investigating. Not 100% sure where to look atm.
I went ahead and submitted a bug report. I cannot find the typo anywhere.

https://bugzilla.redhat.com/show_bug.cgi?id=1655340 is been marked as a duplicateof bug: https://bugzilla.redhat.com/show_bug.cgi?id=1644693 which pretty much from my understanding stated that they require qemu and kernel for new hyperv flags On Thu, Dec 13, 2018 at 10:10 AM Sandro Bonazzola <sbonazzo@redhat.com> wrote:

I cant get any further though for some reason. I think its with qemu. I can get a VM up to install the OS by selecting somethign other than Windows for the VM type as specified as a possible workaround. But as Windows boot ISO does its thing, it throws a thread error. I can get the error later today if needed. I just been patiently waiting for 4.3 to become more developed so I can use my hardware.
