Xen project Mailing List

Hello list,

I'm running AMD Ryzen 3600 processor. L0 is Ubuntu 18.04 Kernel 5.2.7

L1 is Fedora 29 Kernel 5.1.21 - L2 is Windows 7. I'm using host-passthrough for L1.

Compiled against library: libvirt 5.6.0
Using library: libvirt 5.6.0
Using API: Xen 5.6.0
Running hypervisor: Xen 4.12.0

I seem to hit a snag after I try start a VM (creation with pause works fine). Domain-0 is running no problem.. I've also tried this on Xen 4.9, didn't have the errors logging, but same kind of behaviour.

Any suggestions?

Thank you,

Travis
