Hi everyone,

Even though I have nested virtualization enabled in my Arch Linux system which I use to run OST, vm_run is the first test to fail in 004_basic_sanity (followed by snapshots_merge and suspend_resume_vm).

Can you point me to what I might be missing? I believe I get the same failure even on Fedora.

This is what host0's CPU capabilities look like (vmx is there):

journalctl -b on host0 shows that libvirt complains about NUMA configuration:
