Hello, I’m trying to run ppc64le VM’s on POWER9 but qemu-kvm fails complaining about NUMA issues:

that is not a line you should be looking at, it’s just a harmless warning.
I suppose it’s the other one, about spectre fixes

VM ppc64le.local.versatushpc.com.br is down with error.

Any idea of what’s happening?

I found some links, but I’m not sure if they are related or not:
https://bugzilla.redhat.com/show_bug.cgi?id=1732726
https://bugzilla.redhat.com/show_bug.cgi?id=1592648

yes, they look relevant if that’s the hw you have. We do use pseries-rhel7.6.0-sxxm machine type in 4.3 (not in 4.4. that would be the preferred solution, to upgrade).
If you don’t care about security you can also modify the machine type per VM (or in engine db for all VMs) to "pseries-rhel7.6.0"

Thanks,
michal

Thanks,
