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

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

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"
I’m using an AC922 machine.
In fact I can boot the VMs with pseries-rhel7.6.0 but not with pseries-rhel7.6.0-sxxm; how
do you made pseries-rhel7.6.0-sxxm works on 4.3 release?
