Thanks for the feedback so there must be something wrong with my distro, which is helpful to know! :)

Anyway, I am now having issues with Qemu refusing to run due to RMA vs VRMA:

I have 512MB <memory> defined but the relevant sections of the XML (I think are):

My guess would be there is something wrong with the VM config, like 4K vs 64k page size (we are 64k only), minimum CPU level in the kernel, things like that.

kth5:
Yes, I switched to a 64K page size kernel again and was able to start the VMs, yet no change. Steal time still there :(
