The problem is that xsaves is not supported on all intel/amd cpu, 

older model don't seem to support xsaves too  (intel only since
sandybridge , amd since epyc v1)
https://github.com/qemu/qemu/blob/master/target/i386/cpu.c#L3050



but also newer model depending of firmware revision

"target/i386: EPYC-Rome model without XSAVES"
