Looking at CR4: 00000000003006f0, it doesn't have OSXSAVE set. I.e., bit
18. And when that bit is not set, VMOVDQA raises an #UD.

And for some reason qemu doesn't like it even if you request that bit with
+osxsave:

warning: host doesn't support requested feature: CPUID.01H:ECX.osxsave [bit 27]

Even though the corresponding bit in CPUID on the host is set:

0x00000001: EAX=0x00800f00, EBX=0x40200800, ECX=0x7ed8320b, EDX=0x178bfbff
						   ^
Paolo, any thoughts?

The OSXSAVE CPUID bit is not set by QEMU, it is set by the OS itself
(indirectly) when it sets CR4.OSXSAVE.  QEMU says it's not available
(probably) because the Opteron_G3 CPU model does not have the 0xD CPUID
leaf.

I think you're using libvirt's "host-model" CPU model.  That model needs
QEMU/libvirt support for each host CPU family, and in general it often
gives rise to bugs such as the one you're reporting,

Change it to host-passthrough, and please send us the output of
/proc/cpuinfo so we can add support for Ryzen in "host-model".

Thanks,

Paolo

Nope:

0x00000000 0x00: eax=0x00000005 ebx=0x68747541 ecx=0x444d4163 edx=0x69746e65
		     ^^^^^^^^^^

highest is 0x5. I'll let Satoru comment on the rest.

Thanks Paolo!

Yes, I used "host-model".

I changed it as you said and my own kernel succeeded to boot, thank you!

It looks like the cause is that AMD has removed TBM instructions
compared to e.g. Piledriver, so libvirt resorts to a much older base
model (thanks to Dave Gilbert for sorting through the list of feature bits).

Can you please run this script:

http://libvirt.org/git/?p=libvirt.git;a=blob_plain;f=tests/cputestdata/cpu-gather.sh;h=83963557ec4075d351be09e17994ac5300bc5d1f;hb=HEAD

and send the output?

Thanks,

Paolo

... and the libvirt people also told me that:

- a more recent QEMU would have enabled CPU leaf 0xD, making it possible
to use AVX inside the guest.

- a more recent libvirt would have used Opteron_G5 as a base instead of
Opteron_G3.

Thanks,
