Considering the fact that both Ubuntu and Elementary require SSE to
boot, I'd wait to get decoding fixed. I wrote a test kernel module that
reliably reproduces your issue on qemu edu device. Whenever QEMU prints

Thanks for helping Roman, so I take it my options at this point are wait
for VMEXIT to be implemented or try to find a linux distro that doesn't
require SSE?

I have tried to run the OS and I can confirm that some instructions that
require VMEXIT are not implemented. In your case that's 0F7F or MOVQ
(mem from mmxreg) from MMX. In my case that's 0F11 or MOVUPS(xmmreg1 to
mem) from SSE.
I'd recommend you to run -cpu host,-mmx,-sse for a while, but the ker

And I've checked your command, no issues.
Could you please try to install qemu from my tap and check if it's gone?
