Hi,

I've a quad-core x86_64 machine (Intel Xeon), with sse/mmx support.
However, I want to disable sse/mmx support from HVM guests. How can I
do this? Also, is it reasonable to expect illegal instruction fault in
non-root VMX mode if a guest VM runs an application with sse/mmx
instructions?

Thanks,
Ashish
