Well, unless the processor doesn't support the instruction, but you find that out from EFLAGS.What does vmx_vmexit_do_cpuid() do then? I doubt there are many VMX-capable CPUs without cpuid(). :-) Yes, you can make cpuid trap to the hypervisor if running an hvm guest. But that's quite different from a guest-visible trap or fault. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
