Hi, In the function vmx_do_cpuid() of xen 4.0.1, it calls vmx_cpuid_intercept() which deal with the case where eax is 0x80000001 only, much less than the cases in vmx_do_cpuid() of xen 3.1.0. Does that mean fewer instructions is monitored in xen 4.0.1? Why? Thank you. Sincerely, K.C. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
