> What happens if it is disabled and we ignore the MSR? Does > everything just work, or does, for example, the write to > EFER.SVME fault? We experienced a #GP during hv boot setting EFER.SVME. So, the hv never came up. Should also get a #UD if try to execute one of the AMD-V instructions first. > Does this new MSR have a name? VM_CR (Virtual Machine Control Register in BKDG to be out in public spec soon) --Tom _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
