At that level of description Intel VT is almost identical to AMD SVM. The VMCB is called VMCS and the instructions have different names (and slightly different usage conventions) but there aren't any significant differences really. Most of the AMD/Intel-specific code for HVM is decoding exits from the guest back to Xen to work out what happened (the reason codes are all highly vendor-specific). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
