This one is probably failing because VMCLEAR is being executed from the wrong CPU (actually the VMCS is active on another CPU). That failure type isn't documented, but it would make sense. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
