Tim,
I found that your
small patch (changeset 15291) caused failure with Windows 2003 64Bit and Vista
64Bit under nested paging. It turned out that intercepting CR0 read should not
be disabled. Please see the change below. Other guests seem running
well.
Thanks,
-Wei

Replace
vmcb->cr_intercepts &=
~(CR_INTERCEPT_CR0_READ
|CR_INTERCEPT_CR3_READ
|CR_INTERCEPT_CR4_READ); with
vmcb->cr_intercepts &=
~(CR_INTERCEPT_CR3_READ
|CR_INTERCEPT_CR4_READ); _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
