[Xen-devel] HAP Failure with 64Bit Windows 2003

["Huang2, Wei" <Wei.Huang2@xxxxxxx>]

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);
