On a fresh install of W2k8 R2 Enterprise, I see that
/Windows/System32/drivers/Wdf01000.sys and WdfLdr.sys are present and the
version is 1.9.7600.16385. I am assuming this means that KMDF is installed.

After the first gplpv install and before the first reboot, I can see that
there are no exclamation marks in device manager. "Xen Block Device Driver",
"Xen Net Driver" and "Xen PCI Device Driver" are also loaded i.e. they show
up in Device Manager with no exclamation marks.

>What about on the first reboot?

On the first reboot, the answer is same as above except I see an exclamation
mark against the "Intel Bus Master IDE Controller". However, that remains
even after the second reboot.

Thanks,
AP
