[Xen-users] 64bit Windows Guest Blue Screens on install

["Garreth McDaid" <garreth.mcdaid@xxxxxxxxxx>]

Hi,

We have a XEN Server running on CentOS 5.5. Details are given below.

We have several guest OSs running, but we are unable to install Windows  
2008 R2. We can install any 32-bit version of Windows (Vista, 7 etc).
When we attempt the install, the process starts as normal, but when the  
process finishes loading files from the media (just before it enters GUI  
mode), it Blue Screens with a STOP message.
The XEN install is the most recent version that is available from the  
CentOS repos. I've tried installing directly from DVD, and from an ISO  
file. I've also verified the installation media works on a separate system.
Could anyone offer any advise? I've read that a compile-from-source may be  
required, but I'd really like to avoid that if possible, primarily because  
a V4 pre-compiled kernel from CentOS isn't available, and I'd have to  
compile a kernel for what is one of our more critical systems.

XEN
