Re: [Xen-users] Windows 7 as guest on a physikal disk


I used dd to copy the physical device to a linux file.


Hi Ken,

thanks for the reply, I want to try that. How did you copy
the Windows from disk to file? Did you make a raw copy
using 'dd' or did you copy the files using 'cp' on the loop-mounted
file system?

Quoting Jens Krause <jens.krause@xxxxxxxx>:


I have an installed Windows 7 on one partition
and running Debain Squeeze on the other. Both are 64 bit.
I want to use Xen to run Windows as virtual guest from
a physical disk. Once I get this working the Window will
never be booted directly.

When I try to create the virtual machine by
"xm create -c win.xen"
it hangs.

The versions I use
Xen 4.0.1-4
Kernel 2.6.32-5-xen-amd64

I believe with the version of Xen (or maybe the Linux OS), there was an issue with physical device blocking.

I had a similar problem with Windows 2008.

I resolved the problem for my situation be simply creating the OS as a file, mounting the device under Linux, then using the GPLPV drivers in Windows to achieve decent disk throughput for the guest OS.
