Ie= p I used your last patches, (your website it's at the top of my bookmarks),=

I forgot to mention that I had to make a couple of fix to xen tree, c= ause it
wasn't compiling on my system due to  "error: format not a = string literal

As far as I know those doesn't break anything, but = dont take too seriously,
i'm not an experienced developer :)


= Forgot 2:
Since I'm using an ubuntu kernel, the xen support is not integ= rated, but you
need to add xen modules at your inittrd file. I did this = by adding those:

xen-pciback passthrough=3D1
xen-blkback
xenfs=
xen-netback
pci-stub

to /etc/xen/initramfs-tools/modules and = the issuing update-initramfs.

In the future, I'll try to boot a lin= ux domU, right now I'm still smiling
cause I can fully wipe my Windows i= nstallation from the hard disk. And I'm
sure that in future Win7 will be= supported too.

Thanks again David and everyone,
Ivo
