Re: [Xen-users] How do unmodified guests work with Xen?

[<pjn@xxxxxxxxxxxx>]

I am also interested in how this process is accomplished. I understand that 
headless
installs of w3k server are possible on equipment that supports EMS but am
confounded by how hardware device driver support is provided in Xen at the
moment for this operating system?

See http://support.microsoft.com/default.aspx?scid=kb;en-us;815273

Any words of wisdom from the enlightened would be most appreciated.

Regards

Petar
