RE: [Xen-users] boot a existing windows in hvm domain

["Artur Linhart - Linux communication" <AL.LINUX@xxxxxxxxxxx>]

Hello,

        Why is it necessary to have a read-write access from windows onto
disk with linux?
        If this should be only from the reason the windows OS is installed
on "disk D:", You can just emulate the "disk C:" by some dummy file...
        At least You could use the linux disk onto DomU as read-only... If
some file transfers are needed, this can be done via some network services
like samba or ftp between Dom0 and DomU...

        With regards, Archie

Yes, it's possible. I have the same configuration, except I have Xen
on /dev/sda and Win on /dev/hda, and I use Xen 3.0.4.

I use this configuration:

disk = [ 'phy:/dev/sda,ioemu:hda,w', 'phy:/dev/hda,ioemu:hdb,w' ]

together with the grub mapping options (which you need anyway to boot
Windows normally if it isn't on /dev/hda); when I boot Windows as domU
I must be careful to select the "Windows XP" choice on grub menu,
otherwise I could destroy both Xen and Windows.
See my old post here:
http://lists.xensource.com/archives/html/xen-users/2007-02/msg00822.html

I suppose there are better and less risky solutions, but I didn't get
deeper since I use it occasionally, and this solution suffices for my
needs.

Bye
