RE: [Xen-users] Windows uder XEN doesn't boot...

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

Hello,

        The boot from /dev/sda2 will not be possible, because it is the
partition and not the physical disk - if You pass just the /dev/sda2 to xen
DomU as a virtual disk, it expects to be really a physical disk, looks for
partition table etc. which is not there, because there are the data of the
single already formatted partition. So, from this reason I think this is not
even theoretically possible.

        The idea with the HW profile should theoretically work, but I could
not try it because the above problem... 

        I had the exact same situation like You describe here on my
notebook, but I could not get it running - so, till to day I have to reboot
if I want to work with windows... 

        With best regards

                Archie

Linux is on /dev/sda5 and swap is on /dev/sda6

Windows is on /dev/sda2

so maybe it will be possible to boot only from /dev/sda2?

please notice that I can boot second time from /dev/sda5 and linux
is starting again in the XEN window.

maybe it will be possible to create second hardware profile and add
XEN drivers....?
