Hello,
Well I have successfully gotten Windows XP Pro to run under XEN using
Intel''s VT technology. However, I can only have this happen when using
a
dedicated partition filesystem. If I try to let the guest OS have a LVM
partition or a file backed partition nothing happens.
When trying to use a LVM partition my computer locks up. When trying to use
a file backed partition I get this error: "Error: Device 768 (vbd) could
not
be connected. Backend device not found." Does any one know what causes
these things to happen? I am using xen-3.0.2.
Here is my config file for the file backed partition:
