This is a known limitation... :-(
... what has the existence or otherwise of /dev/sda1 on the
xen master machine got to do with the guest OSes?
In order to create the guest, Xend needs to look up the major / minor for
the device name in the guest you specified. It has to do this on dom0's
filesystem, so if there isn't a /dev/sda1 there it'll fail.
The current workaround is to specify the device number explicitly (e.g.
phy:0801 should work for /dev/sda1).
The long-term fix would be to include a table for Xend to generate device
numbers from, thus eliminating the dependency on these nodes existing in
dom0.
HTH,
Mark
to "fix" this problem, you must cp -aux /.dev/sd* /dev.
