The domain0 filesystem is /dev/hda1
virtual domain 1 is /dev/hda5

so it's no shared device. domain1 has /dev/hda5 all for it self.
i'm not doing anything with ramdevices either.

domain0:
root@xeno1:~# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda1              7567600   1447756   5729224  21% /

swap device:


domain1:
root@xeno2:~# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda5              7567600   1573692   5603288  22% /


my uneducated guess was that it was a problem with swap devices.
my old setup was domain0 /dev/hda2 as a swap device,
domain1 no swap device, but i tried domain1 /swapfile (150) mb file
created with dd if=/dev/zero of=/swapfile, and mkswap /swapfile,
sync, sync , swapon /swapfile  .... but that didn't work either.

current setup swapfiles:
---------------- domain1
root@xeno2:~# cat /proc/swaps
Filename                        Type            Size    Used    Priority
/swapfile                       file            141788  0       -1
----------------- domain0
root@xeno1:~# cat /proc/swaps
Filename                        Type            Size    Used    Priority
/dev/hda2                       partition       586144  0       -1
