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

and my created dir is gone...

where do i look for an answer for this problem???

(which info do you need to help me out, and i'll post it)

Perhaps you could send the output of 'df', both from domain 0 and from
your new domain.

Is the filesystem shared with some other domain? It is not safe to
share a filesystem unless all sharing domains mount it read-only.

If this isn't the problem, then is the filesystem on a ram disk? That
ought not to cause this problem though...
