Are u using para or HVM domain ?
I think, In case of HVM u cant attach a disk partition. U have to attach the full disk.

But in case of para it should work fine.
What your #cat /proc/partition is showing.

Yes. In dom0:

sirius:~# xm block-list 5
Vdev  BE handle state evt-ch ring-ref BE-path
771    0    0     4      6      8     /local/domain/0/backend/vbd/5/771
770    0    0     4      7      9     /local/domain/0/backend/vbd/5/770
769    0    0     4      8      10    /local/domain/0/backend/vbd/5/769

sirius:~# xm block-attach 5 phy:/dev/vm/ws1.space /dev/hda4 w
sirius:~# xm block-list 5
Vdev  BE handle state evt-ch ring-ref BE-path
771    0    0     4      6      8     /local/domain/0/backend/vbd/5/771
770    0    0     4      7      9     /local/domain/0/backend/vbd/5/770
769    0    0     4      8      10    /local/domain/0/backend/vbd/5/769
772    0    0     4      10     643   /local/domain/0/backend/vbd/5/772

Inside domU:

ws1:/dev# mkfs.reiserfs /dev/hda [tab][tab]
hda1  hda2  hda3

The domU is Debian GNU/Linux Sarge. It's necessary to do something more
inside domU?

Thanks for you answer.

Regards,
Daniel
