Xen users - Jun 2008 - maximum lun size of a disk in a domU

Hi all,

I''m trying to figure out, whether there is a limit of the LUN size for
a
virtual harddisk used in Xen domU''s. 
e.g. I setup a domU to use /dev/mapper/large-disk as a disk. Is there a 
maximum size of the disk that can be used in the virtual machine?

As far as I know, I cannot use LUN''s larger than 2 TB in vmware. In 
case /dev/mapper/large-disk would be a 3 TB sized disk, then the virtual 
system would only be able to use 3 TB of it. This is a limitation that comes 
from vmware, and therefore has nothing to do with the capabilities of the 
virtual operating system. 
therefore I''m wondering whether there exists a similar limit for xen,
and if
so, what is the limit.

kind regards
Sebastian
