Hi all,

I'm currently using Xen 3 with file-backed VBDs and have just setup a
new Xen0 server.  What's the best way of copying the image files across
to the new server (currently stored locally on the old Xen0)?  I want a
copy because I'm duplicating the XenU's.  I've tried scp but the image
files take up their full disk allocation rather than their actual usage
(eg 5GB instead of the 1.1GB actually used).  Would rsync using rsyncd
be better, or NFS?

I'm thinking of using LVM VBDs instead so what would be the best way in
this scenario?

The reason I'm currently using the file-backed VBD's is for the ease of
handling and the fact that the XenU's perform little IO.

If it makes any difference I don't have local access, these are remote
servers but I do have console and PXE boot ability.
