List,

I have yesterday successfully installed Xen 3.0.2 on Ubuntu 6.06 and have
a Ubuntu 6.06 running as guest. I have a couple of questions which is not
clear to me after having read the documentation.

1a. File to partition ?
The guest is stored in a file and not on a partition. Can that be changed
at a later point, perhaps just migrating ?, or do I have to created a new
guest from scratch.

1b. File resizing
As far as I understand it is not possible to extend the size of a
filebased guest OS, is that correct ?

Yes, It`s possible if you use LVM and, for example XFS file system. With LVM you can resize you virtual partition.
With ext3 file system the resize is possible too.

2. Migrating between different host OS
Is is possible to migrate the Ubuntu guest from the Ubuntu host OS to
another host OS say SuSE ?

You need use the same version of XEN in the server host, then you can migrating between different host`s using "xm migrate" command.
