Just as a clarification, as I read the various manuals,
it seems that the key difference is that
the enterprise linux 5.2/xen 3.1.2 (labeled 3.0.3 as it comes from Redhat)
is running libvirt, and my previous setup that I'm trying to
upgrade to that was not.
So does anyone know how to export a single partition to a
libvirt-enabled xen domU that's otherwise installed already, or
how to take a non-libvirt domU with 3 such partitions and turn it
into one that is\

I have some old xen instances which were installed under
Xen 3.1.0 with the following Disk configuration
disk = [ 'phy:LG0/LV11,sda1,w', 'phy:LG0/LV12,sda2,w','phy:LG0/LV13,sda3,w' ]
Each one of these is a single partition, with a single file system.
I am now trying to run redhat/centos/scientific linux 5.2 and convert
these old domU's over.
I run a lot of stuff on redhat/centos/scientific linux but
I have used the virt-manager to install all of them, and they are
all set up using the xvda type file system in which each exported
partition has got a partition table.
disk = [ "phy:/dev/LG0/LV0,xvda,w", "phy:/dev/LG0/LV16,xvdb,w" ]
Is there any way to mountt single partitions
under the new software, if so, how?
I tried to export the three partitions above as xvda,xvdb, xvdc
and change the fstab and the grub information in domU accordingly,
no luck
I also tried to just do things as before with sda1,sda2,sda3,
also no luck.
In all cases I get this error
mount: could not find filesystem '/dev/root'
Setting up other filesystems.

I suppose I could move all existing file systems to new ones
of the new format but would really like to avoid that if I can.
