Just added the full paths to the lvms. No difference made. should i also change
root = "/dev/sda1 ro" to something like
root = "xvda ro" ?

You might have better luck using the full path to the /dev files here...
disk = [ 'phy:/dev/xenLabs/etch_lmv,xvda1,w', 'phy:/dev/xenLabs/
etch_swap,xvda2,w' ]
I switched sdaN to xvdaN, though it shouldn't matter which you use.
I am using LVM on dom0 to manage domU's disks with no problems.
