I have two filesystem images that I built: root and /mnt and with a guest m= enu.lst that uses UUID I am able to create a running xen domain using eithe= r a normal 'xm' config or a 'pygrub' bootloader config.

The g= uest menu.lst uses 'uuid' rather than 'root' and whenever I try to create t= he domain using 'pv-grub' it always drops me to a 'grubdom' prompt. I= n grubdom if I just add a line 'root=3D/dev/xvda1' then it will boot fine.&= nbsp; I cannot test 'uuid' in grubdom because it does not recognize the 'uu= id' command.

Can anyone see what is missing? I thought UUID should work with p= v-grub but it is failing for me.
