Hi Richie,

Well no LVM on the DomU, kernel just trying to look for vg0 which is present on Dom0 but not DomU, tried omitting the lvm modules from being added to initrd image but it still tries to load a non-existent vg.

Also I wanted to point out that I'm creating my initrd.img from my running Dom0 kernel which is working good but when I try to boot a DomU with it and the custom initrd.img I get the mentioned error.

Thank you for your quick replies guys.

I looked at your output and don't see indication, just before the mount root attempt, that there is a drive available? For example on my domU boot under a Xenified kernel i see "[ 1.236643] blkfront: xvda: barriers enabled" ahead of the root mount. I would think you should see some indication that a drive was detected. Do you think it worth checking your initrd image? Something like "zcat /boot/initrd.img-$(uname -r) | cpio -it | grep xen"

Otherwise nothing else is coming to mind.
