[solved] Xen - Can't boot domU: could not read boot disk

joshdmiller · 2013-09-22 07:43:18

I installed Xen and seem to have everything working. I set up an HVM domU with some physical disks and an arch iso and went through the install as normal. After installation, I removed the ISO from the config and launched it again, but it won't boot. The Xen bios gives this:

Booting from hard disk...
Boot from hard disk failed: could not read the boot disk

I've tried several times to get this right, but it's always the same result. As with a normal arch installation:

# grub-install --recheck /dev/sda
# grub-mkconfig -o /boot/grub/grub.cfg

Both give the expected outcome and report no errors, though clearly something is not right.

How do I set up correct booting for a domU? Thanks!

Alright, solved! As it turns out, I needed to map physical devices as "/dev/xvda" rather than "/dev/sda". This makes perfect sense, but the wiki doesn't indicate this requirement.
