[libvirt-users] vm grub errors

Hello, I've set up a kvm host and used virt-install to create a new guest VM installed to logical volumes. It works great! However all subsequent guests I attempt to create the same way refuse to boot. They all get stuck at the grub rescue menu reporting "no such device". I tried installing a new guest and dropping to a shell just before finalizing the installation so I could examine the contents of grub.cfg To my eyes it actually looks just fine. It is referencing the correct virtual drive. Here is a pastebin with a few commands and output I thought might be relevant. http://pastebin.com/GwqbY7X7 Once I finalize the installation the same thing happens. Grub reports the same error. At the grub rescue prompt if I attempt to: ls (hd0,msdos1)/ error: unknown filesystem. In the host I can see that the logical volume where I installed the root partition of the VM above is in fact active. This is exactly the same way I installed the first VM on the same host and that one i still working fine. On a local machine I practiced setting up multiple VM's this way and had no problem so it's not an error I can reproduce anywhere other than the production server. Can anyone offer ideas of other things I should try or check?
