Comment 6 for bug 610652

I also see this. Have deployed 50 production VMs, it happened approximately 10% of the time.

I'm using KVM with LVM and vm-builder; these options:

vmbuilder kvm ubuntu --hostname=vmbuilt --domain=manc.iws-hosting.co.uk --raw=/dev/svs4/vmbuilt-disk --mem=512 --user=iweb --pass=xxx --rootpass=xxx --cpus=1 --templates=/templates --dest=vmbuilt --ip=192.168.1.201 --mask=255.255.255.0 --gw=192.168.1.182 --dns=193.228.155.86 --rootsize=8192 --swapsize=1024

dd'ing off the first sector of the LV shows that GRUB just isn't present in the MBR and launching a VM just stops with no GRUB messages.
