Description Joey Boggs 2011-10-07 03:17:56 UTC 
I'm trying to install grub2 from a livecd to a livecd based disk install for ovirt-node(upstream for RHEV-H).

disk is setup as
/dev/sda1 ext2 fs Labeled (RootBackup)
/dev/sda2 ext2 fs Labeled (Root)
/dev/sda3 (LVM partition)

/dev/sda2 | /dev/mapper/0QEMU_QEMU_HARDDISK_drive-scsi0-0-0p2 mounted to /liveos inside the livecd image

For this to work normally with F14 and below installs we create a custom grub.conf then run through grub setup to install to the MBR and copy stage1/1.5/2 files over to /liveos.

With Fedora 16 going with grub2 we're trying to get it working on that now and just can't get grub2-install to find the right disk. All configurations have been generated with grub tools and not our tools.

device.map

From /liveos/grub2/device.map: (generated during grub2-install)
(hd0)	/dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi0-0-0

Contents of /liveos
