[fedora-virt] P2V and grub bootloader

[Richard W.M. Jones]

Here's an example where I've used a separate /boot partition and root
is on an LV:

-------------------------------------------------- /tmp/test.sh 
#!/bin/sh -

guestfish <<EOF
alloc /tmp/test.img 500MB
run
sfdisk /dev/sda 0 0 0 ",10 ,"

echo Size of /dev/sda1:
blockdev-getsize64 /dev/sda1
echo Size of /dev/sda2:
blockdev-getsize64 /dev/sda2

mkfs ext2 /dev/sda1
pvcreate /dev/sda2
vgcreate VG /dev/sda2
lvcreate LV VG 400M
mkfs ext2 /dev/VG/LV

mount /dev/VG/LV /
mkdir /boot
mount /dev/sda1 /boot

grub-install / /dev/sda

echo Grub is installed on /dev/sda
ll /boot
ll /boot/grub
EOF

ls -l /tmp/test.img
file /tmp/test.img
--------------------------------------------------

$ time /tmp/test.sh
