Hi,
i am trying to create a bootable vm using grub2. Here are the steps i tried:
1. creating a logical volume using lvcreate
2. creating a partition-table with one ext partition inside the logical
volume:
#parted -s /dev/${VGNAME}/${LVNAME} unit GB mklabel msdos mkpart primary
ext2 0 ${LVSIZE}
4. kpartx -a /dev/${VGNAME}/${LVNAME}
kpartx generates an extra device-node for the partition. I used this one
to create a ext4 fs on it, mounted it and deboostraped a basic debian
system to it. Here is where the problem starts. I don't know how to
install grub2 to the lvm device-node from the host. As a host system i
used archlinux. I tried a lot ways to get grub to work.
For example i created a device.map like this:
(hd0) /dev/mapper/vg-debianvm
(hd0,1) /dev/mapper/vg-debianvm1
and used it in combination with grub-install wich failed.
My question is, whats the right way to install grub2 to the lvm device?
Or is there a way to install grub2 to a logical volume without a
partition-table (/dev/vg/debianvm)? Do i have to chroot to the system to
install grub or is there a way to install it from the host?
