I tried to install with "grub-install" grub for guest os (which is debian) from host (centos). Tried with chroot, tried with deboostrap, tried with netinstaller. Centos is running on two raid hdd's,under LVM. Lvm volumes are created everything is formated and works. Only bootloader problem left.
Netinstaller just throws me a window with error that grub can't be installed, debootstrap instructions is not clear for me in here, grub-install doesn't work in chroot, and out of chroot (grub-install /dev/mylvm/partition)
Please can somebody write how to install grub for domU (guest) os from centos?
Edit: For feedback: in domU configuration I set bootloader for pygrub. Then it started ok. Still haven't figured out how to make a successful installation from debian install image.
