[gentoo-user] QEMU on a partition

[Helmut Jarausch]

Hi,

I'd like to install a second Gentoo system on a partition by running
QEMU using that partition (directly) - this is to create and update a  
Gentoo
system with different CFLAGS (for an older machine).
Having no experience in such setups my initial problem is how to
install grub2 on that partition (only). I don't want to modify the MBR
of the whole drive containing that partition.

Is is possible?

Many thanks for some hints or pointers,
Helmut
