[Fedora-xen] Installing a different distribution as guest

[Lars Erik Dangvard Jensen]

Hi list

How do I install a different distribution as a guest/domU on Fedora  
core 5 dom0?

I just want to install ubuntu or debian sarge onto a lvm partition.

Is there anyone out there with at working approach?

I've tried a debootstrap for Fedora etc. but I get errors that chroot  
doesn't work.

I've also tried to make a boot partition, but then I get kernel panic.

I use the 64 bit FC5 edition, maybe that's my trouble?

Thanks

Lars
