When selecting what to boot, append the option to the kernel options (-b for emergency boot, 1 or s for single user mode, init=/bin/bash to use bash as init). In grub, you can edit entries with key 'e', and append directly (if not booting Xen) with key 'a'. > > > Seems to be OK.

The disks created under RHEL 5/Centos 5/Fedora 7 have partitions inside, you'll have to use kpartx to create local partitions pointing to the correct areas in the image. kpartx -va /dev/mapper/... should do that, see the manual page for more details (man kpartx). -- lfr 0/0 -------------- next part -------------- A non-text attachment was scrubbed...
