Install / upgrade fc17 -> fc18 better than I expected

I wanted to try upgrading on a system with multiple boot and root partitions, 
sharing home ans swap.

How I did it:
   I took an fc17 test machine and made a new copy of the disk image
     qemu-img convert f17-work.img f18-base.img
   I made a working copy
     qemu-create -b fc18-base.img fc18-work.img
   I made it bigger
     qemu-img resize f18-work.img +6G

Then I booted:
   qemu-kvm -m 1200 -hda fc18-work.img -cdrom fc18-install.iso -boot d

As I did the install, creating a new partition for boot and one for root(fc18) 
worked finr, the swap was picked up from the LV of fc17.

Then I tried to have the fc17_root mount /fc17/root and the fc17_home LV mount 
on /fc17/root, etc. Nothing complained, but it didn't work.

If there was a way to provide other bootable OS I missed it (it should be 
obvious). So I can't boot fc17, and I can't boot XP. That seems like an issue.

Hope this helps someone. Hypervisor gurus can do this cleverly, I went manual so 
it would work for me.
