Andreas,

The program that created the disk image seems confused, but it worked for creating a VM for FC11.
Windows install seems to run fine, until wanting to boot from the drive it created.
I don't know what creates the drive image and geometry, but it is broken.

I think this is what I used to create the VM, but I have messed around with so many configurations and methods, I'm not sure what is what anymore.

virt-install --connect qemu:///system -n w7 -r 2048 --vcpus=2 \
--disk path=/vm/w7.img,size=20,sparse=false,format=qcow2 \
-c /vm/w7cd.iso --vnc --noautoconsole \
--os-type windows --os-variant win7 --accelerate --network=bridge:br0 --hvm

How many thousands of people have struggled with this and also got nowhere?
It just looks like the virt-install developers have not tasted their own dogfood!

LVM is supposed to be easy - just select vm image and boot, but the more
I read about VMs, kvm, qemu, virtualbox, virsh etc, the more confused I get on how they
relate to each other.
