Small addendum.... :)

- Oracle nicely solved this by having something like
/virtual_machines (ocfs2)
/virtual_machines/templates
/virtual_machines/deployed/
/virtual_machines/deployed/vm001
/virtual_machines/deployed/vm001/OSdisk.img
/virtual_machines/deployed/vm001/Any_Data_disk.img
/virtual_machines/deployed/vm001/vm.cfg

Of course that means you'd not be using LVM.

I'd recommend you move away from virt-manager unless you're really
really focussed on running very few VMs with no VLANs ...
Otherwise you'll end up (manually!) maintaining it's xml configs.
The only thing I ever liked about it is that it reconnects when the VM reboots.

For speeding up the live migration, have a look for the patches called
"vm-migrate-after".
They're supposed to make things a lot faster just never made it into Xen.
