We are facing an issue with some of our large VM. So far in order to
export Vm without shutting them down, we create snapshots, then export

As this solution works perfectly for small VMs.  For large Vm is does
not as require the same space as the VM itself to create snapshots.
Right now we can not afford to have some much space free, nor we can
stop the VMs.

I wonder is there a solution to just export the skeleton of the VM and
the main vdi.
thus we could recreate the Vm (disaster recovery) and just push the
data back in.

thanks for your help
