I think the goal is to have the VM virtual disks on the shared drive and have
some means of preventing the same VM getting instantiated on multiple
systems - whether using a single shared config, or a copy of the config on
each box - by using a lock file.
This would be a useful feature, given that multiple VMs accidentally sharing a
vdisk is going to corrupt it in short order.
Cheers,
Mark
