RE: Teleportation requires shared storage

Oh, that would be so painful.
Typical migration time for a VM under VMWare ESX, using shared storage, is under 2 minutes.
Having to rsync even a mere 20gb virtual disk would be incredibly slow, and at some point you'd have to freeze disk I/O for some amount of time. I suppose, in theory, you could snapshot the disk, and mirror the snapshot, while you stream the journal to both the local machine and the remote machine, but just thinking about it gives me a headache.

Seems that the new Teleportation feature requires the source and target machines to have access to shared storage (iSCSI, CIFS/NFS) where the contents of the Virtual Machine are stored.
I'm a little bit disappointed. While shared storage provides for the fastest migration of VMs I was expecting that Virtual Box could send the entire VM (if required) across the network (using rsync, for example).
