Re: [Xen-devel] will this clever plan work?

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

We have plans to support efficient replication of filesystem snapshots
amongst multiple VMs, which will support the kind of thing you want to
do (push a given OS + app setup to multiple VMs, and have their writes
go to a 'private version' of the filesystem). It'll probably be a
month or two before anything gets checked in though. :-)
