Hi guys, I was lately thinking around jail hot-migration feature where one jail could be moved from one host to another without shutting it down, something like vmotion in VMware world.
The storage layer should be easy with zfs send and receive or some form of shared storage. The tricky part would be a memory copy from one node to another and also the CPU handling. Anyone has an idea how this could be achieved? I guess it would require a kernel module which could take care of memory reservations and a daemon to copy and incrementally sync the jails memory across. Then also there is the CPU problem.. Sounds like a fair amount of work and development. All comments are welcomed!
