How will it behave when:
- VM is being snapshotted?
- VM is being migrated?
- VM is suspended?
- VM is being (cold)rebooted?
At least for last two I suppose the serial console session will be
interrupted.
VMWare uses extended communication to inform virtual serial port
concentrator about various action of a VM, thus "proxy" doesn't drop
serial connections.
there is no reason why the proxy cannot retry for a while and reconnect to the new
instance.
however this will not be provided at first nor it is that important as client can always
implement reconnect at its side, and handle this just like any other network failure.
