there still has to be a vnc*server* somewhere, in our case
every time you start the vnc console (for host and container) from the 
web, we start a new (temporary) vnc server that connects to a virtual 
tty (and in case of container connects/creates a dtach session)

in qemu it is different, here the qemu process itself has a persistent 
vncserver to which we connect (this is outside of the guest)

you could of course connect to a ikvm supplied by your server directly,
most server-grade mainboards have such a feature (e.g. in the ipmi, 
idrac, hp ilo, etc)

it is technically possible to have the host shell also start
a dtach session, but i am not sure if we want this? what do my 
colleagues say to this?
