[Opensim-users] OpenSim and Virtual Machines

[R.Gunther]

Only tried opensim in virtualbox (on windows :O ) with opensuse as guest.
But the biggest problem i see is the hdd speed. maby not enough cpu 
resources. assigned 2-3 cores.
But it where a bit more laggy. but linux is not the best choice for 
opensim anyway, so it maby could be mono to.
