I'm running a ubutnu (12.04) guest under MacOS Maverick. I'm connecting to the guest via ssh in a Mac Terminal window. Oftenly the command line stops responding or responds really slowly. Sometimes it even responds in strange ways like pressing <ENTER> key results in the command line showing the current working DIR. While if I enter commands directly into the VM window everything works normally - no lagging at all.
I've googled and tried many things. I've suspected that it was that the general VM performance wasn't good but it turned out not the case. I've tried all the NIC options in virtualbox network configuration.
I don't know if this matters but the guest was copied from windows 7 - originally it was installed and had been running there for a while.
Anyways here are the specs if it helps:
