In my view your problem is that you did not leave any physical memory left for the host system. Maybe .5 GB for the host is OK, if you do not start the GUI software in that machine, and 1.75 GB for each VM may work. But you definitely need to have physical RAM for the host system left. It may have to do, as someone suggested, with your guests trying to allocate and use all assigned physical memory, than definitely your host will be trashing. -- vr.gr.
