For a conference next month I have the desire to run four VMs with a total memory allocation of 7GB, on my Win7 corporate laptop with 6GB of RAM. The run although slowly, might be better described as not snappy. One of the VMs is a SAN simulator, which is adding a chunk of IO to the disk, so off loading the RAM over commit to SD/USB would be an attractive option.

More RAM and SSD would be idea, but not something I can justify for one conference...
