Memory bandwidth would limit the performance unless your VMs were running something with a very small memory footprint, about 160 megabytes per instance.

Having said that, I've used Unix workstations with less RAM attached than that through much less than 7GBps worth of bus...

Phi's memory bandwidth is very high but its memory capacity is very low (a normal Xeon can drive ~192 GB cheaply).
