To add a little more: some virtualization software doesn't limit resources per child, in which case even too much processing being done by one child could easily affect the others.
Even with hard limits on processing, excessive I/O done locally could also lag all the other children. However, since the boxes are rented/colocated, I wouldn't be surprised if there is also a SAN available to avoid the majority of the IO issues, but that is just speculation.
