I wouldn't really consider myself a "typical user", but I believe that
this was disk I/O (or lack thereof) that was causing the issue, not a
network issue.  I ran packet tests with Silicon Dust's instructions,
and even during this I attempted to saturate the NIC on the VM host by
transferring a large amount of data with other VMs (on the same host)
and I never lost a single packet.
