[mvapich-discuss] osu benchmark over 10GE - hydra_pmi_proxy issue

[Hoot Thompson]

The two VMs are talking fine. There are actually three network connections
between the two VMs.

192.168.122.x ­ regular Gigabit interface that interconnects the two VMs
with the bare metal hosts. VMs can talk to hosts and to each other
10.10.10.x ­ 10GE connection that exists only between the VMs
10.10.20.x -= 10GE that exists only between the VMs
