I have a dual port ConnectX-3 installed in a Dell R620 server running the following
- Centos 6.6
- mlnx driver 2.4.1.0.0.1
- Virtualbox 4.3.28
- Guest OS also Centos 6.6
- Bridged network adapter pointing to p1p1
Everything looks good when the VM boots up, I am able to ping remote machines over the 10G interface from the virtual machine and the host OS.
Problem occurs when I try to use the interface for anything more than ping, for example ssh to a machine on the 10G network.
This causes an error on the host OS, no error seen on the Guest OS.

Is there a configuration setting that needs to be set?
