  1. Can you restart the network service? (on the openvz host.. etc..)

    Yes

    What will happen?

    Best case scenario: Nothing (horribly detrimental that is)

    Worst Case: Loss of networking on the host. Loss of any connectivity to the host. Loss of any connectivity to the VMs. Critical Application failures on the VMs due to network connectivity issues. Corruption of databases etc.

    The server could also explode killing everyone in the datacenter... (But there is just always a risk that the server was armed with a high yield nuclear device and the trigger was the service network restart command... Those are just risks most of us are willing to accept).

    We can't tell you what will happen.

    We don't know your VMs or their applications or even your network configuration. We don't recommend you do this unless you have a very VERY good concrete reason to do so... and even then we would urge you to find a way to do what you need without interrupting the network connectivity.
