Static IP Address for Bridged OpenVZ VMs?

[wnpaul]

I have been wondering about the fact that when one selects "Bridged" for the network of a new OpenVZ virtual machine, there is no option to specify an IP address in the GUI screen.

Is the assumption that all virtual machines will get their IP information via DHCP?

If so, it would be nice if the GUI creation success message showed the MAC address of the network interface, so one can go and create a static IP address on the DHCP server before powering the machine up.

Of course it would also be nice if there were a way to provide a static address for the new VM through the GUI, instead of having to use the commandline vzctl command.

if you choose bridge you need to configure the network inside the VM - like you configure it on a KVM guest or a physical host.

Really? So far, after creating an OpenVZ VM with bridged network I have simply gone to a ssh session on the PVE server and typed,

vzctl set VMID --ipadd 192.168.0.xxx --save

before starting the VM, and this seems to work just fine.

It seems that if the GUI provided an input field for the IP address, the web app could then execute that same command on the PVE server ...

Anyway, not complaining just suggesting

That way you mix veth with venet. Above command just configures venet (it does not configure the bridged ethernet device).

Ah, understood. Thanks!
