How to configure proxmox 4 network interface without physical access to KVM

I am running proxmox 4 with around 10 KVM and 14LXC.

I can configure ips and network from web GUI for LXC container.

I want to configure the Network interface For KVM without accessing the VM.

Is is possible to configure Network interface without accessing the VM.

As far as I know you can't configure the IP address in proxmox for a KVM vm (only for the lxc container you can define the ip address). For a KVM vm you can configure if the network connection is in Bridged mode or NAT.

For LXC containers you can use the pct command to set network for the container. More info about that on the Proxmox WIKI (scroll down to the Network section) - https://pve.proxmox.com/wiki/Linux_Container

What you could do for KVM would be to use a local DHCP server (you can install one on your proxmox if you want (apt-get install isc-dhcp-server). You have to define an ip address pool that will be assigned to your vms by the dhcp server.

Then configure the kvm machine using: qm command

qm set vmid options

From a man qm you discover this:

  -net[n] [model=]<enum> [,bridge=<bridge>] [,firewall=<1|0>] [,link_down=<1|0>] [,macaddr=<XX:XX:XX:XX:XX:XX>] [,queues=<integer>]
       [,rate=<number>] [,tag=<integer>] [,trunks=<vlanid[;vlanid...]>] [,<model>=<macaddr>]

So basically you can define the network for your kvm vm, say if it's bridged, set a specific mac address for that card.

If you want to add a specific ip to that vm you can do it based on its mac address (you have to configure in the dhcp server that a specific ip address is assigned to the desired mac address).
