[SOLVED] Vnet using same VLAN as Management Network

[MeCJay12]

Hello! I'm setting up the first node of a new HA cluster. As I'm configuring nodes, I'd like to configure as much at the Datacenter level as possible rather than making the same config on every node. This led me to SDN over local networking. The problem I'm having is that I want my nodes to have an IP and be accesssible over vlan 2 as well as some of my VMs and everytime I try to configure this, I either loose access to the node or the VMs. I was able to get this working using local networking by configuring bond0 with my physical interfaces then creating vmbr2 (not vlan-aware) assigned to bond0.2 and assigning my node IP to vmbr2. Both VMs and Proxmox were able to access vlan 2.

Now, I'm trying to move this config to SDN. I still have bond0 but now I have vmbr0 connected to bond0, a vlan zone connected to vmbr0, and a vnet with tag 2. I've tried every combination I can think of to get this working but nothing yet:

• vlan2 int connected to bond0.2
• vlan2 int connected to vmbr0.2
• vmbr2 (not vlan aware), tag 2 connected to bond0.2
• vmbr2 (not vlan aware), tag 2 connected to vmbr0.2

Any idea how to do this? Is it even possible or do I need to just keep that vlan as a local config. It seems like a trunk network already needs/is configured locally anyways.

in /etc/network/interfaces,

try:

iface <vnet>
address ....

where <vnet> is your vnet with tag2

it'll be merged with the generate sdn config.

Thank works! It even came up in the UI (even if I can't edit it in the UI) so it went better than I expected.
