[PVE-User] Cluster nodes in different subnets/VLANs

[Emmanuel LESTRELIN]

You are right, and that is the case : subnet 192.168.100.0/24 stands in VLAN 100, and subnet 192.168.200.0/24 in VLAN 200.
Historically, I had two Proxmox VE hosts on those two distinct subnets. I decided to put both in one cluster in order to be able to perform live migration beetween my two hosts.

On the host standing in VLAN 100, I have created vmbr1 bound to eth0.200 and I have configured the corresponding switch port in trunk mode with default (untagged) VLAN to 100.

Then I have migrated all the VEs on the host standing in VLAN 200 to the host in VLAN 100, and reconfigured them to bind to vmbr1.

Finally, on the host on VLAN 200, I have bound vmbr0 to eth0.100, vmbr1 to eth0 with the original ip and gateway addresses, and configured the switch port in trunk mode with default (untagged) VLAN to 200.

So I have the configuration you described : 

  * vmbr0 : VLAN 100 on both nodes
  * vmbr1 : VLAN 200 on both nodes

So what network config do you use now? (/etc/network/interfaces)
