[PVE-User] looking for recommendations of VLAN setup

Hi all,

I would like to hear recommendations regarding the network setup of a Proxmox cluster. The situation is the following:

* Proxmox hosts have several ethernet links
* multiple VLANs are used in our datacenter
* I cannot guarantee that the VLANs are on the same interface for each host (meaning VLAN 1234 could be on eth1 for host A but on
eth3 for host B, e.g. due to performance reasons)
* passing through a VLAN trunk to a VM currently doesn't seem to be necessary

My thought was that I would need to create a VLAN interface for each used VLAN (say ethX.1234) and on top of that configure a
Linux bridge (vmbr1234). This should abstract away the physical network situation from the VMs.

What kind of network setup would you recommend?

One additional question: does Proxmox stop me from migration a VM to a host that doesn't provide VLANs necessary to that
particular VM? (e.g. a VM needs VLAN 1234 but some of the hosts aren't connected to this VLAN)
