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)
Regards,
Uwe
