[pve-devel] [PATCH] Virtual vlan tagging to bridge interface

[Johannes Ernst]

Hello,

normally proxmox adds the vlan tag to the physical device (eth) like eth0.1 and creates then a bridge interface. If you using tunnel (gre, ipsec,..) or other interfaces vconfig cannot add a tagged interface. 

I changed the function to add interfaces to every device with an additional bridge. It creates a bridge (bridge1) to the interface and the tagged interface for it (bridge1.x). Then it creates another bridge and add this tagged bridge port to the new bridge (bridge2). Proxmox adds to this bridge the tap device of the vm.

You can trigger the solution over the datacenter.cfg. If you want to enable the virtual bridge solution add 'virtual_tagging: 1’ to the datacenter.cfg. Normally it use the default version.

For example:

1) normal solution

eth0 -> eth0.tag -> bridge1 -> vm

2) virtual tagged solution

eth0 -> bridge1 -> bridge1.tag -> bridge2 -> vm

Live print:

vmbr1		8000.666d7626577a	no		dummy0
							eth2

vmbr1v1		8000.666d7626577a	no		tap113i1
							vmbr1.1

It should be nice if everyone can test it too.

> A short description for that patch would be helpful.
