order kvm network devices

[pva00]

Great things your doing with proxmox.

I'm using a KVM which need uses multiple nics through vmbr0 - vmbr3. In the kvm eth0 must be connected through vmbr1 and vmbr0 must be connected through eth1. Within proxmox I cannot change the order of the vmbrX at the hardware tab ethernet devices of my kvm node. Is it possible to have ths feature in the next release

Thanks....

I am confused - please can you describe more elaborate what you want to do?

Example:
In my proxmox server I have 4 nics for network a,b,c&d connected to eth0, eth1, eth2, eth3. Proxmox connects vmbr0, vmbr1, vmbr2, vmbr3. So I have:

a --> eth0 --> vmbr0
b --> eth1 --> vmbr1
c --> eth2 --> vmbr2
d --> eth3 --> vmbr3

Now I have a firewall appliance with 4 virtual nics eth0, eth1, eth2, eth3. I can't change the first connention eth0 (IPCOP green interface). Connection must be as follewed:

a --> eth0 --> vmbr0 --> eth2
b --> eth1 --> vmbr1 --> eth1
c --> eth2 --> vmbr2 --> eth0
d --> eth3 --> vmbr3 --> eth3

But this is not possible I always get:
a --> eth0 --> vmbr0 --> eth0
b --> eth1 --> vmbr1 --> eth1
c --> eth2 --> vmbr2 --> eth2
d --> eth3 --> vmbr3 --> eth3

So wrong interface connected to the wrong network. I can't change the appliance. So in the futere the order of the virtual nics should be possible in proxmox or I have to do:
c --> eth0 --> vmbr0 --> eth0
b --> eth1 --> vmbr1 --> eth1
a --> eth2 --> vmbr2 --> eth2
d --> eth3 --> vmbr3 --> eth3

And change some other KVM virtual machines their nics....

It is a request for the future no bug....

not sure if I understand what you are doing but on the Proxmox VE you can assign interface to bridges.

e.g. you can assign vmbr0 eth0, eth1, eth2 or eth4

I still don't get it. If you appliance can't order the interfaces you have a problem there.

Anyways, you can always plug the cable to other port, or simply change the vbmrX -> ethY asssignment, or change the device names in /etc/udev/rules.d/70-persistent-net.rules.

We're running IP-Cop happly since about 4-5 years. One problem we recogniced all time was the assignment of the network cards via setup in IPcop.
If you're using instances of the same NetworkICard you finally can't assign them to red/green/etc.) .
It's the same via PVE which we're using for the job since a few months.
We simply re-assigned the interfaces by hand via ipcop's network config file (SSH Login using nano editor).
