Vlan issue

[nourmail]

Hello,


I use a bonding of 3 NICs configured with LACP (802.3ad) ==> bond0
Then I created VLANs that points to the bond0.


All my VMs are connected to their VLAN without problems, except that when I restart the network interfaces with the command (/etc/init.d/networking restart), all my VMs lose connection and have to reboot the Proxmox node to restore it.

My configuration is :

# pveversion -v
proxmox-ve-2.6.32: 3.3-147 (running kernel: 2.6.32-37-pve)
pve-manager: 3.4-1 (running version: 3.4-1/3f2d890e)

Hi,
to make change on host bridge you should reboot (it's possible to do without reboot with promox 3.4 make your changes then restart network and stop and start all container ).
This because vm interface was add to host bridge by openVZ and not Debian.

So, it's normal.
Thank you very much.

You can also see output of "brctl show" before restarting network service and after. So after restarting networking you can manually add required interfaces to bridges by typing command "brctl addif <bridge> <interface>"
