Hello i created some months ago a bridge between my private interface eth2 and proxmox (4.3)

vmbr1 Link encap:Ethernet HWaddr 18:a9:05:5e:0c:54
inet addr:10.10.30.4 Bcast:10.10.255.255 Mask:255.255.0.0
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)


auto vmbr1
iface vmbr1 inet static
address 10.10.30.4
netmask 255.255.0.0
bridge_ports eth2
bridge_stp off
bridge_fd 0

Unfortunately the private network do not working anymore because the eth2 interface is inactive, i checked into the gui and i saw that is set yes to autostart and no to active......

So i tried to start the eth2 manually from ssh but im getting the following error:

root@prox:~# ifup eth2
RTNETLINK answers: File exists
Failed to bring up eth2.

I tryied also to run
root@prox:/etc/network# ifconfig eth2 up
SIOCSIFFLAGS: Device or resource busy


While this server have several productions VM is it possible to restart in a different way the eth2 without reboot the server ?

Thanks
