Hi all.

After configuring bridge device, I got this /etc/network/interfaces file:

# cat /etc/network/interfaces
# network interface settings
auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

auto dummy0
iface dummy0 inet manual

auto vmbr0
iface vmbr0 inet static
address  172.21.43.99
netmask  255.255.255.128
 gateway  172.21.43.1
bridge_ports eth0
bridge_stp off
 bridge_fd 0

auto vmbr1
iface vmbr1 inet manual
bridge_ports eth1
 bridge_stp off
bridge_fd 0

auto vmbr10
iface vmbr10 inet manual
 bridge_ports dummy0
bridge_stp off
bridge_fd 9
 bridge_hello 2
bridge_maxage 12


But when I list the network devices with "ip" command, I get:
# ip a

DMESG also lists at it's end:

I would like someone to help me and point what I did wrong to enable these
"venet" and "tap10*" devices (device 8 up to 12).


Thanks for helping.
