Package: ifupdown
Version: 0.7.5
Severity: normal
Dear Maintainer,
I am using Debian as the host OS in a KVM virtualization environment. In
testing Wheezy, I've discovered the following issue where an ethernet
alias is not brought up, and then a bridge alias is created rather than
a new bridge. Also, the bridge alias is set up for a vlan rather than
just the intended ethernet alias.
To illustrate, I have set up squeeze and wheezy the same way and included
output. Both machines installed with base+ssh server in tasksel with
thees packages installed afterward:
vlan bridge-utils qemu-kvm qemu-utils libvirt-bin
----
## interfaces file. except for IP, exact same on both machines.
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet manual
auto eth0.4094
iface eth0.4094 inet manual
vlan_raw_device eth0
auto br0
iface br0 inet static
address 10.205.16.8 # 8 == wheezy, 9 == squeeze
netmask 255.255.248.0
gateway 10.205.16.1
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
auto br0.4094
iface br0.4094 inet manual
bridge_ports eth0.4094
bridge_stp off
bridge_fd 0
bridge_maxwait 0
----
Squeeze: expected outcome; vms added to br0 and br0.4094 work as expected.

Wheezy: unexpected outcome; eth0.4094 isn't up, and also br0.4094
is not actually a bridge (see brctl output)
