Tried to make some reduced testcases:
The test is done on:
Linux kvm07 3.11.0-031100rc6-generic #201308181835 SMP Sun Aug 18 22:35:54 UTC
2013 x86_64 x86_64 x86_64 GNU/Linux
Later I tested it on Linux kvm07 3.11.0-031100-generic #201309021735 SMP Mon
Sep 2 21:36:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux, the problems was not
solved.
eth3 - testlan
driver: tg3
version: 3.132
firmware-version: 5719-v1.31 NCSI v1.1.15.0
bus-info: 0000:03:00.3
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
eth4 - vlan280
driver: be2net
version: 4.6.62.0u
firmware-version: 4.2.401.605
bus-info: 0000:24:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: no
Small kvm scripts:
sudo tunctl -u root -t tap42
sudo brctl addif vlan280 tap42
sudo ip link set tap42 up
sudo kvm -hda vdisk.img -cdrom /srv/ganeti/iso/linux-secure-13.04-64bit.iso -m
1024 -net nic -net tap,ifname=tap42,script=no -boot d
sudo tunctl -u root -t tap42
sudo brctl addif vlan280 tap42
sudo ip link set tap42 up
sudo kvm -hda vdisk.img -cdrom /srv/ganeti/iso/ubuntu-rescue-remix-11-10.iso -m
1024 -net nic -net tap,ifname=tap42,script=no -boot d
sudo tunctl -u root -t tap42
sudo brctl addif vlan280 tap42
sudo ip link set tap42 up
sudo kvm -hda vdisk.img -cdrom
/srv/ganeti/iso/clonezilla-live-2.1.1-7-amd64.iso -m 1024 -net nic -net
tap,ifname=tap42,script=no -boot d
Then I testet it on testlan (tg3 device), the testlan is on the same network at
vlan280
All the test working
sudo tunctl -u root -t tap43
sudo brctl addif testlan tap43xit
sudo ip link set tap43 up
sudo kvm -hda vdisk.img -cdrom /srv/ganeti/iso/linux-secure-13.04-64bit.iso -m
1024 -net nic -net tap,ifname=tap43,script=no -boot d
sudo tunctl -u root -t tap43
sudo brctl addif testlan tap43
sudo ip link set tap43 up
sudo kvm -hda vdisk.img -cdrom /srv/ganeti/iso/ubuntu-rescue-remix-11-10.iso -m
1024 -net nic -net tap,ifname=tap43,script=no -boot d
sudo tunctl -u root -t tap43
sudo brctl addif testlan tap43
sudo ip link set tap43 up
sudo kvm -hda vdisk.img -cdrom
/srv/ganeti/iso/clonezilla-live-2.1.1-7-amd64.iso -m 1024 -net nic -net
tap,ifname=tap43,script=no -boot d
Change the two network cards, that is testlan moved to eth4, vlan280
moved to eth3
Nothing worked at vlan280 and nothing worked at testlan. We could not
get at dhcp working on vlan280 (eth3 - tg3) driver.
The bridge setup is as followed, with or without the mac address setup, the
result is the same. And I remember to change it when change the bridge_ports.
The other 10Gbit interface is used to do drbd and is working without problems.
auto vlan280
iface vlan280 inet static

netmask 255.255.255.0

bridge_fd 0
bridge_stp off
