Hello


Not sure if this is the right list. You might get more help on the qemu-devel list.

I'm in trouble with a guest host that is not living on the same subnet
than the hypervisor that I would like to connect to my LAN through
802.1q VLAN ( ubuntu 12.10 server amd64 )

The hypervisor VLAN number is 30
The guest VLAN number is 110

See below the /etc/network/interfaces file of the hypervisor

# The loopback network interface
auto lo
iface lo inet loopback

# For  Guest-VM

auto em1.110
iface em1.110 inet manual

auto br0-110
iface br0-110 inet manual
bridge_ports em1.110
bridge_stp off
bridge_fd 0
bridge_maxwait 0

# For Vm-Mother

auto em1.30
iface em1.30 inet manual

auto br0-30
iface br0-30 inet static
address 147.215.1.25
netmask 255.255.255.0
network 147.215.1.0
broadcast 147.215.1.255
gateway 147.215.1.1
dns-nameservers 147.215.1.4 147.215.128.128
dns-search esiee.fr
bridge_ports em1.30
bridge_stp off
bridge_fd 0
bridge_maxwait 0


IF ANYONE COULD HELP ... Thanks a LOT


There isn't enough information here.. Which bridge do you connect your vm to?

Are you attempting to configure a vlan interface in the VM?

Does the swtich you are connected to know about vlan configuration?

What behavior do you see on the VM?

Thanks
