Subject: unable to get guests network working ( VLAN 802.1q )
Date: Thu, 28 Feb 2013 10:30:58 +0100 [thread overview]
Message-ID: <512F23D2.7080905@esiee.fr> (raw)
Hello
I'm new to KVM ...
I've setup an hypervisor on a Debian server (7.0 RC1 )
and I have followed usual tutorial to do so.
Everything seems work well except I am unable to connect
the first guest I've build to my LAN.
I use 802.1q VLAN , the Cisco switch is configured to use it
and transport the VLANs on the connected port to the server
the 8021q module is loaded.
------------------------------------------------------------
interface GigabitEthernet1/0/6
description HYPVM
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2,30,110,150
switchport mode trunk
spanning-tree portfast trunk
------------------------------------------------------------
the /etc/network/interfaces of the server is pretty simple
------------------------------------------------------------
auto lo eth0 br-110 br-30
iface lo inet loopback
iface eth0 inet manual
iface br-30 inet static
bridge_ports eth0.30
bridge_maxwait 0
bridge_stp off
bridge_fd 0
address 147.215.1.25
netmask 255.255.255.0
broadcast 147.215.1.255
network 147.215.1.0
gateway 147.215.1.1
iface br-110 inet static
bridge_ports eth0.110
bridge_maxwait 0
bridge_stp off
bridge_fd 0
-------------------------------------------------------------
VLAN numbers are 30 and 110 , I can connect to the br-30 interface
from the LAN.
the guest host is supposed to have an IP address in the 147.215.110.0
network ( VLAN 110 ).
I can build it with virt-manager but when it try to access to the
LAN it fails ...
If someone could help ...
thanks in advance
