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 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
