The vif12.0 is guest id 10.10.10.221ã

 

Dmesg info

Vif13.0 interfaces belong to ÂGuest ID : 10.10.10.220_10.04Â but disabled.

Normnal state is entering forwarding state .

 

Why ?

Whether through a copy guest system ,must be set some configuration file?

 

 

The same, I'm running on ubuntu 8.04 xen dom0, but no such the problem.

Hiï

 

in the ubuntu 12.04 ,i installed the xen dom0 success.

In the startup xen guest, the guest system can be the normal starting, but guest system vif interface does not exist.

View dmesg log shows:

[2062.382385] device vif9.0 entered promiscuous mode

[2062.387698] ADDRCONF (NETDEV_UP) : vif9.0: link is not ready

[2076.856078] eth1: port 4 (vif9.0) entering disabled state

[2076.856268] eth1: port 4 (vif9.0) entering disabled state

 

this  vif interfaces that the line is disabled.

 

And the normal vif startup information  is:

[2035.861524] ADDRCONF (NETDEV_UP) : vif7.0: link is not ready

[2048.585999] xen-blkback: ring-ref 8, event-channel 9, protocol 1 (x86_64-abi)

[2048.648746] ADDRCONF (NETDEV_CHANGE) : vif7.0: link becomes ready

[2048.648801] eth1: port 2 (vif7.0) entering forwarding state

[2048.648806] eth1: port 2 (vif7.0) entering forwarding state

 

why the vif interfaces disabled?

 

what's wrong ?

how can I do ?

Hello,

it would be useful to know if you run a HVM or PV guest and how your configuration look like. I don't have issues with Xen on Ubuntu 12.04 and Debian. The only case where I had problems was when the vif option in the configuration file of a HVM has the option type=ioemu. There it happened that the vif interface couldn't be setup correct or stopped after a while.

Best Regards

Hello,

xen-create-image should generate a DomU configuration file in the specified output dir. Could you show us the configuration file of the DomU and the configuration of you bridge in /etc/network/interfaces. If you have created the bridge with the script network-bridge try to create the manually and try to start the guest with this bridge. So a possible bridge configuration could look like this:

auto xenbr0
iface xenbr0 inet static
    address IP-ADDRESS of Dom0
    netmask NETMASK-FOR-THE-NETWORK
    gateway GATEWAY-OF-THE-NETWORK
    bridge_ports eth0
    bridge_stp off (Spanning tree protocol is disabled in this case)
    bridge_fd 0 (sets the default forward delay)

The configuration for eth0 then must look like this:

auto eth0
iface eth0 inet manual

The configuration line for vif in the DomU configuration should look like this:

vif    [ 'bridge=xenbr0,ip=IP-OF-DOMU,mac=WANTED-MAC-ADDRESS' ]

Best Regards
