The geust with the ID 12 has a vif device so its the guest with the name 10.10.10.221, does this guest can access the network or/and is reacheble from the network?

The guest system Âwith the name 10.10.10.221ïby xen-create-image makedï ïthe network is normnalã

I set configuration file 10.10.10.220.cfgïby copy from guest 10.10.10.221 ,through Previously create script ïï

vifÂÂÂÂÂÂÂÂ = [ 'ip=10.10.10.220 ,bridge=xenbr1 ,mac=00:16:3E:22:5K:2F' ]

but the vif still disabled ï

Vif13.0 interfaces belong to Guest ID : 10.10.10.220_10.04 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:

this vif interfaces that the line is disabled.

And the normal vif startup information is:

[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

Hello,

so it looks like that you still have the Xen network-scripts active in xend-config.sxp. Devices like pethX only get created by this scripts. When you setup a bridge manually you should disable this scripts. Only the vif-script vif-bridge have to be active so that the vif device of the DomUs can be connected to the bridge.

The geust with the ID 12 has a vif device so its the guest with the name 10.10.10.221, does this guest can access the network or/and is reacheble from the network?

Best Regards
