brctl show :

bridge name         bridge id           STP enabled          interfaces

xenbr0                  8000.feffffffffff        no                         vif 9.0

it seems xenbr0 is started, any other suggestions?

thank you for quick answer !

 

I set "bridge=xenbr0" in domU, but I didn't check "brctl show"

 

I'll check it tomorrow ( the computer is not at hand right now :(  )

I'm no expert on bridged networking under Xen (I only use routed networking in production), but start by making sure "bridge=xenbr0" is in your domU vif config file (make sure you have a vif setup too....), and check the dom0 to make sure the bridge is bridging your domU to the physical NIC using "brctl show".

Hi, all,

I installed xen 3.0.3 on Ubuntu 7.10, and I set up VM dapper using xen-tools. Now, my VM can be boot successfully but without network.

I used wireshark and tcpdump to trace, I found that the vm sent requests to xenbr0, but xenbr0 didn't send them out !  In dom0, I can't see any request from domU.

In xend.conf, I use network-bridge and vif-bridge as default.

Maybe this problem is very simple, but as a beginner, it puzzled me a lot!

I do appreciate if someone can help me out. !

Best,
