Hi, I'm trying to run a guest domain in Xen 4.3.0. However, after I use xl create to create the guest domain dom1, it cannot connect to the network.
Inside dom1, when I ping www.google.com, it only shows: "PING www.google.com (74.125.228.19) 56(84) bytes of data.".
Inside dom0, I can use network. But I also saw in dom0 that the network manager *keeps trying to connect.* I did read the Network Configuration on Xen wiki and tried to use the bridge way and nat way, but either of them works. I think I must miss something and hope someone could help point out my error. I really want to get my domU's network work.
Here is my configuration files: [In Dom0]
