[Xen-users] No network connection on domains

[Mortarien <mortarien@xxxxxxxxx>]

Hello,

 

I'm having a problem with network connection on created domains. I'm running Xen 3.2 on Ubuntu 8.04, server has 2 NICs but I use only one. I had no problems installing and running Xen, domU has normal network connection, but none of other domains.

 

My current test domain is set for dhcp, but it doesn't pick up any signal. Same situation was with fixed network settings, domain behaved as though it was "unplugged". Checked all settings on guest system, they seem to be more than fine. On host system, I am anxious about double eth0 in network-bridge status (see below), but I have no idea where it came from and how to get rid of it. I also failed to find anyone with similar problem.

 

 

Cheers,

Kamila Gador
