Ok, looking back over the original description, the bug poster has an eth0 mac address of d4:ae:52:84:2d:5a. I'm quite certain that is at least a part of the problem - the bridge will always take the lowest mac address of any device on it, and the nics on the VMs have lower mac addresses. So any time a VM goes on or offline, the bridge mac address will change, causing network traffic to pause.
Georg, please show 'ifconfig -a' output while the VMs are running -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bridge-utils in Ubuntu. https://bugs.launchpad.net/bugs/997978 Title: KVM images lose connectivity with bridged network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/997978/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
