@Stephane, can you show your host network configuration and a VM's xml? Are you bridging the VM nics with the host's eth0 over your own br0, or are you using the default NATed virbr0? Does this happen even when only a single VM is up?
I will try to reproduce next week. (For host network configuration, the results of : sudo ifconfig -a sudo brctl show netstat -nr virsh net-dumpxml should suffice, and 'virsh dumpxml VM1' to show the xml configuration for a guest) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
