This happens to one of the VMs at any one time (on Wednesday two failed, about 2 hours apart). There's no discernible pattern in terms of time of day or length of a VMs uptime.
The next time one fails (they've been stable today), I'll do a route -n and post the output. For record, currently (with a working VM), route -n shows: $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 212.XX.239.97 0.0.0.0 UG 100 0 0 eth0 212.XX.239.96 0.0.0.0 255.255.255.240 U 0 0 0 eth0 -- 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
