[Bug 997978] Re: KVM images lose connectivity with bridged network
This bug is considered fixed for me. Not a single network glitch since installing the package from PPA.

Installed yesterday and rebooted the dom0 machine and thus all virtual machines.

It took a few days, but we've finally had a failure of VM instance 2. It died 2.5 hours ago. Logging into the dom0 host shows the arp table dead for that host: mailer02..com (incomplete) br0 Logging into the machine itself via console: root:~# ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:d3:8f:91 inet addr:212.XX.239.101 Bcast:212.XX.239.111 Mask:255.255.255.240 inet6 addr: fe80::5054:ff:fed3:8f91/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6893246 errors:0 dropped:0 overruns:0 frame:0 TX packets:8242152 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2290922658 (2.2 GB) TX bytes:3314395798 (3.3 GB) root:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric RefUse Iface 0.0.0.0 212.XX.239.97 0.0.0.0 UG10000 eth0 212.XX.239.96 0.0.0.0 255.255.255.240 U 0 00 eth0 Restarting the network on the vm (/etc/init.d/networking restart) does nothing. Rebooting the VM brings it back to life. I'm happy to try with the container again, but using the instructions provided (even with some additional research online), I can't get it running.

[Bug 997978] Re: KVM images lose connectivity with bridged network
Hey, There is no DHCP server for that network, which is why I set up the static IPs. The cgroup-bin package wasn't installed, I installed that and then grep showed some output: root:~# grep cgroup /proc/self/mounts cgroups /sys/fs/cgroup tmpfs rw,relatime,mode=755 0 0 cgroup /sys/fs/cgroup/cpu cgroup rw,relatime,cpu 0 0 cgroup /sys/fs/cgroup/cpuacct cgroup rw,relatime,cpuacct 0 0 cgroup /sys/fs/cgroup/devices cgroup rw,relatime,devices 0 0 cgroup /sys/fs/cgroup/memory cgroup rw,relatime,memory 0 0 cgroup /sys/fs/cgroup/freezer cgroup rw,relatime,freezer 0 0 The container has now started. I'll configure it so it's running the same software as the other VMs and let's see what happens over the coming days.

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.
