Today I can finally reproduce the problem. This is most certainly an Ubuntu package update problem + need to understand how to fix it. Currently only fix is reboot.\r\n\r\n1) Working Ubuntu + LXD running several containers.\r\n\r\n2) Do a simple package update. Exact update from this morning...\r\n\r\n/usr/bin/aptitude upgrade\r\nThe following packages will be upgraded: \r\n  lxd lxd-client lxd-tools php7.0-cli php7.0-common php7.0-json php7.0-opcache php7.0-readline python3-distupgrade ubuntu-release-upgrader-core\r\n\r\nAll packages update successfully.\r\n\r\n3) At this point systemctl shows both services lxd + lxd-containers both stopped + restarted successfully.\r\n\r\n4) lxc info --show-log $container - shows all containers are functional.\r\n\r\n5) Problem: private IPs 10.0.119.xxx are pingable + public IPs are all dead.\r\n\r\nInside container both 10.0.119.xxx are pingable + public IPs are pingable.\r\n\r\nOutside container (on host) public IPs are all dead (100% packet loss).\r\n\r\nThis occurred on one machine this morning + I went through the exact same upgrade process on a 2nd machine + all public IPs died on 2nd machine too.\r\n\r\nMy guess is an LXD networking guru will know exactly how to fix this + maybe how to reconfigure Ubuntu (systemd maybe?) so LXD containers survive simple updates.\r\n\r\nThanks.\r\n________\r\nSetup details.\r\n\r\nnet12 # lxd --version \r\n2.6.2\r\n\r\nnet12 # lsb_release -sc\r\nyakkety\r\n\r\n```\r\nnet12 # lxc list\r\n+--------------------------+---------+--------------------------------+-----------------------------------------------+------------+-----------+\r\n|           NAME           |  STATE  |              IPV4              |                     IPV6                      |    TYPE    | SNAPSHOTS |\r\n+--------------------------+---------+--------------------------------+-----------------------------------------------+------------+-----------+\r\n| ja1-discover-free-ebooks | RUNNING | 10.0.119.202 (eth0)            | fd42:9a2b:d62f:7e98:216:3eff:fe5f:db43 (eth0) | PERSISTENT | 0         |\r\n|                          |         | 144.217.33.225 (eth0)          |                                               |            |           |\r\n+--------------------------+---------+--------------------------------+-----------------------------------------------+------------+-----------+\r\n| yakkety                  | RUNNING | 10.0.119.85 (eth0)             | fd42:9a2b:d62f:7e98:216:3eff:fe36:18 (eth0)   | PERSISTENT | 0         |\r\n|                          |         | 144.217.33.224 (eth0)          |                                               |            |           |\r\n+--------------------------+---------+--------------------------------+-----------------------------------------------+------------+-----------+\r\n```\r\n\r\nMachine setup per https://github.com/lxc/lxd/issues/2534 previous discussion."}}
