剛剛更新完 PVE 重開機之後 container 就全都跑不起來了 錯誤訊息長這樣: ``` run_buffer: 571 Script exited with status 11 lxc_init: 845 Failed to run lxc.hook.pre-start for container "101" __lxc_start: 2034 Failed to initialize container "101" TASK ERROR: startup for container '101' failed ``` 仔細看一下 node 的 syslog 會寫 ``` Mar 17 03:30:55 router307 systemd-helper[1171]: dnsmasq: failed to create listening socket for 10.30.7.254: Address already in use Mar 17 03:30:55 router307 dnsmasq[1171]: failed to create listening socket for 10.30.7.254: Address already in use Mar 17 03:30:55 router307 dnsmasq[1171]: FAILED to start up Mar 17 03:30:55 router307 dnsmasq[1180]: started, version 2.90 cachesize 150 Mar 17 03:30:55 router307 systemd[1]: dnsmasq@nslab.service: Control process exited, code=exited, status=2/INVALIDARGUMENT Mar 17 03:30:55 router307 dnsmasq[1180]: DNS service limited to local subnets Mar 17 03:30:55 router307 systemd[1]: dnsmasq@nslab.service: Failed with result 'exit-code'.
