lxc-checkpoint失败并显示错误消息

Question

创建检查点失败，并且错误消息对我没有帮助。 我在做什么错了？

sudo lxc-create -t download -n bionic (`ubuntu`, `bionic`, `amd64`)
sudo lxc-start -n bionic -d

sudo lxc-checkpoint -n bionic -D /tmp/cp失败，并显示以下信息：

lxc-checkpoint: bionic: criu.c: do_dump: 1328 dump failed with 1
lxc-checkpoint: bionic: criu.c: do_dump: 1342 criu output: Will skip in-flight TCP connections

lxc-checkpoint: bionic: tools/lxc_checkpoint.c: checkpoint: 200 Checkpointing bionic failed

dump.log：

此问题是由于v1.6.1中iptables-restore缺少选项-w而引起的。 有关更多信息，请参见iptables issues for Ubuntu 18.04 #551和iptables-restore is missing -w option 。

一种选择是自己编译iptables-restore 1.6.2。
