1. 如果要使用 mount 光驱，不做下面的操作的话，会报错
[root@DM-31 ~]# mount -o loop dm8_setup_rh7_64_ent_8.1.1.45_20191121.iso /mnt/iso
mount: /root/dm8_setup_rh7_64_ent_8.1.1.45_20191121.iso: failed to setup loop device: No such file or directory
或
[root@ConterOs7-DM-31 ~]# mount -o loop dm8_setup_rh7_64_ent_8.1.1.45_20191121.iso /mnt/iso
mount: /root/dm8_setup_rh7_64_ent_8.1.1.45_20191121.iso: failed to setup loop device: Permission denied
- 新建CT的时候，
“无特权的容器”一定要选否
- 新建后，编辑
/etc/pve/nodes/znkdell720xd/lxc/120.conf文件，添加以下内容（不同的ct都要修改对应的ID文件）
lxc.cgroup.devices.allow = b 7:* rwm lxc.cgroup.devices.allow = c 10:237 rwm lxc.mount.entry = /dev/loop0 dev/loop0 none bind,create=file 0 0 lxc.mount.entry = /dev/loop1 dev/loop1 none bind,create=file 0 0 lxc.mount.entry = /dev/loop2 dev/loop2 none bind,create=file 0 0 lxc.mount.entry = /dev/loop3 dev/loop3 none bind,create=file 0 0 lxc.mount.entry = /dev/loop4 dev/loop4 none bind,create=file 0 0 lxc.mount.entry = /dev/loop5 dev/loop5 none bind,create=file 0 0 lxc.mount.entry = /dev/loop6 dev/loop6 none bind,create=file 0 0 lxc.mount.entry = /dev/loop-control dev/loop-control none bind,create=file 0 0

2. 如果要使用 docker 启用容器，不做下面的操作的话，会报错
docker: Error response from daemon: oci runtime error: container_linux.go:265: starting container process caused "process_linux.go:368: container init caused \"rootfs_linux.go:57: mounting \\\"proc\\\" to rootfs \\\"/var/lib/docker/vfs/dir/20a621a73755db3f4030bc67bbf7ff9540bd1d63bb348d8be440d8ca63d3c922\\\" at \\\"/proc\\\" caused \\\"permission denied\\\"\"".- 修改CT的 “选项”-“签名”-“嵌套”
