Lab 3.2 - lxc-start -n unpriv-cont-user

axa0176

When we are trying to spin up a container using LXC, it it says to:

1. There was no setfacl so I did 'sudo apt install acl'
2. Use setfacl on .local (setfacl -R -m u:231072:x ~/.local). There was no .locaI directory so I created it (touch ~/.local).

student@ubuntu:~$

I follow the instructions and the container installs fine but won't start:

student@ubuntu:~$ lxc-start -n unpriv-cont-user -d
lxc-start: unpriv-cont-user: lxccontainer.c: wait_on_daemonized_start: 877 Received container state "ABORTING" instead of "RUNNING"
lxc-start: unpriv-cont-user: tools/lxc_start.c: main: 306 The container failed to start
lxc-start: unpriv-cont-user: tools/lxc_start.c: main: 309 To get more details, run the container in foreground mode
lxc-start: unpriv-cont-user: tools/lxc_start.c: main: 311 Additional information can be obtained by setting the --logfile and --logpriority options

Could this be because the .local file directory didn't exist? I created my VM using VM Workstation but everything appears to be smooth.

Hi @axa0176,

.local is expected to be a directory, not a file.
The touch command creates a file.
The mkdir command creates a directory.

Hi Chris,

Thanks for the response. I realized the .local directory wasn't being created because I made a typo when I was adding the student to a configuration file. Once I fixed that typo the .local directory was automatiically created:

student@ubuntu:~$ sudo bash -c 'echo student veth lxcbr0 10 >>
/etc/lxc/lxc-usernet'

I was typing lxbr0
