 Posted: Wed Feb 22, 2017 5:10 pm Post subject: app-emulation/lxd starting an unprivileged systemd container |
 |
|
When i start
| Code: | | lxc launch images:centos/7/amd64 test1 |
or
| Code: | | lxc launch images:ubuntu/xenial/arm64 test2 |
the systemd init inside the container fails:
| Code: |
io linux # lxc exec test1 bash
[root@test1 ~]# ps aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.0 42480 3988 ? Ss 16:55 0:00 /sbin/init
root 12 0.0 0.0 11776 2880 ? Ss 17:11 0:00 bash
root 21 0.0 0.0 47448 3384 ? R+ 17:11 0:00 ps aux
[root@test1 ~]#
|
On an ubuntu system this works fine.
Can someone give me a hint where to look? |

Did you remember to compile your kernel with the appropriate support? See https://wiki.gentoo.org/wiki/LXD#Kernel_configuration
| Code: |
$ lxc launch lxc:centos/7/amd64 test1
Creating test1
Starting test1
14:15:51 atlas:~ 31%>lxc list
