[systemd-devel] hostnamectl doesn't work in a lxc container

[Yuri Kanivetsky]

Hi,

Not sure it's a good place to ask. But it'd be great if you could help
me with this one. Or at least tell me where to ask. I failed to find
any systemd user mailing lists. The guys from lxc mailing list keep
silence:

https://lists.linuxcontainers.org/pipermail/lxc-users/2017-February/012840.html

So, on one physical server in a lxc container I get this:

# hostnamectl --static
Could not get property: Connection timed out
# hostnamectl
# echo $?
1

Occasionally I get this error message:

Could not get property: Failed to activate service
'org.freedesktop.hostname1': timed out

And in the log I see this:

Feb 10 12:39:04 server1 dbus[79]: [system] Activating via systemd:
service name='org.freedesktop.hostname1'
unit='dbus-org.freedesktop.hostname1.service'

Feb 10 12:39:29 server1 dbus[79]: [system] Failed to activate
service 'org.freedesktop.hostname1': timed out

On the other server it works though. Here's what I see in the log:

Feb 10 14:40:26 server2 dbus[25957]: [system] Activating via
systemd: service name='org.freedesktop.hostname1'
unit='dbus-org.freedesktop.hostname1.service'

make it unresolveable. Please install nss-myhostname!

activated service 'org.freedesktop.hostname1'
Feb 10 14:40:26 server2 systemd[1]: Started Hostname Service.

What's causing it? What can I check? How do I remedy this? Thanks in advance.

Yuri
