On a KVM host, after gracefully shutting down the guest KVM, I get:

[root@kvm]# /sbin/shutdown -h now

Broadcast message from
        (/dev/pts/1) at 15:23 ...

The system is going down for halt NOW!
**shutdown: Method "EmitEvent" with signature "sasb" on interface "com.ubuntu.Upstart0_6" doesn't exist**

And I cannot reboot the machine. The same happens for -Ph or -r.


UPDATE 1: I will place this question on hold until the next time I have to restart this machine.

UPDATE 2: reboot works.

How about poweroff and reboot ? – ewwhite Jan 6 '14 at 20:46

.. did you tried halt? one of the first I'd do is head over to /etc/sysconfig/network-scripts/ifcfg- to see how my interfaces are configured, you're saying it's CentOS, yet I'm also seeing ubuntu there, so double check, I think your problem is somewhere there...

The Ubuntu reference is because EL6 uses Upstart. – ewwhite Jan 6 '14 at 21:19
@ewwhite I'm using CentOS on one of my boxes, and I'm not seeing any ubuntu references in there, probably because I'm not using upstart, thanks for pointing this out for me. – alexus Jan 6 '14 at 21:23
do a find&grep for "com.ubuntu.Upstart0_6". it's in there a few times. CentOS 6.5 – Gaia Jan 6 '14 at 21:57
didn't try halt, poweroff or reboot. it's always been shutdown on this server. – Gaia Jan 6 '14 at 21:58
@Gaia Please try them. – ewwhite Jan 7 '14 at 3:08
