[one-users] Hosts not monitored

[Alexandru - Florian Antonescu]

This problem is persisting even re-installation of OpenNebula 3.0.

I have tried to enable debugging by exporting ONE_MAD_DEBUG but I see no
extra messages logged to oned.log and no new file created in var folder.
Everything appears to be working properly, except that it doesn't.

These are the messages logged to var/oned.log
Fri Oct  7 09:18:53 2011 [InM][I]: Monitoring host zrhs9 (0)
Fri Oct  7 09:18:55 2011 [InM][I]: ExitCode: 0
Fri Oct  7 09:18:59 2011 [ReM][D]: HostPoolInfo method invoked

>From here it would seem that the monitoring code is executed properly.

Also, when I run onehost show 0 this is what is displayed:
HOST 0 INFORMATION
ID                    : 0
NAME                  : zrhs69
STATE                 : INIT
IM_MAD                : im_kvm
VM_MAD                : vmm_kvm
TM_MAD                : tm_shared

HOST SHARES
MAX MEM               : 0
USED MEM (REAL)       : 0
USED MEM (ALLOCATED)  : 0
MAX CPU               : 0
USED CPU (REAL)       : 0
USED CPU (ALLOCATED)  : 0
RUNNING VMS           : 0

MONITORING INFORMATION

The monitoring information is missing and no extra error message is
displayed.

Can someone give me some help with debugging this?

Best regards,
Florian
