Hi all,

I configured OpenNebula front end in my pc "solaris" (Ubuntu 9.04)and installed two cluster nodes "ivanov" (Ubuntu 9.04) and "omii001" (Scientific Linux CERN SLC release 5.4 : 2.6.18-164.2.1.el5
x86_64).
My problem is that, on the second node (omii001), total memory,CPU time and free CPU are not updated when am issuing the onehost list command.

oneadmin at solaris:~$ onehost list
 HID NAME                      RVM   TCPU   FCPU   ACPU    TMEM    FMEM STAT
   2 ivanov                      0    200    193    193 2060728 1651592   on
   4 omii001                     0      0      0    100       0 3972204   on

If I execute on omii001
/tmp/one-im/one_im-218131afa926b52434fc7ee9e027cddf I have different behaviour, If I am root or oneadmin user.
To be more precise, the error lines don't appear if I run the command in succession, I mean, without waiting more then some minutes.

[root at omii001 var]#  /tmp/one-im/one_im-218131afa926b52434fc7ee9e027cddf

Even I execute "virsh nodeinfo" (by oneadmin) I have the same error lines:

-bash-3.2$ virsh nodeinfo
