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.

Even I execute "virsh nodeinfo" (by oneadmin) I have the same error lines:
-bash-3.2$ virsh nodeinfo

12:23:55.462: error : No vport operation path found for host0

This are inforamtion, I obatain from the fornt end:
