[one-users] [Monitor Error] Error executing xen.rb. Please help!!!!

[張德勤]

Dear all：

I am new in OpenNEbula.

I have two machines, one is server, and the other one is client1.
1. server ：CentOS 6 + Opennebula 3.0.0
2. client1：CentOS 6 + XEN-kernel(2.6.32.56-1.el6xen.x86_64) +XEN

I have a problem about running onehost list but something wrong.

[oneadmin at server ~]$ onehost list
  ID NAME               RVM   TCPU   FCPU   ACPU   TMEM   FMEM   AMEM   STAT
   4 client1              0      0      0    100     0K     0K     0K    err

[oneadmin at server ~]$ onehost show 4

MONITORING INFORMATION
ERROR=[
  MESSAGE="Error monitoring host 4 : MONITOR FAILURE 4 Error executing

  TIMESTAMP="Wed Mar  7 03:14:59 2012" ]


one part of my oned.log is following....

Wed Mar  7 03:24:55 2012 [ReM][D]: VirtualMachinePoolInfo method invoked

Wed Mar  7 03:24:55 2012 [InM][E]: Error monitoring host 4 : MONITOR
FAILURE 4 Error executing xen.rb


And, I tried run the command on client1, it can monitor my client1 self.....
But, I must input my password...
Is this reason that my ONE server can't monitor the client1???

[oneadmin at client1 xen.d]$ pwd
/var/tmp/one/im/xen.d
[oneadmin at client1 xen.d]$ ./xen.rb
[sudo] password for oneadmin:
HYPERVISOR=xen
TOTALCPU=400

Someone can help me???
