[one-users] Xen poll on Debian 6

[Ara Sadoyan]

Hello, 

I have installed  opennebula-2.2.1  on Debian 6. Oned is running under
user one. 
I have 1 Oneadmin host and 2 Xen Hypervisors. Both hosts are with exact
same hardware and software configuration. 
When I execute  /tmp/one/vmm/xen/poll one-6 on host 1 I get correct
state "STATE=a NETTX=395 USEDCPU=0.0 USEDMEMORY=1041664 NAME=one-6
NETRX=0" 
but on  second host i get this 

/tmp/one/vmm/xen/poll one-9
Error executing sudo /usr/sbin/xentop -bi2
/tmp/one/vmm/xen/poll:186:in `get_vm_info': undefined method `[]' for
nil:NilClass (NoMethodError)
from /tmp/one/vmm/xen/poll:310:in `print_one_vm_info'
from /tmp/one/vmm/xen/poll:344

sudo /usr/sbin/xentop -bi2 on both hosts shows correct output

240    0

Sudo is configure properly  and same in both hosts 
%one    ALL=(ALL) NOPASSWD: /usr/sbin/xm *
%one    ALL=(ALL) NOPASSWD: /usr/sbin/xentop *

In host 1 after running some time I got this. 
/tmp/one/vmm/xen/poll one-3
STATE=d
/tmp/one/vmm/xen/poll one-4
STATE=a NETTX=717 USEDCPU=0.0 USEDMEMORY=1041664 NAME=one-4 NETRX=0
/tmp/one/vmm/xen/poll one-6
STATE=a NETTX=429 USEDCPU=0.0 USEDMEMORY=1041664 NAME=one-6 NETRX=0

virsh is also configured normally and shows VMs with virsh list command
with user one. 

Have anyone get this problem and solved it ?

Thanks 
Ara
