Hi Carlos,<br>
<br>
I have checked the directory /var/tmp/one/vmm/xen in the nodes and
/$ONE_LOCATION/var/remotes/vmm/xen in the front-end, the content of
both is the same. This means that the update has been made correctly
in the nodes.<br>
<br>
I have looked in log file the error before the update and it is
different. The messages are the following, in case they can help.<br>
<br>
<b>BEFORE</b><br>
Error executing sudo /usr/sbin/xentop -bi2<br>
/var/tmp/one/vmm/xen/poll:186:in `[]': can't convert String into
Integer (TypeError)<br>

from /var/tmp/one/vmm/xen/poll:314:in `print_one_vm_info'<br>
from /var/tmp/one/vmm/xen/poll:348<br>
ExitCode: 1<br>

<b>AFTER</b><br>

from /var/tmp/one/vmm/xen/poll:348<br>

<br>
<br>
You can say to me if I can test some to help in this.<br>
Thank you very much in advance.<br>
Regards,<br>
María<br>

Maybe the problem is that OpenNebula copies updated files when the
monitorization takes place.<br>
Could you please check that /var/tmp/one/vmm/xen/poll in your
remote host has the updated code?<br>
<br>
Anyway, we are going to test this issue in our local
infrastructure, hopefully we'll come up with a fix soon.<br>
<br>

Hi Carlos,<br>
<br>
Before anything else, sorry for the delay in my answer.I
have been very busy this past month and I haven't been able
to test the patch that you prepared to solve the monitoring
problem. <br>
<br>
Finally last week I tested the patch but the monitoring
problems continue although the machines no longer happen to
unknown state. I have executed from line of commands but the
messages are the same that they appear registered in logs.<br>
<br>
[oneadmin@dn07 ~]$ /var/tmp/one/vmm/xen/poll one-28
<div class="im"><br>
Error executing sudo /usr/sbin/xentop -bi2<br>
</div>
/var/tmp/one/vmm/xen/poll:186:in `get_vm_info': undefined

`print_one_vm_info'<br>
from /var/tmp/one/vmm/xen/poll:348<br>
<br>
<br>
Can you think of any other thing that I could test?<br>
<br>
Thank you very much in advance.<br>

This error causes that the VM is not monitored
correctly, also the machines happen to unknown
state. Do you think that this error will have
something to do with the unknown state of the
VM?<br>
<br>
<br>
Thank you very much.<br>

Hi again,<br>
<br>
I have another problem with the

The log file contains the following

Any idea? Thank you very much by
