Hi Carlos,
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.
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.
[oneadmin at dn07 ~]$ /var/tmp/one/vmm/xen/poll one-28
Error executing sudo /usr/sbin/xentop -bi2
/var/tmp/one/vmm/xen/poll:186:in `get_vm_info': undefined method `[]'
for nil:NilClass (NoMethodError)
from /var/tmp/one/vmm/xen/poll:314:in `print_one_vm_info'
from /var/tmp/one/vmm/xen/poll:348
Can you think of any other thing that I could test?
Thank you very much in advance.
BR,
María
