[one-users] Host hook failure

[Carlos Jiménez]

Hi all,

I have one computer running OpenNebula and two hosts with KVM.
I have configured "HOST_HOOK" and "VM_HOOK" on /etc/one/oned.conf:
/
//HOST_MONITORING_INTERVAL         = 600//
//VM_POLLING_INTERVAL            = 600//
//HOST_HOOK = [//
//    name      = "error",//
//    on        = "ERROR",//
//    command   = "ft/host_error.rb",//
//    arguments = "$ID -r",//
//    remote    = "no" ]//
//VM_HOOK = [//
//   name      = "on_failure_resubmit",//
//   on        = "FAILED",//
//   command   = "/usr/bin/env onevm resubmit",//
//   arguments = "$ID" ]/

I've powered off one of the hosts, with one VM running. The VM polling 
and Host monitoring intervals are set to default. After 10-15 minutes, 
the host is detected as failed (ERROR state) but the VM is not 
resubmitted yet. According to the logs, it seems to be a problem in the 
execution of the "recovery" script.
The failed host ID is 5 and the affected VM ID is 36.

This is the relevant part of the log:
/

Could you give advice on how to solve this issue?
Let me know if you need more information.


Thanks in advance.
