Hi Tino,
I changed as you advised and it prints:
<VM_POOL/>

Hi,
Everything seems alright, except for the xpath expression returned
nil
object. So please let's try debugging the vms fetched:
---
class OpenNebula::VirtualMachinePool
attr_reader :xml
end
my_file.puts vms.xml

Regards,

Hi,
Please try the following:

Also, please send the output of

Hi Zaina,
Could you please print out also the content of "vm_ids_array"? I
am
afraid the xpath expression may not be doing its job.

Hi,
I checked the ruby script that's called and it seems that the
array
containing the list of VMs is empty
vm_ids_array =
vms.retrieve_elements("/VM_POOL/VM[STATE=3]/HISTORY[HOSTNAME=\"#{host_name}\"]/../ID")
I tried printing something to a tmp file to make sure that the
script
gets
the right host id.
my_file = File.new("/tmp/remove_me.txt", "w")
my_file.puts "OpenNebula host has failed #{ARGV[0]}"
The hostname and host_id are correctly detected by the script.
Thank you for any hints on how to fix this,

Hi,
I'm having some trouble getting the HOST_HOOKS to work:
I added this to the configuration file and restarted oned.
HOST_HOOK = [
name = "disable",
on = "DISABLE",
command = "host_error.rb",
arguments = "$HID -r y",
remote = "no" ]
However when I disable a host using "onehost disable" the VMs
aren't
re-submitted.
The oned.log doesn't indicate that the hook has been
triggered.
I'm using OpenNebula 2.2 and the script host_error.rb is
indeed
located in my $ONE_LOCATION/share/hooks/
What am I doing wrong? Thanks
