Description

Hi,
Sorry for the cut and paste from IRC #opennebula

[15:12] <jpi_> i can not get the "requirement" statement in VM template to work
[15:12] <jpi_> I have defined a custom script to monitor the load of the hosts in my cluster
[15:13] <jpi_> and want to schedule VMs on a "not so loaded" node
[15:13] <jpi_> my syntax is : REQUIREMENTS = "LOAD15 < 1";
[15:14] <jpi_> but now all my new VMs are kept in the pending state
[15:15] <jpi_> do the "requierement" thing work ? If so is the manual (http://www.opennebula.org/documentation:rel2.2:img) up to date ?
[15:16] <jpi_> my custom variable (load15) is correctly reported when I issue the "onehost show 0" command

However, if in my requirement statement I use only builtin variables (TOTALCPU, TOTALMEMORY, FREEMEMORY, FREECPU, USEDMEMORY, USEDCPU) it works, my VMs are scheduled.

Can you confirm this bug ? If not, can you provide an example of a script to be put in remotes/im/kvm.d and a requirement statement to be defined on the VM template ? Thanks a lot :)

Hi,

Here it is working. In my setup:

MONITORING INFORMATION                                                          
CPUSPEED=2.2GHz
FREECPU=800
FREEMEMORY=16777216
HOSTNAME=dummy03
HYPERVISOR=dummy
LOAD15=4
LOAD30=0.75
TOTALCPU=800
TOTALMEMORY=16777216
USEDCPU=0
USEDMEMORY=0

and in the VM

REQUIREMENTS = "LOAD15 < 5"

Uses that hosts. Note that hosts where the metric is not defined assumes a value of 0. In the previous example hosts without LOAD15 would match the requirements.

I am closing this one

Cheers

Ruben
