Simple script to split VMs on different host - No affinity group
This is a multi-part message in MIME format. --------------040404050008060004030301 Content-Type: text/plain; charset=iso-8859-15; format=flowed Content-Transfer-Encoding: 7bit hello guys, if you are interested, I wrote a simple python script to balance VMs on different host/hypervisor, logic is simple and will search for same couple of vm name and number suffix, odd and even, and it will try to migrate even VM, if it resides on same host where resides the odd VM. For example if VMPROJ1PROD01 and VMPROJ1PROD02 resides on same host, then, the script will migrate only VMPROJ1PROD02. url of script and rpms are on github: http://github.com/amedeos/ovirt-BalanceVMOnDifferentHost and feel free to suggest new patch, enhancement, create a fork... p.s. I haven't use affinity groups, because maintenance of them will become a struggle, and I want *only* to run same project/application VMs with same name on different hypervisor.

just a thought - you can implement this in a more integrated mannger as part of the pluggable scheduler?
yea, if I have the time I will integrate on a new scheduler best regards a Il 31/10/2014 12:51, Itamar Heim ha scritto:

Very nice! You can see examples to integration with the scheduler here: https://github.com/oVirt/ovirt-scheduler-proxy/tree/master/doc/plugin_sample... And some explanations here: http://www.ovirt.org/External_Scheduler_Samples
