Description

The idea is to be able to tell OpenNebula whether a group of VMs should be placed in the same physical host (affinity) or each in a different host (antiaffinity).

The best fit for this request is to handle it at the OneFlow level. A template for a VM that participates on a Service would be able to include:

AFFINITY_TEMPLATE_IDs=<templateid-A>,<templateid-B>
ANTI_AFFINITY_TEMPLATE_IDs=<templateid-X>,<templateid-Y>

-- This VM would then be placed by OpenNebula in a physical host where VMs belonging to the same service AND coming from templates ID=(A or B) are already running or will be placed by OpenNebula afterwards.
-- VMs from the same service coming from templates with ID=(X or Y) won't be placed in this physical host.

History

#1 Updated by OpenNebula Systems Support Team about 7 years ago

It would be more useful to incorporate this into the core of OpenNebula and scheduler so that it supports the resched functionality, and taking into account the count of VMs as well.

AFFINITY=”SELF<2,X=1,Y>1,Z=0”

1. less that 2 of my template id
2. exactly 1 X template id
3. greater than 1 Y template id
4. none of Z template id

Additionally, using an AFFINITY_TAG may be more useful than the TEMPLATE_ID.

For example:

AFFINITY_TAG = database
AFFINITY_RULE = "database < 2"

This would allow for affinity rules to work across different templates that specify the same tag.
