I have a similar problem creating VM's with the API, but no solution. It seems that by default oVirt uses custom 'Instance Type' ( you can see it if you use the UI to create a VM ). The default RAM limit for custom Instance Type is 4096MB. I haven't found where you can change the settnigs for the custom instance type though.

Hi all, Since engine 4.1 there is new property of VMs/templates - max memory [1] that is required to be larger than (or equal to) memory size. The problem is probably caused by the fact that the specified memory (I assume that value of `memo` is 20480MB) is larger that max memory that is implicitly copied from template (Blank in this case). I can see two possible solutions: * Explicitly specifying size of max memory in the script. * Increasing max memory in the template.

Based on the snipped provided at the beginning of the conversation I assume rest api v3 is used. I'm not sure, max memory property was backported there. @Juan do we have some support for 4.1 changes in rest api v3? In rest api v4 it's http://ovirt.github.io/ovirt-engine-api-model/4.1/#types/memory_policy/at... . <vm> ... <memory_policy> <max>amount in bytes</max> ... </memory_policy> ... </vm>
