Description Polina 2022-06-20 11:08:54 UTC
Description of problem: we have two problematic flows here  - for running (Step2 )and not running VM (Step1).


Version-Release number of selected component (if applicable):
ovirt-engine-4.5.1.2-0.11.el8ev.noarch

How reproducible: 100 %


Steps to Reproduce:
1.Configure a not running VM with CPU=2 numa number = 2 and no host pinning. Edit VM - remove the numa number (put 0), then pin a host. = > 

Actual result: pinning the host automatically returns the numa number.
Expected: if I removed numa num , I don't expect that host pinning will revert this change. this is wrong.

2.For Running VM it is more critical : Run a VM configured with 4 CPUS , no host pinning and numa number = 2. Edit the running VM: replace numa number by 0, pin a host, note that the numa number is returned to 2, put 0 again. OK in the edit window. GET "Changes that require Virtual Machine restart:" message , OK.  Shutdown VM , start => it still has numa number 2.


Actual results: Restarted VM has initial numa number configuration 
Expected results: VM must have numa number 0.
