Israel I need you to confirm if this VM didn't went through a cluster change. If it didn't it means we have some other place that caused the cpu profile to be null.
The VM is create from template, it did not change cluster. In the beginning of the test we update cpu socket and core, and then start the VM.
Verify with: 3.6.9.1-0.1.1.el6 Host: OS Version: RHEL - 7.2 - 13.0.el7ev Kernel Version: 3.10.0 - 327.30.1.el7.x86_64 KVM Version: 2.3.0 - 31.el7_2.21 LIBVIRT Version: libvirt-1.2.17-13.el7_2.5 VDSM Version: vdsm-4.17.35-1.el7ev Steps: 1. Create VM 2. Hot plug CPU to VM 3. Run Automation tests.
