Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1589779

Description of problem:
In a host creation form, when I select a RHEV CR that uses APIv4 and select some image in the OS tab, I get incorrect number (1) in Cores field in the VM tab. This does not happen with APIv3. I guess this is caused by actually using processor count instead of core count.

Version-Release number of selected component (if applicable):
Sat 6.4 snap 7

How reproducible:
Deterministic

Steps to Reproduce:
1. Have a Sat, RHEV with some template with cpu_count!=cores!=1, this RHEV added to Sat (with apiv4==true) and Image assigned to it, using that template
2. Hosts -> Create Host
3. Select RHEV as provider, go to OS tab, select arch + OS, select Image Based
4. Select the image, go to VM tab

Actual results:
Cores==1

Expected results:
Cores should be number of cores set in the template
