Description of problem:

While creating a host for Libvirt, when we select the Type in the Virtual Machine tab and then choose the image-based provisioning method in the Operating System tab, the previously selected Type in the Virtual Machine tab gets removed.

How reproducible:

Always

Is this issue a regression from an earlier version:

Yes

Steps to Reproduce:

1. Create libvirt CR and image

2. Hosts -> Create Host -> In Host tab select libvirt in Deploy On

3. Virtual Machine tab -> select type

4. Operating System -> select Image Based

Actual behavior:
After selecting an image-based operating system, if the 'Type' field is cleared and not set again, host provisioning fails

Expected behavior:
After selecting the image-based provisioning method, it should not remove the type from the virtual machine that is already defined.
