Wrong validation when creating image base host on ovirt
When trying to provisioning host from compute resource image after getting a validation requesting to add IP address, and adding the IP address, submitting returns a validation about missing mac address.
Steps to reproduce:
1. Create ovirt compute resource and add an image to it
2. Create a host and select the image in operating system tab
3. Fill in everything including domain and subnet in Interface but son't add an ip
4. Save and get the missing IP validation error
5.Fill in an IP address and try to save again
There will now be a message that mac address is missing even though it's still marked as deployed on ovirt and not bare metal.
