Description of problem:

While creating an image in the Libvirt compute resource, any invalid value entered in the UUID field is accepted.

How reproducible:

Always

Is this issue a regression from an earlier version:

Yes

Steps to Reproduce:

1. Create Libvirt compute resource

2. Infrastructure -> Compute Resources -> select libvirt

3. Create Image -> Fill in the required fields and enter an invalid value in the UUID field.

Actual behavior:
The UUID field accepts any invalid value and still allows the image to be created for the Libvirt compute resource.

Expected behavior:
The system should not accept invalid UUIDs and must accept only valid UUIDs.
