Description of problem:

• Create new host fails with the following error:
  "Failed to create a compute LOCATION hypervisor (Libvirt) instance hostname.example.org: Error saving the server: Call to virDomainDefineXML failed: unsupported configuration: VNC password is 16 characters long, only 8 permitted"

Version-Release number of selected component (if applicable):

• Satellite 6.12.4.1

How reproducible:
100%

Steps to Reproduce:
1. In Satellite UI, navigate to Hosts -> Create Host
2. Complete the form and select a Libvirt resource in the "Deploy On" field
3. Click Submit

Actual results:

• Create host on Libvirt compute resource fails and displays error in the Satellite UI.
• VM disk is created on the Libvirt storage resource but not the VM itself.
• Backtrace is generated in /var/log/foreman/production.log
