How reproducible:

Only on Customer Red Hat Satellite.

Steps to Reproduce:
1.Create Libvirt compute resource on Satellite Web UI
2.Test connection working but when submit is clicked getting above mentioned error. 
3. Also on Red Hat Satellite server and KVM server below hung process is present.

Actual results:
