Bug 1677603

Description of problem:

Discovery kexec is not working after upgrading Satellite to 6.4 with Nutanix Acropolis Hypervisors. 


Version-Release number of selected component (if applicable):  6.4


How reproducible:  Always

Steps to Reproduce:
1. Discover a host using the latest foreman-discovery image
2. Enable ssh on the host and run "journatl -f" on the host so that we can get the logs related to kexec
3. Go to "discovered hosts", fill up the form and hit submit

Actual results:

kexec does not get triggered properly and hence the system reboots.

Expected results:

kexec should get triggered and put the system into build mode.

Additional info:


Host logs shows that kexec gets initiated, but shows no errors:
