Description Jon Benedict 2016-05-12 18:17:02 UTC

Description of problem:
Currently, in order to properly "seal" (make a VM generic in preparation for cloning or template), it is a manual process or a painful RHEV-CLI process in order to use virt-sysprep. In RHEL+KVM (or CENTOS, Ubuntu, etc), this is not an issue. Our own Red Hat documentation suggests a painful manual removal of SSH keys, UDEV rules, MAC addresses, system id, and hostname. It is the complete opposite of automation.

In order to run sys-virtprep in RHEV, you have to go through the trouble of deploying the RHEV-CLI, locate the the disk image, activate the logical volume, run virt-sysprep, deactivate the logical volume, then create the template back in RHEV-M. 

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

How reproducible:
Create a VM in RHEV. You are unable to utilize `virt-sysprep` or other libguestfs tools in a convenient manner.

Expected results:
Have an option in the template tab or VM tab to open a dialog box for sealing options.

I ran into this same issue at a customer site this week.

The process of building a template does seem archaic in comparison to the larger story we're delivering around hybrid cloud automation.

It would be helpful to have this functionality delivered from the UI for RHEL guests.
