[ovirt-users] How to use virt-sysprep

[Joel Diaz]

I ran yum update on my three host and the engine VM so I believe an up to
date on all the packages. How can I check if I am on version 4.1.2?

I restarted the httpd and ovirt-engine service after the updates, but still
don't the seal option.

Thanks,

No , you're looking at the right place. This feature got in pretty late in
the release cycle of 4.1, so it is available from 4.1.2. Maybe the version
you are using is lower than that?
