- Can we use name of OS in os-variant without minor version, like just
centos6, centos7, rhel7? Output of command "osinfo-query os" has only exact
version of OS, but I met examples with OS just with major version. Does it
correct, will it work?

or "auto" or..?
- How does parameter "auto" work? Will it work for for converted images
from VMware?
- What is the best way to determine OS from VMware? virt-inspector or
somehow else?
I did not find in documentation these information.
Thanks in advance!
