Not that I'm aware off.
The only thing I saw was that the FQDN during the engine-setup was changed to a hostname
from the company where I host the main website. I gave the FQDN during the minimal
install ovirthost01.<mydomain>.nl and engine setup had changed it to
<random>.<domainhosting-company>.nl
I changed it back to my given hostname at that point in the engine setup.
But if this explains the error I get, then I will reinstall my server with an internal
domain name that can't be found on the internet at all.
