@scottalanmiller so, your raccomandation for deploying a KVM host is fedora 26, because KVM it is RH baby and F26 is the most recent one?
That would likely be where I would go. Suse supports KVM pretty well, though. Either is fine. But definitely Fedora over CentOS / RHEL. I've stopped using them anytime that I have the choice. We've almost completely replaced our CentOS 7 boxes with vastly superior Fedora 26 boxes. There are a few cases where CentOS still makes sense like for Zimbra hosts. But by and large Fedora makes the better sense.
Those aren't hypervisor hosts though. There's a difference between state machines running Fedora and your host that the state machines are running on running Fedora.
Right, there is a difference, but for both you want stability, performance and features. I'd want Fedora in both cases.
I've had Fedora upgrades not go smoothly. So if that happens it's less stability than CentOS, esp since it's every ~8 months.
How have your CentOS updates gone? I've had far better luck with smaller, incremental Fedora updates.
Never had an issue with updates. And I'm not talking normal updates. I'm talking release upgrades that have removed features and broken backwards compatibility.
State machines sure run whatever the newest best because it's easy to rebuild. The host needs stability which I have had less with on Fedora than CentOS.

Right, and I feel that Fedora has the edge on stability now. Hence why I want Fedora under the hood. I don't want the massive LTS upgrade risks that CentOS brings. Not that it has no advantages, but I don't feel that they outweight the benefits any longer.

For purposes of host stability I prefer Fedora over CentOS where the applications on top allow for it.

And you've never answered the question I've asked you before. What are you using for central logging on Fedora?

We've moved away from central logging temporarily during a major overhaul internally. Are you seeing issues with Fedora with central logging?

You pretty much can't unless you pipe journald into syslog and ship out that way. Which is 100% going backwards.
I don't like the way systemd handles logging (in Fedora).

Yeah, there have been loads of complaints about how Fedora is handling a lot of that stuff (and some other distros, too.) SystemD is not doing Linux any favours.

I like systemd if they would just leave the logging the way it is in RHEL/CentOS. It's nice being able to search specific time spaces but there isn't even a messages file in Fedora anymore.

Have you taken a look at StarWind V2V Converter?
Thanks for mentioning StarWind, just wanted to make an addition of the features available in the V2V Converter which includes a Windows Repair Mode which may become useful in the process of converting to VHDX. The end result would be the automatic VM adaptation to the given hardware environment, negating any possible compatibility problems.
Take a look here - https://www.starwindsoftware.com/converter for any other additional information. -
Got back to this yesterday. Running on CentOS7 as a base (best of the default options the hosting provider has/had.) Easy management through the remote virt-manager and ssh.
@Tim_G turned me onto Kimchi as a secondary management interface as well. I've successfully installed wok and kimchi, but haven't opened the port yet, will get that done tonight after grabbing an ssl cert.
Also got the first vm uploaded last night, tomorrow looks to be a big day in my home lab.
