Cockpit is there by default, no effort there.
Only if you installed Fedora Server Edition.

It is not there by default if you choose a minimal install. But that was not the point of this post.

I have to dig more into this - by simply choosing the option Scott pointed out - I now have a machine that's logged in - but no clue what to do next? in XS or VMWare or Hyper-V I'd be presented with a graphical display telling me to download something from some IP address (well OK not Hyper-V), and install XC or VMWare whatever it's called - or I think starting with 6.5 visit the webpage built into the hypervisor now, etc... but with KVM - nope, just a fedora prompt and me now going to search for 'what next'.

When it finally rebooted, the console should tell you to go to https://ip.add.ress:9090
right above where it shows login

right baove where it shows loginaww - it does not say - GO TO...
But it does say
webconsole: https://localhost:9090/

Thanks I glossed over the Web console bit.
I'm assuming you added the host name during install which is why it's there in your listing? I didn't do that, so I have the default.

Well my KVM host only shows localhost on the console screen, but when I SSH into it, I see the names. which is weird.

No one has ever said you didn't have to think or learn nothing to use KVM. Just that it is easy by comparison.
Compared to Hyper-V this is much simpler. Debatable on how much easier than VMWare as I have not installed it in years now.

OK it was braindead'ish easy to install and get to the console. Though - something a bit more in your face about the web console like XS would be nice.
As for what options to choose to get a KVM host - Scott's example above works fine, even from a Netinstall ISO - choose Fedora Server > Headless Virtualization (only selected option)
and you end up with something. I don't have time now to play with it, but I will tomorrow. -

We tend to, because it is part of setting up the static networking, which you often do with hypervisors. not always, of course, but it is common.

Glad to see you stopped being such a die hard Xen fan
I remember you fighting tooth and nail against KVM on spice forums. -

I remember you fighting tooth and nail against KVM on spice forums.Not so much a fan, as choosing the best products at the best time. Xen was superior for a long time. KVM had a lot of deficiencies. KVM has pulled ahead in a lot of ways. I don't choose or promote products because I like them, I do so because I believe that they are fitting the specific need best.
That means, that naturally, as the products change over time their place in the universe changes. And nothing is for everyone. Xen still remains a viable player, KVM just makes sense for more shops, more of the time.

@scottalanmiller my guess is, when Amazon started running KVM (as was expected when they hired Anthony Liguori), that was the last straw for you, because your main argument against KVM has always been "but Amazon..."
But nevermind me, I'm just having fun here. Been riding the KVM train since before it was generally heard of after all

Amazon still uses both, even now, actually. But that was a factor, to be sure. Amazon's drop in investment meant that Xen had way less future than before. And Citrix serious tried to burn it down, which really sucked. And getting the Xen community to do XCP-NG took a year longer than it should have, so the opportunity wasn't as ripe. And KVM just pulled ahead in a lot of ways, the Linux vendors all adopting it so heavily was a big factor.
XO did a lot to keep Xen on the table, and it is still very viable and good today because of that. And it still might make a comeback. But the lack of serious development around full PV, and the incredible rise of LXD has made Xen's space less viable.

KVM has been the same since ~2013 she I started with it. The only difference is Cockpit. All the other tools have existed for quite some time.

Under the hood to some degree, but tooling and market support have changed a lot. KVM was doing okay, but wasn't the big leader in 2013 like it is now. It's place in the market is important, too.

What tooling? Libguestfs, virsh, and Virt-Manager have been around forever.

I've not tried XCP-NG/XO since they released it. But my go to is ESXi.
HYPER-V I just found a pain in the rear to admin. Just found sometimes I could manage it with manager built into windows, then when trying on my laptop it wouldn't then it did, then when on VPN again hit or miss.ESXi For me. Is the simple install. Boot. Hop onto the web interface to administer. From there create and change VM's.
Like other solutions backup is separate.
At the moment I'm using Unitrends free appliance and doing agent less backups as all the VMs are Linux based so simple.But of course this is my preference and experience.

Cockpit doesn't let me setup the networking I want though.
But VMM does.
Once changed, cockpit, of course shows it. But is stilled greyed out.
