Questions:
-
It doesn't seem like I can input anything and if I attempt to escape it tells me I cancelled the installation. Unsure what this is supposed to look like when it finishes allocating to my VM.
-
How do I interface with the VM to continue the installation process?
-
How do you determine the IP address of a guest from KVM?
You can interface to the graphic console of the hypervisor with a software like virt-manager o other web interfaces; or you can expose the vnc/spice graphical port in this way and connect to it with any vnc/spice client.
Regarding the IP of the machine: if you are using the NAT networking with the addresses released by the host, just look at net-dhcp-leases. Otherwise, use domifaddr.

But, really, don't install a guest in the '90s way with KVM, instead use a proper tool like virt-builder.
The old way of install a guest is completely unneeded in a virtualized/cloud world; instead of installing through an ISO, a procedure that is slow and requires kickstart/manual intervention, you can just use a cloud image pre-built and optimized to run as a virtual guest and inject the customizations (credential, additional software, config) with tools like virt-builder.
AWS and the other cloud providers works this way. -
Did it not give you the option for a virtualization host during the install? I just choose that and all of this work is done already.
If it's the Workstation Edition all of this should be done by default.
-
Also, maybe it's just me, but I think it's a ton easier if you don't use any caps for VM names.
And if you keep the VM OS disks the same name as the VM it makes things easier.
-
Also, I think I saw @JaredBusch mention it, but if you're already root you don't need to run sudo.
-
I posted this about a month ago and has worked out great for me.

I didn't actually do that, it was late and I neglected to remove that part of the instructions. Thank you though
-
So the point of me doing this is to learn how to do it from the CLI and then I can move forward and use a GUI. I need to know everything about both. I appreciate the help. I'm going to reinstall Fedora 25 and start over using @JaredBusch's linked instructions

Sure a Windows guest you have to build that way, and even then you would create a template first so you can clone it. But any Linux distribution can be built with it.

VMnames.FTFY. It's a Windows-ism that is best left behind. Hostnames, filenames, whatever... caps are generally best avoided.

Ya. And I don't get the capitalization of cmdlets. I know you don't have to type it that way but seems weird they go through the trouble of that.

MS has a weird hangup about their use of caps, they always have. It makes me feel like an original Apple ][ junkie is still running much of the show.

Readability. That's the whole point of capitalization in this sense. I don't carr either way, but if you are combining words, capital letters make it easier to read.

Functionally, with Microsoft it doesn't make a difference in just about every case... which is how I think it should be. If I capitalize something, it should not change how it functions... but that's just my quick opinion.

Just avoid making long, weird names for things

I prefer accuracy and not the "soft" approach. I like to know that I have to get it right, not close. It works, but it's weird to me. Having certain ASCII pairs turn into the same thing to the filesystem feels really hokey and weird to me. If I mean X I'd type X, not x.

I find it even stranger that it preserves case, but doesn't honour it. So it is storing the full ASCII set, then processing it to compress it to a smaller set of characters. But it is not consistent, it uses caps sometimes, and not others. And it is very confusing when it interfaces with other systems and so things like the filename it trains you to "type anything" but you go to use a URL and caps matter.

That depends on the web host.

I know, but it's confusing for end users to have some things be case sensitive and some not. Windows users are especially prone to not knowing the difference between different interface locations and Windows 10 makes this worse by making the file search field also kick of a web search.
