I got triggered cause there can be only 1 KVM MASTER
It's weird that you're attempting to take the KVM Master role with a GUI install
Why is that any more weird? The CLI is still there to be used, but as far as a tool goes, a GUI is just another one. . .
It's wasted resources. I'd think the KVM Master would be as efficient as possible.
If a tool is needed, why would it be wasted resources? I get what you are trying to get at here, but a tool is a tool is a tool.
If you need a GUI to do something (whatever it is) and it's the best approach "you" know then why bash the tool?

So my old users who say they can't operate a computer shouldn't learn the right way to file things digitally. We should be okay with her using paper because she understands that? I understand what you're saying, but how far down that rabbit hole do we go?

The Virt-Manager is being hosted either on a VM or on a desktop. It's not being hosted as part of the hypervisor. Think SCVMM, Hyper-V Manager, XenCenter, or vCenter.

Why would your user be the administrator of the computer? Why are CLI's the golden child tool, and GUI's are the bastard tools?
My point is it's a tool to be used, why not use it if it's available?

It's just an argument for learning the most efficient/best way to do things. I have a lot of failures and some successes with my learning, but I am learning how to do things in the most efficient way I can.
Example: We could start installing hyper-v as a role because i don't know powershell, but the reality is i should learn powershell to manage hyper-v anyway.

The argument is flawed though.
Tools are only meant to make the process efficient. You're stating that using a GUI is counter efficiency. Which in terms of resources required to use the GUI, makes sense.
But the GUI it's self is there to eliminate wasted time remembering powershell (and human error) by providing a button to start a specific VM etc.

I guess it turns into an argument of what is worth more: your resources or your time? It would be on a case by case basis, but I'm sure that you would be correct in some cases.

Web server
PHP/Python
Node JSAnd those stuff that KIMCHI use

I'll put this in my test environment and check it out. Thanks

Fixed some typos and made it more clearer article. Also posted 2 Centos logos for dominance.

I always thought it was Fedora > RedHat > CentOS.

It is. Fedora is the original. RH is more or less a frozen version of Fedora. CentOS is a code recompile of RH.

Kimchi and all the stuff it requires to run barely uses any resources. We're talking tens of megabytes, almost no CPU, barely any RAM. I'm not using any 15-year-old servers, so they can all handle that tiny extra bit without it having any impact whatsoever on running VMs or the host.
I do agree with installing the web services on a separate device on the perimeter network if setting it up to be accessed from the internet, and having that connected to your Host via another NIC. But I highly recommend keeping selinux enabled. I don't see why everyone always disables that. I always keep selinux and firewall enabled, even on internal-only servers. Banks don't only lock the front door and keep the vault open. They lock both.

Then why did you permanently set it to permissive for

It's way better than putting SELinux in permissive mode or disabling it altogether.

But from a web server, that is the single largest attack vector. why do it? Instead properly set httpd_t_rw on the select files or directories that need it.

True, but see above.
