KVM / Red Hat Virtualization Management
-
My current job uses both VMware and Hyper-V; thus, I'm becoming more familiar with the management software: vCenter for VMware, and Virtual Machine Manager / Failover Cluster Manager for Hyper-V. For my day-to-day activites, I use those applications for deploying VMs from templates, moving VMs to different hosts, and editing the hardware of a VM.
This link lists several options, but I'm curious if there's a de facto standard for managing a KVM cluster? Or do folks just use Virt-Manager for everything? Also, if any of you use whatever Red Hat itself offers for virtualization, do they have their own management application?
-
For KVM I use virsh and virt-manager. If your storage is already shared, virt-manager is just as easy or easier than the other management tools for managing everything.
KVM just has a little more legwork to get a cluster up and running. I think it's easy, but most people just won't have the experience to do it. (Ceph, gluster, and the like).

RHEL Virtualization is based on KVM.
My assumption is that they would have a better management interface is all, and maybe a simpler setup process for getting a cluster up and running.
Fixed for clearly not being and to use words today.

Although I want to now reach out to RHEL and tell them to fix this. . .

Umm what? RHEL is not based on KVM. RHEL is the OS.

Yeah. I have yet to find any kind of screenshots or demo videos of Red Hat's solution, and information that seems promising is hidden.

Doh words.
I meant RHEL Virtualization is based on KVM

If you must use a web interface for KVM, There's WebCloudMgr (used to be WebVirtMgr).. https://github.com/retspen/webvirtcloud
I used the WebVirtMgr, but haven't tried the Webvirtcloud yet since I'm pretty much happy with using Virt-Manager.

Cockpit is what will, eventually, be the web based management tool. It's not quite fully ready yet. The really lacking thing in it right now is new VM creation.
Forgot about it in my first response, doh!

That looks a ton like XO.

oVirt web management UI looks very similar to what RHEV uses.

I'm surprised Red Hat doesn't seem to be promoting whatever they use for managing RHEV. I figured they'd try to lure folks away from VMware or Hyper-V with a slick interface

Mist is a good one but it's more geared towards cloud deployments.
I've used Ansible and Terraform to do deployments as well as Virt-Manager and virsh. It's all in what you want.
This is all assuming that you're using QEMU. KVM exists without QEMU which is how GCP and AWS run KVM.
For Firecracker (AWS) it's all REST API management.

Looks like the answer is "no"

The default answer does exist, Virt-Manager. Cockpit works, but as @travisdh1 mentioned is lacking a few features to make it the solidified "go-to" solution.
If you need more or want something different then you'd look at alternatives.

The feature I see missing from Virt-Manage is the click-to-make-this-vm-a-template button and then click-to-deploy-a-vm-from-template button. What I do instead is just make a VM, power it down, and clone it, which, for the most part, seems behave the same.

So, by your description, you can't make templates of VMs?

@wrx7m I thought you could do this using virsh or am I mistaken?

I haven't used KVM yet. I am not sure.

In Virt-Manager you would just clone the VM once it's powered off.
So build your Template VM, with all of the settings you want. Name it something identifiable as a template and just clone, clone clone.
I'm not sure if there is a specific "Template" feature though, at least I'm not seeing one here.
