I'm happy to have another article but there are a few points that are clearly wrong, and I'm only at "Hyper-V" within the article.
Its free edition is only available for Windows VMs and that too without GUI.All editions of Hyper-V are free, only if you choose to Install Windows Server # and enable the Hyper-V role are you forced to purchase a license. And even here, Hyper-V is free, it's Windows Dom0 that you're paying for in this case.
This approach is generally looked down upon when deploying as well as it causes licensing complications especially if you have any DR plans.
Wow, that's not just wrong, that's like "I'm not familiar with virtualization at all" wrong. Those are such basic "noob" misconceptions. Even on places like SW that's not acceptable.
-
What I just noticed even more so is that Hyper-V "free" only runs Windows VMs. Which is completely wrong, it'll run linux, BSD, Mac and Windows without issue or complaint.
So there is even more wrong with the article than what was just in my head as I was typing. . .
-
How about this...
Not only is the writing not in correct English, every SINGLE point is wrong. Every. Single. One.

Yup, there is no limit whatsoever. He's just making this stuff up. It's like he went to SW and read every common misconception that people are mocked for believing and wrote them into an article.
-
Look, he didn't even get the product name right!!!

Other than a few product names right, I've yet to find one thing that IS correct in the article, literally. Not one thing correct yet.
-
He didn't even correctly copy this. It's Kernel-based Virtual (not virtualization) Machine.
-
I'm getting the article pulled and rewritten. I reached out to make sure someone saw it.

Yes the skills required to use KVM on a production level is different, but it is no different than managing any other Hypervisor.
Yup, it's easier to use in every way I can think of. You don't easily get agentless backups for the VMs, but that doesn't have to be a deal breaker. Other than that, KVM is easier and better.

I would question this as a "truth" is might be easier and better but you have to evaluate and discuss the options before just blindly picking a statement like that and applying it.

Why are they letting people write articles on subjects they are completely unfamiliar with?

I just did a new install this week and it turned out actually easier than even VMware at this point! Which is amazing because Vmware is so easy.

It does actually get agentless backup, it's just not a very good one. I have agentless backups on my KVM systems. Better than VMware Free, not anything close to Hyper-V.

For those new to KVM: What is the general consensus on having a Fedora-based KVM host that boots and runs from a SSD but uses a software RAID on spinning rust for the VM storage?
-
@obsolesce I was wondering about that. When she introduced the writer she did so saying he had some mvp title or something like that. He should know precisely what is wrong and right with the technologies he was talking about. He reminded me, instead, of a plain writer who tried to research something for an article and just got it all wrong.

That is one option. Why not make the software raid bootable, install Fedora on a small partition, and use the SSD as cache for the LVM volumes?
-
@brandon220 completely wrong. Instead, use a couple of spinning rust for the Hypervisor and the SSD for the VMs.

In theory you want fast disks were the workload is. So if in doubt just use fast disks for vm not for the hypervisor
-
I have some small SSDs that are not big enough to store VMs but would run a host machine very efficiently. I realize you want the performance where the workload is. Lets forget about the SSD for a minute.... Is software RAID in Linux acceptable to use? I always use hardware RAID controllers in servers but wanted to venture into trying software RAID.

The host doesn't do anything, so SSDs have no benefit besides making things go faster that aren't VM related... such as faster Fedora updates, which are already fast... and other minor things.
Software RAID is good in Linux. I'd use LVM.
