Best practice partition & LVM for KVM

For a KVM server or Linux VMs, wouldn’t it be better to use swapfile instead of a swap partition?
That’s the general consensus today.

@tim_g another one is because Dell always issue RHEL package which normally is compatible with centos. Never try it with fedora, so not sure it will run well. ie. Omsa dell.
Related to KVM, what fedora can offer that CentOs cant?
Fedora is dramatically more modern. Years newer than a CentOS

/root (ALL remaining space)
/root != /
/root is home directory for root user
/ is root directory -

Even Nutanix (I think) also runs CentOS:

@fateknollogee yup CentOs normally has better wide range of support. Thats the reason i stick to it even it is less modern than fedora.

For me, by default, I use Fedora first. Unless the application that I’m using specifically requires the use of CentOS.

Define "wide range of support"? One of the reasons a lot of us don't use it is that you have to work around the lack of support all of the time.

Exactly. CentOS is outdated to a point where it causes all kinds of performance and functionality problems.

You sir, are certainly entitled to your opinion...A lot of folks (aka Nutanix customers) in the market would certainly disagree with you!!

How would you know since they are barred legally from disclosing problems? Nutanix uses unethical means to silence complaints and comparisons of their devices. So the only people reporting about them are either filtered or haven't compared against others and don't have any idea if they are good.
Remember, that "lots of people like something" is zero indication of its value. If they didn't compare cost, performance, or reliability against other options, their opinions have no meaning, none.
Loads of people like inverted pyramids, RAID 5, no backups and other insane things. Obviously that lots of people like something doesn't mean anything, most people aren't very smart. In fact, if most people do something, it's an indicator that it is probably promoted by marketing, not value. I actually made a video about this just in the last two days!

Remember that customers specifically are in a position where telling that Nutanix is bad is financially not in their interest. The last thing most people want to do is admit that a giant financial decision that they made was wrong or that they got scammed because they didn't do their research. It's why asking customers about things rarely tells you anything useful. Once people buy a product, especially big ones like this, they now have a shared benefit from promoting it to make their own old decisions look good.
We see this every day on SW of people talking about how much they like something, both product and decisions, that are obviously bad and get torn apart and they have no defense of them. They like them because they were told to like them or it is in their interest to like them, not because they like them in a way useful to anyone else or that the idea or product was any good.
That misunderstanding of how to evaluate things that have already been purchased is where this article came from...

@scottalanmiller How is this different from you "promoting" @scale ?
If Nutanix offered you the same deal you got from Scale, would you turn it down? -
Another nice thing about using Fedora instead of CentOS is the updated VM guest tools. For example, I don't have to rely on Microsoft to release newer Linux Integration Services for CentOS.
-
btw, does @scale use Fedora or CentOS for their appliances?

Two, Nutanix has offered me trips and stuff that Scale has never offered. Nutanix has made a real effort to have me not keep mentioning how they shut down negative information about their products.
So, I'm confused what you are saying. It's different in every conceivable way. One I promote because I believe in it and promoted before I ever knew the people involved. The other is unethical and should never be even considered for use in a business and has legal reasons why.
What makes you associate the two?

I'm not sure it is either. It's an appliance, I don't think that they list it anywhere.

And DRBD, and Starwind, and Hyper-V, and HPE Simplivity....
Notice a trend? I promote all kinds of good, and competing products, and point out one that specifically is a problem in that field. One that is well known to be less performant, higher cost, under financial strain, and hides its problems by silencing critics.
I hope that that clarifies just how different these things are.
