Xen and KVM - Who is using what and why?

Let me re-phrase the question: Was the move to Scale done because it was technically superior to XS or was it financially motivated?
It's really apples and oranges. One is part of a solution, one is the full solution. If you used any other system, would you ask the same questions?
We are trying to break down something large, which is an architectural change drive by a change in support and use paradigm, and applying it to the underlying hypervisor component.

@JaredBusch If they got paid to make the move, more power to them.
Are you saying KVM is not "superior/better" (insert your fav adjective) to XS? -

We've primarily moved to KVM before we are running Scale HC3 which has it built in under the hood.
So you like KVM these days better than XS?
Odd conclusion to draw from that statement.
Not entirely. You moved to KVM before getting the Scale. If not because you like it better, then why?
No, we did not. We use KVM exclusively with Scale as an artefact of the Scale system. My wording must be odd above,
Well, the site is running on KVM also.
It is, it's true.

They were not paid, but they also did not pay for it.

I don't think that either he nor I have said anything of the sort, in either direction, in the thread. No one has gotten to that point yet. We are still just trying to explain the meaning of the answer to the initial question and dealing with the incredible amount of ensuing confusion.

@scottalanmiller is not saying that at all. Anyone else is just throwing poo like a monkey.

If I was to back up.... I think there is something important being danced around and that is that while someone might prefer one hypervisor to another, largely they don't matter today (except for VMware's licensing aspect.) Hypervisors are commodity and they are all fine. The ecosystems around them are vastly more important. Talking about Xen vs. KVM is academic and nearly esoteric. What matters is what you want to do with it and what ecosystem is providing the tooling that you want to use.
-
It is interesting for IT people to discuss the merits of Xen vs KVM, and I'm happy to do so, but at the end of the day, the quality or features of Xen vs. KVM are almost never relevant to a business decision around which we will use in a deployment outside of a lab environment.

Let me try to "re-phrase" the question...
...btw @JaredBusch I like the "poo as monkey phrase..."A lot of folks on this site have praised/raved about the XS/XOA combo.
Is KVM worthy of being looked at?
-
It is not unlike the Linux discussions. People often ask me "If you prefer CentOS, why did you deploy Ubuntu?" And the answer is so obvious that I'm always confused by the question - because the thing that I needed to run runs best or only on Ubuntu.
No matter how much I prefer CentOS, it doesn't mean I would chose it over the better business choice, the differences between CentOS and Ubuntu are simply too small.
-
I think the original question would make more sense like this.
"If there was a vendor who offered a Hyperconverged solution like the HC3, but with XenServer, would you have picked that vendor over scale and why?"

That's why we praise it, because it's a combo (or bundle.) I've even proposed calling it XS/XO (btw, many of us have never used XOA, not sure how many people are promoting that) instead of XS to make it clear that it is the combination that makes it make sense.
KVM is a great product. But you can't compare XS to KVM let alone XS/XO to KVM. If you want to do that, you need to determine your entire KVM stack to compare against. For example, is Scale HC3 (KVM) worth comparing to XS/XO (Xen)? Yes. Those are far more comparable items.

"If there was a vendor who offered a Hyperconverged solution like the HC3, but with XenServer, would you have picked that vendor over scale and why?"
And it would still come back to... it's the solution that matters, not "how they arrived at the solution."

This is, in the most literal sense, getting caught up in details "under the hood."

There is a bit of fanboy cult thing to some of the the XS love around here.

As @scottalanmiller said above, it's the combination of the tools to make a robust solution that create fanboys.

Really a WTF moment to start off your entire involvement in the thread.
Scott said 'before' which lead to my question.

"how they arrived at the solution" is a big part of the equation?
Would you have arrived at the same solution if the cost was $xxx? -

Time to start the Hyper-V cult?

Absolutely not. Any cult is bad, Christian, Muslim, Jewish, Wicca, Cthulu, wtf ever. This is business not religion.
