What made you choose to use non-optimized settings for Linux?

THIS community? What reason did people give for not using the optimized settings? They are there for a reason, to make sure that you have the right drivers, best performance, most stability, etc. There are cases where you need to not use them, but it means you have to worry about the drivers and such yourself. I bet you will find using XenServer as designed that you will get good stability and performance.
CentOS and Fedora will use the same template. Ubuntu and Mint will both use Ubuntu. Mint is Ubuntu 14.04.

You said that you use it?

That's a Gnome 3 error. How much RAM is assigned to this VM?

That's a lot different than recommending it. I use it for specific things. What was the context around that, though? What was I saying that I use the other media for?

Just, just found it from Google. I certainly wasn't recommending anything. The reason that I was mentioning it is because we often install 512MB systems (always text based.) And often OSes that are not supported by XenServer officially as well. So there is a reason for it. But if running a stock CentOS 7, I would normally look at at least starting with the templates. At very least, worth testing them here.

I use it a lot because of the same reason. The template I think gives 2 GiB by default, which is a lot for what I'm normally building.
So here's another question according to their documentation:
The Linux templates create Pure Virtual (PV) guests, as opposed to the HVM guests created by the Windows and Other Install Media templates. Other Install Media template Linux installations are not supported.
So does installing XenTools give you PV also, or do you have to use a template?

Should be plenty, I doubt that it is a memory issue. Most likely a driver one.

You need to the template. Drives cannot make something PV. PV is unique to Xen and the Xentools only exist for when you are not PV.
If you are doing a non-templated install, then you need the XenTools installed separately.

I'm building one right now, I'll let you know what happens.

Trying again with the correct template.

Right that's what I was asking. If I use other media, and then install xentools from the iso, is it PV then or still HVM?

I wouldn't say "correct", but let's say "standard." It's the most common approach to handling those workloads. Nothing wrong with going non-PV or non-template, but it means more work on your end, like getting the XenTools installed and dealing with driver selection.

Didn't I just answer that
Drivers can never make something PV. PV vs. non-PV are different target archtictures, not a different selection of drivers. Installing the XenTools is required for HVM only. If you have a PV install, you don't need special drivers at all.
The entire point of XenTools or any PV Drivers like that on any platform is an attempt to mimic true PV. But if you install as PV, there is no purpose to pretending to be something you already are.

And now my ISO will not boot..... WTF?

Any error or just a blinking cursor?
