XenServer - CentOS7 with GUI
-
Hmmm... I would try it without the GUI. I've never done a GUI install physical, XenServer or otherwise of CentOS. There are lots of things that it could be, but as that's an edge case it seems like the place to start. There is so much more to go wrong with all of that GUI running on there and it makes troubleshooting issues much harder because it is more likely to die right away.
You never answered what architecture you are installing as.
Even if you want a desktop environment on CentOS, you would normally install as text and boot to text and only run the desktop for remote users, not on the main console as that uses resources always, not just when people are connected to it remotely.

Does the GUI work for you during the installation process? I never use that either, text is just faster and easier, but that would give some hints as you did that.

Mint Linux and Fedora do the same thing..... Which makes me think it's a XenServer issue.

I'm going to keep asking... what version of XenServer and are you installing PV or full virt?
-
And... what console app are you using?

Doh, sorry. XenServer 6.5 How do I know if I am using PV or full virt?
-
@scottalanmiller Just the XenCenter Console.

Easiest way is from the templates chosen. What templates are you using for these installs?

Other Media.
Oh, try using the ones made for these
That's likely the issue. -
What made you choose to use non-optimized settings for Linux?

The suggestion of the community?

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.

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.
