Trying out Xen
-
@scottalanmiller I wouldn't be surprised if it's some kind of Windows copyright nonsense or something of that nature.

I can't imagine how that would be even possible. How could Microsoft have a copyright on the Xen console?
-
@scottalanmiller Oh I was thinking more along the lines of some protocol that was used, something like that. But then again, I have no clue what I'm talking about.

The protocols are all Xen protocols. It's Xen talking to Xen. Xen is open source.

@scottalanmiller I guess I just always assume if they a company has developed it and can't move it to another platform, it's because of some legal matter. Kind of like Apple with their crazy patents. Such as their patent on "Touch screen device, method, and graphical user interface for providing maps, directions, and location-based information"

If Microsoft had the ability to "own" anything you made on their OS, no one would ever use it.
Apples doesn't have anything like that either. No one does.
Citrix just has a lack of resources or wants to port Windows only code or something simple.
When people can't move between platforms 99% of the time it is because they don't have the manpower and 1% because of a technical limitation making them have to develop something completely new.

Please remind where the difference between Xen and XenServer - I take it Citrix still owns XenServer - but what? it's free now?

Xen is a "kernel" for a hypervisor. XenServer is a full hypervisor distro. Xen can't stand on its own, it needs to be assembled. Xen is analogous to Linux or Asterisk, a building block of something bigger. XenServer is analogous to CentOS or FreePBX, it is a full product.
Citrix does own XenServer by name, but the code was open sourced (there was almost nothing that Citrix owned anyway) and is now managed by the Linux Foundation who also makes XCP (the non-Citrix version of XenServer) and Xen itself.

@scottalanmiller I have a test XenServer up and running. Thanks again!
(P.S. to anyone who wants to try. Don't use a CentOS 6.7 iso for a VM. I used it just because I had it from trying to install Xen. The networking will not work and you will attempt to fix it for about 3 hours. Then begin to question yourself, because you can't seem to figure out a simple networking interface in XenCenter. Then you will install Ubuntu and it will work fine.)

I'm really shocked that CentOS does not work. We do this all the time and it has always "just worked" right out of the "box".

I haven't tried 7. I saw someone else had an issue with 6.x so I figured I'd try a different iso.

We've been using a lot of CentOS 6 over the years.

I probably screwed something up. I'll try tomorrow just for fun.

Where you trying PV or HVM?

Truthfully I don't know. I didn't see an option for either. I clicked on New VM, then selected CentOS 6 from the template list, gave it a name, picked my ISO from the NFS, picked the server, set cpu/memory, set storage, set network, and then finished.
-
It's always HVM by default but some templates might go to PV.

@scottalanmiller What do you recommend for backups? I'm only going to have a couple VMs running. Should I just rsync everything on each?

You can do that. If you are going to rsync the contents of the VMs, that's fine. If you want to rsync the entire VM you need to either shut it down or snap it first. There is a script that people use that can do backups for XenServer too, that is free. @DustinB3403 should have a link to that as he is using it.
-
NAUBackup is a great script for Xen. GitHub Link
Anyways just wget into /patcher and it can be run right from there with just some small adjustments to the file paths.
When I started using it I even made some recommendations to the comments to clear up what was being said. If you have questions don't hesitate to ask.
