Trying out Xen

@scottalanmiller I just downloaded it and am putting it on a usb. What do you recommend for a client? The only Windows machine we have is my wife's old laptop. Will virt-manager work or should I use something like OpenXenManager?
You CAN run it from USB, but it is not simple like VMware, sadly. That's something that they REALLY need to work on. It can work, but it is a huge pain.
You can virtualize XenCenter on top of XenServer, but obviously that has a few limitations (can't start itself, for example.) You really should use XenCenter to at least get started with XenServer, you can test out any other clients that you like after seeing what the "official" one is like. But if you have no Windows, you'll have to just experiment.
-
@scottalanmiller Oh ok. I'll just install it. I found someone who has it running in Wine. I'll give that a shot. It does look really nice. Thanks again, I owe you a beer.
-
Had not considered running it in Wine, that's a great idea. Citrix wants to get it ported to Linux but there is something holding them back.
-
@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.
