Testing XenServer 6.2.5 beta

Thanks to this tweet, I decided to test latest build of XenServer. Let's see what we have here.

First, I don't have any physical host left to install it on bare hardware. Let's play virtception!

Step1: install Xenserver 6.2.5 in... Xenserver 6.2

No problem with that, just few clicks in XO: Go to the Add Vm page and fill forms like this:

  • Template: Other media install
  • Name: xenserver 6.25
  • RAM: 2GB
  • ISO: main.iso (name of the iso downloaded from here)
  • Create a disk of 20GB


Here is the summary:


Let's go! After the install in the console, we need to connect this XenServer to Xen Orchestra, just add it in Settings:


And now, see the result on the main page (with a VM installed on it: so a VM in a VM in XenServer):


Step 2: Explore

Now, we open a console on your new XenServer 6.2.5 beta and see this:

  • kernel 3.10.27-0.xs1.
  • Xen version 4.4.0-xs83904-d Modern kernel, latest Xen possible! Hell yeah! But... we need to go deeper.

Step 3: Profit

Current stable of XenServer doesn't support Debian testing (Jessie) in paravirt mode. Why? Because Pygrub installed lacks LZMA / XZ compression support.

Thus, do NOT dist-upgrade your Debian in Jessie in XenServer stable. Your VM will fail (can't boot). I choose to try it on this Beta version of XenServer. But, I prefer to replay things if I'm wrong, by doing a snapshot (this feature is accessible in XOA 3.3).


As you can see, a snapshot is created, and if I want, I can revert my VM to the previous state (also rename or delete):


After a Debian upgrade and a reboot, surprise! It's works!


That's great! I hope Citrix will release soon a stable version for 6.2.5. There is a lot of great things under the hood and it works out of the box with Xen Orchestra.
