From the Architect - Neil Spellings' blog

Introduction I know this is the final part of the series, and I’m publishing it before I’ve finished parts four and five, however I was collecting all my issues and observations into a single post rather that dispersing them throughout, and as there was enough content generated from the first three blog posts, it’s probably [...]

Introduction

I’ve been wanting to take a look at Citrix XenClient type 1 hypervisor for some time, but my trusty HP Elitebook 8530W, despite having the correct Intel v-pro chipset, contained an NVidia graphics GPU so was unsuitable.

I’d been wanting a smaller, lighter laptop for a while for use when travelling (the HP Elitebook weights alot, even with SSD hard disc) so checked the XenClient HCL and narrowed down my choices to either Lenovo X1 or X220. In the end, the Lenovo X220 won out, and I grabbed a bargain in the “Black Friday” sales.

This is the first part of a series on posts on XenClient:

Part 1 – installation and management GUI (this post)

Part 2 – Creating and configuring a Windows 7 VM

Part 3 – Image management using Synchroniser

Part 4 – Findings

Installation

This was remarkably simple. Downloaded the ISO (mycitrix account required), then because the Lenovo X220 doesn’t have a CD/DVD drive, I created a bootable USB pen drive using this utility from PenDriveLinux.

Booting from the into the XenClient installer, then followed the wizard to install the software. I chose to destroy the existing factory Lenovo Windows 7 partitions. Ideally, I’d have opted for creating a multi-boot configuration, but the rather small 128Gb SSD hard disc would of become a limiting factor, so I may just swap the hard drive over if I need an alternate OS/Hypervisor.

Tour of the XenClient Receiver

Citrix call the XenClient administrator interface “Receiver for XenClient”.

Ribbon

The XenClient Receiver GUI follows the now-familiar Citrix grey look and feel, with short-cuts across the top to the various configuration options.

There is battery status indicator in the far right corner, and network icon along side it to configure both wired and WiFi networks, and the System configuration button.

On the left are Power Control drop-down, and Add VM shortcut.

Clicking on Network you get a list of the available wireless networks:

As you can see my neighbourhood is “well connected” when it comes to WiFi!

You can choose “Edit connections..” from this menu to edit/remove any existing connections you have setup:

System options

Clicking on the System options we get the main configuration settings window appear.

1. Wallpaper settings

2. Power options

Here we can configure the lid closure actions, and screen brightness.

3. Interface

The user interface options such as mouse/trackpad speeds and GUI language.

4. Login

Note the message about synchroniser credentials. Unfortunately I didn’t grab a screenshot of this before I attached my system to a Sychroniser, so there may of been some additional options here.

5. Synchroniser

This is where you “pair” the XenClient with the remote Synchroniser. Once paired, the connection status, version of the server, and userid in use are reported as shown in the screen shot.

6. Software

The version of XenClient is shown here, with an option to update. It’s interesting that the update URL is not set, even when you’ve configured a Synchroniser.

7. Hardware

Hardware details include memory usage, PCU and GPU types.

8. Networking

The various MAC addresses and chipsets of the detected networking hardware.

9. Status report

For troubleshooting, XenClient can build a status report, including screenshots of the VMs. This is wizard-based:

The file is saved to /storage/status-report/ on Dom0 so can be retrieved using SCP/SFTP.

There is also a mini web server that you can temporarily bring online to server this file via Dom0 to an external PC via port 5000:

What does this file contain? Quite a bit! Here’s the complete listing:

There are a number of useful CTRL/ALT key combinations whilst inside the Receiver console:

CTRL+Q : Reload the console

CTRL+SHIFT+T : Open a SSH terminal window

CTRL+SHIFT+H : Open a larger terminal window

CTRL+SHIFT+I : Easter Egg! (ASCII Invaders – nice!)

CTRL+ALT+r : Create a status report

CTRL+ALT+Backspace : Lock the Receiver screen

ALT+0 : Return to the Receiver (from within VM)

ALT+n : Switch to VM number n

 

So that completes the installation and tour of the XenClient Receiver.

In part two, I’ll create a Windows 7 x 64 Virtual machine, and take a look round the options we have of exposing the underlying hardware (OEM indentification strings in the BIOS and 3D graphics chipset) to the VM, and what VM management features we have via Receiver GUI.

Thanks for reading. Check back soon!

After a recent offer to use my lab to demo some of the new features in XenApp 6.5, I am now co-presenting a session with my good friend Stephane at Archy.Net (has strange accent, small beard) following my previous article on the topic.

If you’re not already attending and never been, it’s great event to share experiences and technical expertise with your peers in informal surroundings (usually some cheap hotel with poor wifi near the red light district). Of course, this autumns event is in London, so we’re near the prestigious Excel centre, Olympics 2012 park and O2 arena (formerly the Millennium dome)

Hope to see you there!
