Virtualizing Citrix?!

Duncan Epping · Mar 18, 2008 ·

There’s been so many discussions on whether to virtualize Citrix Servers or not I can hardly keep track. But today I was pointed out to a discussion on the VMTN forum. Especially Jason Boche’s contribution to this thread is very valuable and makes sense on why you actually should virtualize your Citrix environment. Jason discovered the following:

A few of the things we’re seeing:
1. The VM is handling slighly more users with a fraction of the hardware used
2. The VM is managing application memory more efficiently which I think will allow us to get more theoretical users on a VM than on physical hardware because with 4GB of usable RAM, we always run out of memory first. I need to find out if the memory efficiency is is due to VMware’s Content-Based Page Sharing (see http://www.waldspurger.org/carl/papers/esx-mem-osdi02.pdf). My knowledge of VMware’s page sharing thus far was that pages were shared between VMs only. The memory efficiency I’m seeing when running Citrix inside a VM suggests that VMware page sharing is being used to share common memory pages inside of just a single VM of the same Citrix published application that is being run 40 times in 40 concurrent users sessions.

This is also something that’s new to me, VMware is also doing intra-VM page sharing besides inter-VM page sharing. Which indeed can be really beneficial for Server Based Computing. In the end this will enable you to virtualize more servers on the same hardware and taking advantage of those quadcore processors like no other platform does. Especially the dual-quadcore servers nowadays hardly ever get fully utilized with additional memory and VMware you can solve this inefficient usage of hardware.

Not only the usage will be more efficient but the uptime and portability will increase and with the usage of templates and for instance Thinstall it should be very easy to prep new Citrix servers in a matter of minutes. Than again with Windows Server 2008 and Thinstall small to medium companies might not even need Citrix, and I’m not even talking about the new upcoming VDI features like offline working, patch one patch many and linked cloning.

More info on ESX + Citrix can be found in this PDF that VMware released a while back. And be sure to read the topic on the VMTN forum.

SBC and VDI will definitely make a giant leap over the next months!

VDI pdf’s…

Duncan Epping · Jan 29, 2008 ·

VDI seems to be hot lately. VMware just posted 4 pdf’s which are related to VDI and/or VDM:

Using VMware VDI and vmSight for Stronger and Sustainable HIPAA and PCI Compliance


For many organizations, HIPAA and PCI compliance is no longer optional. Penalties are increasingly stiff, and the ultimate cost of non-compliance – the breach of personal data – can damage organizations in multiple ways. Compliance, and validation of compliance, is not easily achieved. It is especially difficult when computing environments are widely distributed and not all computers are centrally managed.
Virtualization technologies, including virtual desktops, offer an improved means to centralize computing, management and monitoring while still providing users local access and full functionality. For organizations seeking stronger HIPAA and PCI compliance, relying on virtual desktops for access to sensitive systems provides both cost savings and increased manageability and security. With an integrated compliance monitoring and reporting system such as the vmSight virtual network intelligence
suite, virtual desktops can be used to increase compliance and reduce data breaches while also reducing IT costs.

VMware VDM 2 Load Balancing Guide


Once appropriate server-grade hardware has been selected, load balancing become an important consideration for addressing a configuration’s scalability and fault tolerance.

In general, load-balanced configurations use multiple VDM Connection Servers installed in a primary-and-replica manner, with the first server installed as the primary and subsequent servers are installed as replicas. VDM Connection Servers provide session management and handle all incoming client requests, directing them to the appropriate virtual desktop session, and VDM Security Servers provide SSL tunneling capabilities for encrypting communication between the client devices and the VDM Connection Servers.

The configuration of a load-balanced solution largely depends on the requirements of the organization for which it is being deployed. Companies that already have a load balancing solution in place may be able to utilize it for VDI since the load generated by the VDI solution is minimal. Both hardware-based load balancing appliances and inexpensive (or free) software-based load balancing products can be considered as candidate solutions.

Windows XP Deployment Guide


VMware® Virtual Desktop Infrastructure (VDI) transforms the way customers use and manage desktop operating systems. Desktop instances can be deployed rapidly in secure data centers to facilitate high availability and disaster recovery, protect the integrity of enterprise information, and remove data from local devices that are susceptible to theft or loss. Isolating each desktop instance in its own virtual machine eliminates typical application compatibility issues and improves users’ personal computing environments.

This guide offers best practices for creating Windows XP-based templates for VMware VDI-based solutions
and for preparing the same templates for use with Virtual Desktop Manager 2.

Using the Wyse V10L and S10 Thin Clients with VDM


This technical note provides a reference for configuring Wyse V10L and S10 devices for use with VDM. VDM supports the Wyse V10L and S10 Thin Client devices, running Wyse Thin OS version 5.3.0.9 or later. For detailed information about deploying and managing Wyse thin client devices, contact Wyse directly.

Wyse Thin Client devices with versions of the Wyse Thin OS earlier than 5.3.0.9 do not support HTTPS connection to a VDM Server. You must upgrade the Wyse Thin OS to version 5.3.0.9 or later to use HTTPS.

Unlike VDM Web Access or VDM Client, Wyse thin clients connect to desktop virtual machines directly using RDP and connections do not pass through a VDM Connection Server. As a result Wyse thin clients cannot be used in DMZ deployments.

Thinstalled VirtualCenter client

Duncan Epping · Jan 25, 2008 ·

My colleague Edwin had some spare time on his hands and decided to Thinstall the VirtualCenter client. I just tested the client and it works great. Starting the client is as fast, and maybe even faster, as a normal install. Check his article on Thinstallguru.com. Let’s hope VMware will also provide a Thinstalled version soon of the client, fully supported and compatible with Wine for the Linux users. I also heard that Thinstall is busy including Wine code into the Thinstall kernel for compatibility reasons. Hope they will fix this soon.
