XenConvert – P2V Conversions
What is it?
Feature of XenServer 5
Stand-alone Wizard Interface
Enables the conversion of a physical server or desktop workload into a virtual machine (VM)
What formats does it support?
Conversion to a XenServer ready VM (XVA) or to a Microsoft Virtual Hard Drive VM (VHD)
XenServer
Citrix XenConvert allows you to convert a server or desktop workload from a single physical disk on a physical machine to a virtualized instance in either the Microsoft Virtual Hard Disk (VHD) format, Citrix Xen Virtual Appliance (XVA) format, or a XenServer virtual machine.
Converting to a XenServer VM produces an intermediate XVA containing a bootable XenServer VM and automatically imports it into a XenServer.
Converting to an XVA produces an offline package of a bootable XenServer VM ready to manually import into a XenServer.
Converting to a VHD produces a VHD compatible with Provisioning Server 5.0 if the target device software included with Provisioning Server 5.0 was installed beforehand.

11. Power of Paravirtualization is key to performance
Allows the kernel and I/O paths to know it’s being virtualized
Cooperation provides best performance
Utilizes hardware-assisted virtualization
Fully supports Intel VT and AMD-V enabled processors
Hardware-assist allows high performance without emulation
Community Support
The older generation virtualization solutions use emulation to trick an operating system into thinking it is running on its own piece of hardware. This “hardware” is actually a large software system that emulates an entire PC.
Paravirtualization – The Xen engine uses a technique called paravirtualization. It allows the virtual machine to understand it is being virtualized and co-operate with the system to ensure the very best performance. Xen pioneered para-virtualization on the x86 platform. It is actually a technique that was used with mainframes in the 60-70’s to allow multiple operating systems to run on a mainframe with high levels of performance.
Hardware Virtualization – Xen was designed from the ground up to leverage hardware virtualization assist technologies delivered by both Intel and AMD in CPUs since last summer. Early on Intel Research was involved with the Xen project. Knowing that this hardware assist technology was coming down the line the Xen layer was designed to be very thin and easily take advantage of both current virtualization assist technologies and the slate of newer technologies being delivered in the chips in the coming years.
XenSource and the OS industry have chosen the combination of paravirtualization and hardware virtualization assist as the future of virtualization on x86. The next generation Windows Server “Longhorn” will contain a mix of Para virtualization and hardware virtualization assist.
Toll Booth Graphic – Can be used to illustrate that cars on the right hand side (paravirtualized guests) run faster because they don’t need to be checked through by a “Toll booth operator”

21. Business Continuity Automated Resource Pool Patching
From time to time, Citrix release hotfixes for XenServer. XenCenter allows you to automate the task of patching your server while ensuring application availability is not impacted.
XenCenter will automatically evacuate VMs from each XenServer and apply a hotfix to it.
It will then move to the next XenServer and do the same until the whole pool is up to date.
Servers are returned to production when finished.
Servers can also be evacuated for planned maintenance by switching them to “Maintenance Mode” 21

22. Business Continuity High Availability: Unplanned downtime
VM’s on failed physical servers can be restarted on other servers in the pool

28. Reducing XenApp Server Count

Reducing XenApp Server Count
Solution: Virtualize the server with XenServer 3-4x more users per server
Before – 100 users
After – 300+ users
So what XenServer can do is allow you to run multiple instances of 32-bit XenApp on one server. So you can deploy servers with 16 GB RAM, and scale up to 3-4 times the number of users per server, and use that processor capacity more effectively.
So today, you might have servers with 4 GB RAM and two processors supporting 100 users or less. With new hardware and XenServer, you can run 4 XenApp virtual machines and scale up to 300 users or more per physical server. Each XenApp virtual machine would be allocated 25% of the memory and processor capacity of the physical server, or about 4 GB RAM and 2 Virtual CPU’s each.

This is a typical situation many of you are in today. You have a rack of XenApp servers, perhaps coming up to the point where they need to be refreshed. You likely group your XenApp servers into “application silos” such as the example here where there are 6 SAP servers, 6 CRM servers, and 8 Microsoft Office servers. This is a “best practice” for XenApp because it eases change management and capacity planning.

It would be a best practice to add an additional server to enable some of the great capabilities of XenSErver, including High Availability and XenMotion. So you can see that we’ve placed a “swing server” in the farm for this. The swing server allows you to do two things.

XenServer can also simplify image management. For a siloed XenApp farm where we have several identical workloads, we can reduce the number of images by using the unique XenServer provisioning features. Provisioning allows you to stream the system image to each VM during boot, so you can reduce the number of images that need to be managed, patched, and rolled-back in case some sort of issue occurs following an application or OS update. So when you want to upgrade SAP, you apply that upgrade to the XenServer “virtual disk” or “vDisk” only, and then the XenApp VM’s get updated with a simple reboot. And if someone bad happens with an upgrade, you can easily roll back all servers to the known good version with just a reboot.
So you can clearly see how XenServer offers great new agility and management benefits for XenApp that can make your life as a XenApp administrator much easier, and increase availability for your end users.
To summarize we’ve reduced the number of moving parts significantly from 20 servers and 20 images to just 6 servers and 3 images.
Before: Managing 20 servers and 20 images
After: Managing 6 servers and 3 images

32. Test Results & Methodology (Physical Server)
XenApp on Physical Servers x4
Physical Servers
- Old server: Dell PowerEdge 2650 (Dual 2.6 Ghz)
- New Server Proliant DL360 G5 (Dual 3.0 Ghz)
Each with 4 GB RAM
XenApp on XenServer x1 (4 VM’s)
In Citrix test labs we compared the performance of both “old” physical servers and “new” physical servers to XenServer. The test results show that 1 XenServer running 4 XenApp VM’s performs very well compared to 4 “new” separate physical servers, and far better than 4 “old” separate physical servers.
How the test was conducted: to measure performance, we ran a “user experience test script” while we had various user counts running against the server. So we simulated the various user load levels using our EdgeSight for Load Testing tool, and then checked performance at each level using the user experience test script. The user experience script measures the completion of a set of tasks in Microsoft Office.
XenServer with 4 VM’s (Proliant DL380 G5)

Some of you may have tried virtualizing XenApp, Presentation Server, or MetaFrame in the past with somewhat mixed results. In particular, customers have reported poor performance and scalability of XenApp with other sever virutalization solutions.
One of XenServer’s advantages vs. the competition is how well it performs, especially for high-performance workloads. As you might expect, we have focused a lot of energy on being able to run XenApp on XenServer with the best possible performance.
In our test labs and even with several of our customers, we’ve shown that using XenServer can allow XenApp to support at least 30-40% more users per server than if using competitive alternatives.
This slide shows an example of some benchmarking we performed of XenApp on XenServer vs. 2 competitors, which we will call Brand X and Brand Y. While we cannot explicitly name them for legal reasons. We tested the performance and scalability of XenApp on physical hardware vs. virtual servers. So on the left, we ran one instance of XenApp on a server with 4 GB RAM and dual 3.0 Ghz processors. On the right, we virtualized the server and installed 4 instances of 32-bit XenApp into virtual machines. Each XenApp virtual machine was assigned 2 Virtual CPU’s.

34. Net Benefits: XenApp on XenServer
Server Count Reduction
Up to 75% fewer servers
60% power reduction
Enhanced Agility
Easier provisioning & change management
Increased Availability
No-downtime server maintenance
Auto-restart VM High Availability
So, to summarize. Using XenServer, you can deliver significant benefits for your XenApp environment. These include server count and power reduction, especially if you are using 32-bit XenApp…enhanced agility in terms of provisioning and change management simplification….and increased availability via the no-downtime server host maintenance and automatic restart High Availability.
