10 things in AD that can hurt your Application and Desktop Virtualization efforts and how to fix them

One of the best sessions at BriForum 2012 came the way of Carl Webster. Lots of prep-work and material at the ready for the audience. Carl used four separate test environments for his session, Windows 2003, Windows 2008, Windows 2008 R2 and Windows 2012.

While I think Carl spends a lot of time with Citrix the content is valuable for everyone, View, XenDesktop and for PC lovers a like.

You can find a copy of his presentation at the bottom of the page. THE GOODS

#VDI Tip 70: Fixing the View Agent on Persistent Desktops without Recomposing

This is guest post from a co-worker, Brent Robin. Good find if you run into the problem.

1) Go to the vsphere vCenter where the vm is located and login to the VM via the console.

2) Login into the VM locally as administrator only.

3) Uninstall the View Agent. Reboot the VM.

4) Log back into the VM as the local Administrator and follow these directions as per this link > http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2002765

5) Disable any TP Autoconnect services associated to Thinprint.

6) Disable the antivirus scanner if applicable.

7) Install the View Agent ver that is applicable and reboot the VM.

8) Check the View Administrator console to make sure the Status shows “Available”.

9) Have user log back into their VM to ensure its stable.

It has been over a year now of blogging on ITBLOODPRESSURE.com and it’s a been lot of fun. I just started off doing VDI tips on twitter but found I could provide more value through a blog. I am happy to contribute to a wonderful community as I have been on the receiving end many times. Below are my Top 5 since the blog has been up and running. The list is based on what I like, not on how many hits I have received.

#VDI Tip 65 – Repeat After Me – Tools and then the Agent

Anytime you upgrade the VMware tools on your VDI image you need to reinstall the View agent again. The tools can replace the VGA driver and end up causing blurriness, disconnects or no connection at all. I found a nice table at the Teradici website and in a VMware KB that you can reference.

VDI-IOmark – VDI Storage Benchmarking For People With A Schedule

Translating Max IOPS into how many users you can fit onto a storage array(s) can be a pretty complicated question to ask of someone. Workloads are random between users, different blocks sizes are hitting the storage, AV is getting in the way and the list goes on and on. 20 IOPS per user is big joke in the VDI space. While 20 IOPS may represent the average, the deviation from that number can be astonishing. I encourage you watch Applied Math for VDI Design: A Statistical Approach to Designing VDI Environments. The session was presented at BriFourm last year and now is free. If you watch the video, you will see and understand what you need to be planning for.

VDI-IOmark from Evaluator Group is a tool that can tests your storage subsystem with realistic workloads. IOmeter can only give you simulated IO and not all the crazy behaviors of actual workload. VDI-IOmark uses workload replay from previous work captured from VMware RAWC implementation(View Planner). VDI-IOmark has 64 unique replays. The workloads range from 5 IOPS -20 IOPS on average but have peaks over 100. Microsoft Office(Excel, Powerpoint and Outlook), Internet Explorer, 7zip and Windows Media Player were all used to creat the replay. Boot and steady were also included in the replay. The tests are not dependent on your server platform, switching fabric or storage protocol so that’s a big thumbs up but it doesn need to run on .

The great thing about VDI-IO mark it that requires less the time to configure than building out a full environment. This is great if want to repurpose some old storage and test it our prior too or if you’re a consultant, you can do apple to apple comparisons between different vendors. Also since is each replay file contains 8 workloads test you can test your storage subsystem will less server hardware, you don’t need all the RAM it would normally take in a traditional LoginVSI or View Planner test. It’s always hard to get more money for test gear but people always want to know what the expensive box can do in the datacenter.

#VDI Tip 64: Follow the Network Checklist

Funny thing about Virtual Desktop Infrastructure, it usually relies heavily on the network. Most of my last two days has been spent troubling shooting dropped PCoIP packets, so I feel it’s timely to make sure you have your basis covered.

So here is the big tip of the day, Read and follow this check list – PCoIP Virtual Desktop Network Design Checklist

Networking isn’t my strongest skill but luckily I work with some really smart people. I think the biggest take away from the checklist is WRED.(Weighted Random Early Detection). It provides preferential traffic handling for packets with higher priority. It can selectively discard lower priority traffic when the interface begins to get congested. Try to get your PCoIP traffic prioritized just under VoIP traffic. The above document notes ” Do not configure WRED on the physical interface as it will override all other QoS policies”. Most traffic monitoring tools are not granularity enough to catch the spikes in traffic. In the land PCoIP, 1 minute intervals does not pass the test.

If you have access to your Cisco Router, you can check for drop packets by using the CEF (Cisco Express Forwarding) commands.
show cef drop
show ip cef switching statistics

You can also check for high CPU utilization. Sometimes high CPU utilization will cause buffering. Buffering = BAD

Run something different than Cisco? Please comment and leave commands for other vendors.
