I've been running different tests of the latest Atlantis ILIO for Hyper-V release in my lab environment (ILIO now supports 2012R2 as well as 2008R2) when I came across an issue with Virtual Machine Manager. I'm running VMM 2012 SP1. I've recently moved from running VMM 2008R2 to 2012.
What I wanted to do was import VMs back into my library for redeployment. However when I kicked off the process I got the following error message:
A usefully cryptic message. A search on the web led to this discussion on technet.
I too tried all the steps mentioned; permissions on AD computer objects, changing the BITS port number, updating the winrm version on my 2008R2 server from v2 to v3, unblocking ports, turning off the firewalls..
I could push from the library - just not import.
Despite the message saying "winrm" it definitely felt like as permissions issue. I then looked at the library settings for my configuration.. turned out that I didn't have any credentials set for Library Management. Once I fixed that - everything uploaded as it should.
Why wasn't the error message "you don't have permission to do this?". Don't know. Its not the first time that a Microsoft error message has caused trouble by not being accurate in the detail, and I'm sure it won't be the last. The moral as always is to check all components in the chain to make sure they are configured correctly and to be aware that the error message might not be telling the full story.
It is a common question - "what books do you recommend I read to help with understanding how to deploy and manage my XenApp environment?". A number of the "official" texts deal more with the project of scoping, designing and implementing an environment, and then tend to trail off, finish before it gets to the nuts and bolts of actually maintaining, changing the environment as the project moves out into production - to support. Where it is actually important for the Citrix admin. This doesn't satiate the Citrix Admin appetite.
Packt Publishing have been putting great effort into expanding their virtual and cloud epublishing portfolio to include titles relevant to Citrix admins. Titles focused on the delivery of XenApp and XenDesktop. Esther Barthel has ably offered the plate to take on producing the ebook, Citrix XenApp 6.5 Expert Cookbook. From that you have a comprehensive menu of practical guides walking you through installation, configuration, maintenance and scripting of all components of a XenApp 6.5 infrastructure.
Too many food references? Let's continue the feast.
As I've mentioned, an issue I find with some of the over baked tomes produced for XenApp, is that there is a emphasis on what XenApp does, how it fits into your environment, the process of preparation and understanding - prior to delivery.
There is a mere entree of resources available for admins who want a full smörgåsbord of practical instruction on how to actually deliver and maintain. This is what Esther serves up in Citrix XenApp 6.5 Expert Cookbook. Topics on the menu are indeed comprehensive. You'll be able to choose from License Server config, both Web Interface and StoreFront - with useful shout outs to community options for localization. Given mobility is increasingly key, Netscaler (all be it Netscaler install is a pre-req). Vitally, management and monitoring with reference not only to Citrix tools such as EdgeSight (all be it Edgesight installation is a pre-req), Perfmon and Health monitoring; polices and load evaluation.
The eDocs guides at Citrix tend to offer a simplistic view of setup and configuration. There is very little there on on-going management which is ofthten the remit of the blogs and forums. This is where Esther's book adds value. Sections that stood out for me in Esther's book were:
Maintenance and Monitoring - which talked about hotfix management, reboot schedules and tools available - aggregating documentation and KB articles reducing the time you have to spend looking for stuff.
XenApp Troubleshooting - Esther baking in her experience as a Citrix Certified Integration Architect to give you the full flavour of troubleshooting looking at Citrix tools such as query, dsmaint, and walking through powershell scripting: a key skill for XenApp admins where you
Finally, and importantly, the resources available to Citrix Admins from the wider Citrix community. It is always more fun to eat with friends. An array of delectable references to free tools such as Carl Websters XenApp 6.5 Documentation Scripts, Dane Youngs Citrix Chained Reboot Script and Michel Stevelman's Farm Nanny to pick just three from a most excellent list.
It is difficult to pick out a bad taste. Maybe the odd change in ordering.. talk about IIS installation before WI or Storefront given the roadmap Storefront before Web Interface; XD 7.0 not being the successor to XA6.5; bit more on powershell scripting - Brandon Shell has an excellent site, and Shaun Ritchie has some useful intro scripts. But then there is the icing on the cake, Esther's community spirit in including that chapter engendering more sharing and as its an eBook - an option to update and evolve.
"what books do you recommend I read to help with understanding how to deploy and manage my XenApp environment?". I recommend this one - Esther Barthel's Citrix XenApp 6.5 Expert Cookbook. Bought it myself. Definitely not money wasted. Effective and understandable instruction on configuration and management of your XenApp 6.5 environment.
Well worth adding to your virtual book shelf.
When deploying Citrix XenDesktop and/or Citrix XenApp, many organisations utilise Citrix Provisioning Services (PVS) to not only manage the images for deployment, but to look to reduce the storage capacity requirements of their virtualised desktop and application infrastructure.
Still, it is common to find that as user load increases, user experience degrades. It is often suspected that the storage environment (typically a SAN) for the PVS environment is the bottleneck. Many of our customers speak to us in order to address a concern that their PVS delivered XenApp/ XenDesktop service isn’t delivering as expected. Our partners recommend Atlantis ILIO as part of their stack in order to simplify the architecture and contain the cost of the physical infrastructure.
What are the common questions and best practices for delivering an optimised XenApp/XenDesktop environment when using Atlantis ILIO and Citrix PVS?
Desktop virtualization projects often see a few different pain points when during deployment: sizing issues, high storage costs and scalability. However, it doesn't have to be. In this session learn the various different obstacles most organizations have to address during implementation.
