PVS support in XenServer 6.1 – via @_POPPELGAARD – #XenServer, #Citrix, #PVS

January 22, 2013 1 comment

Good blog post from Thomas Poppelgaard!

And this is something that many have waited for, either they upgraded and ran into the issues and had to revert back to 6.0.2… but now it’s fixed! 🙂

Citrix have released Hotfix XS61E009 & XS61E010 for XenServer 6.1 and now you are able to have Citrix Provisioning Services with XS 6.1 and use VVS.
I have been waiting for this for a while.

Issues Resolved In This Hotfix XS61E009

  1. Virtual Machines (VMs) with out of date XenServer Tools, may not be flagged as “out of date” in XenCenter. This hotfix resolves this issue and enables customers to be notified in XenCenter when new XenServer Tools are available.
  2. Booting a Citrix Provisioning Services (PVS) target device using a Boot Device Manager (BDM) image can take an extended time to complete. This hotfix resolves this issue.

Issues Resolved In This Hotfix XS61E010

  1. Customers using XenServer Platinum Edition to license Citrix Provisioning Services (PVS) may find that one PVS license per VM is checked out, rather than one PVS license per XenServer host. This may lead to a shortage of PVS licenses and an inability to provision VMs. Installing this hotfix along with CTX135672 – Hotfix CPVS61016 (Version 6.1.16) – For Citrix Provisioning Services 6.1 – English resolves this issue.
  2. Attempts to shut down Microsoft Windows Vista and later VMs can cause intermittent blue screen errors, with a "STOP: 0x0000009f..." error message.
  3. Adding more than eight NICs to Microsoft Windows Vista and later VMs, using the xe CLI can lead to a blue screen error on reboot.
  4. Copying data to a Microsoft Windows 2003 VM can cause the VMs to hang and lead to a grey screen error.
  5. When Dynamic Memory Control (DMC) is enabled, attempts to migrate Microsoft Windows XP and later VMs using XenMotion can cause the VMs to hang and lead to blue screen error.
  6. When the Citrix Xen Guest Agent service is running, Cut and Paste will not work between a XenDesktop virtual desktop and the endpoint device.
  7. Microsoft Windows XP and later VMs may hang during the boot process and may have to be forced to reboot.
  8. Attempting to install or upgrade the XenServer Tools on Microsoft Windows Vista and later VMs, which do not have access to a paravirtualized or an emulated network device can cause the installation process to hang.
  9. Manually installing the Legacy XenServer Tools without changing the device_id to 0001 can result in a "STOP: 0x0000007B..."error when rebooting a Windows VM. After installing this hotfix, customers will not be able to manually install the Legacy XenServer Tools by running xenlegacy.exe

My Post-Synergy View – Update 2 #CitrixSynergy #Citrix #CitrixSummit #XenApp #XenDesktop #NetScaler #Sanbolic

October 23, 2012 Leave a comment

Hi again!

Ok, time to wrap up my Synergy update post series… In the previous post I started to give U my view of the takeaways from Citrix Synergy. So let’s continue! 🙂

As I wrote before I tried to structure the post using the following; each heading represents the enhancement request topic and/or the takeaway item, and then the subheading of Description and Status is showing you my personal view on the topic and its status.

NetScaler

Description:

These where the items that we had on the enhancement list before going to Synergy:

  1. Create SDX platform/architecture to run on all MPX appliances, for more info why see; NetScaler MPX vs. SDX dilemma; https://richardegenas.com/2012/10/03/netscaler-mpx-vs-sdx-dilemma/
  2. Add support for AG session policies so that ICA proxy can be turned on for specific published apps and desktops and not per session. This for situations where you might have one app or desktop that sits behind an AGEE and others don’t.
  3. The NetScaler/Access Gateway HTML/GUI pages used shall be able to be customized per AGEE/AAA Virtual Server. Today they are global pages so that specific modifications/customizations cannot be made and you have to buy an additional NetScaler unless major customizations are done and then life-cycle management becomes an issue.
  4. Change so that you can specify different Authentication policies and requirements mapped to Session policies instead of to a Virtual Server, AAA group etc. This could then provide a way so that you could offer ICA proxy mode with single auth and two-factor if you launch/select to open an SSL VPN tunnel. And then a user that has forgotten a hardtoken could still get access but only in ICA proxy mode and have all virtual channels disabled without having to have multiple accounts in the Receiver and admin doesn’t need multiple NS AGEE VS.
  5. It would be good to get the same Account Self-Service functionality that the  Single Sign-On/Password Manager service can provide and have integrated into the AGEE login page where end-users can themselves unlock their accounts and reset their passwords without involving Service Desk. And the solution for how to get the single sign-on account self service feature should be an integration part of the NetScaler AGEE console rather than manually updating the HTML pages etc.

Wow, PVS creativity at its best – but still a workaround…

October 9, 2012 1 comment

Ok, I must admit that the blog post below and the efforts put into it from a creativity point of view is great!

Martin Zugec blog post about Pimp your PVS 1 – auto patcher is really neat! I give you all the creeds Martin, great work!

But, is this a solution to the problem that the PVS product has regarding configuration and patch management? NO… U still have a lot of work to do here Citrix, I’m just glad that you have such innovative and creative people like Martin to deliver interim workarounds to a problem that according to my personal believe is a major mistake in the product design and build principles.

Still waiting for a XenDesktop suite-wide “Update Manager” that handles life-cycle management of all components of the stack. Citrix has a lot of great products and now just need to “wrap it all up” and ensure that they are ready from an ITIL/ITSM point of view.

Cheers!

HEADS UP – PVS and XenServer compatibility issues

October 5, 2012 4 comments

UPDATE!!! SEE THIS POST FOR MORE INFORMATION AND PVS SUPPORT ON XENSERVER 6.1; http://richardegenas.com/2013/01/22/pvs-support-in-xenserver-6-1-via-_poppelgaard-xenserver-citrix-pvs/ 

Ok, this is something that many may be aware of but I’m sure not all of you out there! Thanks Per Liif for the inputs to this little blog post!!

So what’s the issue? Well you can summarize it by saying that XenServer 6.1 and PVS is not compliant out of the box!

The Citrix information about this issue can be found here and basically tells you that; The standard XenServer Tools do not include support for Volume Shadow Copy Service (VSS) or Citrix Provisioning Services (PVS). For customers who wish to use VSS or PVS, the legacy XenServer Tools must be used.

What does this then mean in real life if you go ahead and use the standard XenServer tools and what errors might you be struggling with if you have this issue? Answer; you’ll see blue screens like this (xenvif.sys);

So what shall you do to prevent this, well use the steps in the support article from Citrix PRIOR to installing the legacy tools (xenlegacy.exe), otherwise you’ll end up with this blue screen (xenvbd.sys);

And of course you could argue whether Citrix could have provided a bit more heads up for everyone out there in the release notes and blog posts of XenServer 6.1. I hope that not many of you ran into this and spent to much time on it prior to finding the Citrix workaround article!
