PVS 6.1 full of bugs or myths

Hi,

We recently tried PVS 6.1 and found lot of bugs in the product. Just googled for the same and found that many users were facing the same issue. Citrix released a hotfix but that will be like a full installation kit where we need to uninstall your PVS server and reinstall it with the dump inside the hotfix. Sounds like wierd.right? It would be better if they made the hotfix as PVS 6.2 rather than providing a hotfix of more that 700MB.

Hope they will resolve the issues soon in the product.

Advantages and new features of xenapp compare to presentation server

Even though the core architecture remains the same for both xenapp and presentation server they had introduced some new concepts and feature in xenapp.

1.      Moved many configuration items from citrix advanced configuration tab to citrix policies and stream lined it like Microsoft GPO.

2.      Added many HDX policies to support multimedia

3.      Introduced VM hosted application which works with xendesktop

4.      Added windows 7 user experience to published desktops

5.      Added worker group concept

6.      Increased security features linked with Microsoft UAC & Microsoft RDS

7.      Added VM provisioning feature via provisioning server

SSL Error 37

Error Message: SSL Error 37: The proxy could not connect to ;10; (STA server);(sid) port 1494”
Cause: This problems seems to occur only when the XenApp server and ICA Client are using different DNS servers
Resolution: Enabling XML Service DNS address resolution allows a XenApp server to return the Fully Qualified Domain Name (FQDN) to ICA Clients using the Citrix XML Service

best practices in deploying xenapp or xendesktop

1. Reboot schedule for XenApp servers
2. When to dedicate the XenApp Zone Data Collector roles
3. Implications of provisioned XenApp servers on License server redundancy
4. Whether pooled desktops should be rebooted at logoff
5. What components should be backed up
6. Hotfix deployment policy
7. Recommended XenServer pool size when using MCS / PVS
8. Using processor and memory overcommit
9. When the ‘Optimize for XenApp’ setting should be used in XenServer
10. Whether Provisioning Services should be scaled Up/Out

VMs are getting blue dump

VMs are getting blue dump

Hi All,

It has been observed that VMs which are provisioned from PVS 5.6 is going to blue dump state and this is mainly happening for win7 VMs. If you call citrix support they will say you to add additional 8GB of HDD for capturing the dump to find out which component is causing the blue dump. But guys there is a basic check list before calling the support. I can prove that the below check list has solved my issue....

Is there any new hardware device attached to your VM recently.
Any patches or hotfix has been applied to your VM?
Large Send Offload is disabled or not if you are using a xenhypervisor and your ethernet is a citrix PV Ethernet...This need to be checked under the Advanced configuration settings of your PV adapter....

Hope this will fix your issue....guys trust me it is working in many infras after doing the above change...

VDI not available error

1. Determine the UUID of the Storage Repository and the VDI that's exhibiting the issue
2. Run xe vdi-forget uuid=<vdi_uuid>
3. Run xe vdi-scan sr-uuid=&lt;sr_uuid>;
4. Check in XenCenter (or run xe vdi-list sr-uuid=&lt;sr_uuid>;) and you should see the VDI sitting there. Fill in the info you had before in the Properties.
5. Reattach the VDI to your VM of choice and try starting it up.
