Hotfix XS60E015 for XenServer 6.0

Issues Resolved In This Hotfix

This hotfix resolves the following issues:

  1. Creating a Virtual Machine (VM) or a Virtual Disk Image (VDI) may fail due to lack of space in the NetApp storage array. This is due to an issue in Integrated StorageLink (iSL) when using NetApp storage arrays, which incorrectly configures volumes for thin provisioning.
  2. Creating a VM or a VDI on an iSL NetApp storage array may consume more than 140% of additional space on the storage array.
  3. Attempts to re-attach the VDIs from the legacy StorageLink, after upgrading to XenServer 6.0, may display incorrect storage volume information in XenCenter.
  4. VM Snapshots created on an iSL NetApp Storage Repository (SR) are deleted if a single snapshot is removed from the snapshot tree.
  5. Creating an SR on an iSL Dell EqualLogic storage array will fail, if using Dell EqualLogic Array Firmware version greater than 5.1.1.
  6. Snapshots created on an iSL NetApp storage array inflate the underlying volume and will eventually fill up the aggregate space.
  7. Changing the IP address of a NetApp storage array when attempting to re-attach the iSL SR with a NetApp storage array, may result in an iSL SR crash.

NOTE: In addition, this hotfix also includes several bug fixes.

Installing the Hotfix

IMPORTANT: Customers MUST install Hotfix XS60E001 – For XenServer 6.0 before attempting to apply this hotfix.

Customers should use either XenCenter or the XenServer Command Line Interface (CLI) to install this update. Once the update has installed, the server must be restarted for it to take effect. As with any software update, please back up your data before applying this hotfix. Citrix recommends updating all hosts within a pool sequentially. Upgrading of hosts should be scheduled to minimize the amount of time the pool runs in a “mixed state” where some hosts have been upgraded and some have not. Running a mixed pool of updated and non-updated hosts for general operation is not supported.


  • The attachment to this article is a zip file.
  • To minimise hotfix application time, specifically to avoid host reboot and VM migrations while applying this hotfix, customers should follow the instructions for installing the update using the XenServer CLI. Continue reading “Hotfix XS60E015 for XenServer 6.0”

Vulnerability in Citrix XenApp could result in denial of service

Severity: Low

Description of Problem

A vulnerability has been identified in Citrix XenApp that, when triggered, could result in a denial of service.

This vulnerability is present in all versions of Citrix XenApp, formerly known as Presentation Server, up to and including version 6.5.

Mitigating Factors

In order to trigger this vulnerability, an attacker would need to be able to directly access the XenApp server. When deployed according to established best practice, the XenApp server would not be directly exposed and an Internet-based attacker would not be able to trigger this vulnerability.

What Customers Should Do

A hotfix has been released to address this issue. Citrix recommends that affected customers install this hotfix, which can be downloaded from the following locations:

Hotfix 3 installation guide (step-by-step)

As you could read in this post Citrix has released a patch/update for Provisioning Services version 6.1. This step-by-step guide helps you through the upgrade / installation process of this hotfix.

In contrast to the previous Hotfix (CPVS61E001) you don’t have to manually uninstall the Provisioning Services server and console before installing this fix. The Citrix developers have listened to the messages out of the field that this wasn’t a good update.

A footnote to this update is that if you don’t have HA / failover enabled or configured it’s best to patch the server within a maintenance window. Your PVS server will have to reboot.


These installation packages contains the complete Console and Server install and can be used in place of Hotfix CPVS61E003,

  • The user must have administrative rights to the Provisioning Services server.
  • The SCVMM Administrator Console must be installed alongside the Citrix Provisioning services Console when SCVMM virtual machine deployment is to be used.
  • The SCVMM Console must be the same version as the SCVMM server. This is the same requirement as XenDesktop Desktop Studio.
  • WinRM configurations are no longer required when using SCVMM.
