Who Should Install This Hotfix?

This is a hotfix for customers running Citrix XenServer 6.0.2.

IMPORTANT: Any issued driver disk and the Driver Development Kit (DDK) for XenServer 6.0.2 must be updated to be compatible with this hotfix. See CTX134481- Driver Disks for XenServer 6.0.2 with Hotfix XS602E007 for a list of the affected driver disks that must be updated.

Issues Resolved In This Hotfix

This hotfix resolves the following issues:

  1. Restarting XAPI in a pool consisting of a large number of VDIs can cause the pool slaves to enter maintenance mode indefinitely.
  2. Attaching an SR, containing a large number of VDIs to a pool slave, can fail.
  3. Copying multiple Virtual Disk Images (VDIs) concurrently across Storage Repositories (SRs) can cause a pool master to slow down and it may sometimes become unresponsive.
  4. An error message is triggered after a failed attempt to unplug a Virtual Block Device (VBD) connected to a mounted VDI. However, any subsequent attempts to unplug the VBD, will not trigger the expected error message, and instead a time out error message will be displayed after 1200 seconds (20 minutes).
  5. Creating a NIC bond can result in loss of network connectivity when VLANs are present when using the Linux bridge.
  6. Users can now specify the TimeStamp Counter (TSC) mode for a Virtual Machine (VM) by running the command, xe vm-param-set uuid= platform:tsc_mode=<0,1,2,3>.
  7. Constant transmission of low data rate Ethernet traffic through the netback interface can saturate a dom0 CPU.
  8. When creating an SR or a VDI, predefined XML entities, such as ??????&?????? entered in the Name and Description fields are written directly into the SR metadata. Any subsequent actions such as creating an SR or a VDI will fail with an error message, as the XML parser will fail to parse metadata which contains predefined entities.
  9. If there is a failure or a change in the number of paths to storage, attempts to create or destroy a VDI on an LVM-based SR may fail.

In addition, this hotfix also includes fixes released in CTX132823 - Hotfix XS602E001 - For XenServer 6.0.2, CTX133166 - Hotfix XS602E003 - For XenServer 6.0.2, and CTX133812 - Hotfix XS602E005 - For XenServer 6.0.2.

Installing the 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.

NOTE: The attachment to this article is a zip file. It contains both the hotfix update package, and the source code for any modified open source components. The source code is not necessary for hotfix installation: it is provided to fulfil licensing obligations.

Installing the update using XenCenter

  1. Download the update to a known location on a computer that has XenCenter installed.
  2. In XenCenter, on the Tools menu, select Install New Update. This displays the Install Update wizard.
  3. Click Next to start the Wizard.
  4. Click Add... to upload a new update.
  5. Browse to the location where you downloaded the hotfix, select it, and then click Open.
  6. From the list of updates select XS602E007.update and then click Next.
  7. Select the hosts you wish to apply the hotfix to, and then click Next.
  8. Follow the recommendations to resolve any upgrade prechecks.
  9. Click Install to start the installation.

Note: The XenCenter controlled upgrade process reboots each host sequentially starting with the Pool Master, where possible VMs will be migrated to other running hosts to avoid VM downtime. When the Pool Master is being rebooted, XenCenter will be unable to monitor the pool.

Installing the update using the off-host CLI

  1. Download the update to a known location on a computer that has the XenServer CLI or XenCenter installed.
  2. Extract the xsupdate file from the zip.
  3. If using Windows, start a Command Prompt and navigate to the XenCenter directory, for example:
  4. cd C:\Program files\Citrix\XenCenter
  5. Upload the xsupdate file to the Pool Master by entering the following commands:
    (Where hostname is the Pool Master's IP address or DNS name.)
    xe patch-upload -s <hostname> -u root -pw <password> file-name=<path_to_update_file> XS602E007.xsupdate
    XenServer assigns the update file a UUID which this command prints. Note the UUID.
    1649abf5-848b-4ce5-8657-b6e974dce37e

  6. Apply the hotfix to all hosts in the pool, specifying the UUID of the hotfix:
    xe patch-pool-apply uuid=<1649abf5-848b-4ce5-8657-b6e974dce37e>
  7. Verify that the update was applied by using the patch-list command.
    xe patch-list -s <hostname> -u root -pw <password> name-label=XS602E007
    If the update has been successful, the hosts field will contain the UUIDs of the hosts this patch was successfully applied to. This should be a complete list of all hosts in the pool.
  8. The hotfix is applied to all hosts in the pool, but it will not take effect until each host has been rebooted. For each host, migrate the VMs that you wish to keep running, and shutdown the remaining VMs before rebooting the host.
  9. To verify in XenCenter that the update has been applied correctly, select the Pool, and then click the General tab. This displays the Pool properties. In the Updates section, ensure that the update is listed as Fully applied.
