Installing the Cumulative Update

Customers should use either XenCenter or the XenServer Command Line Interface (CLI) to apply this cumulative update. When the installation is complete, see the Post-update tasks in the table Information About this Cumulative Update for information about any post-update tasks you should perform for the update to take effect. As with any software update, back up your data before applying this update. 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 are upgraded and some are 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 the cumulative update update package only. Click the following link to download the source code for any modified open source components XS71ECU1-sources.iso. The source code is not necessary for cumulative update installation: it is provided to fulfill licensing obligations.

Installing the Cumulative Update by using XenCenter

Before installing this cumulative update, we recommend that you update your version of XenCenter to the latest available version for XenServer 7.1 CU 1.

Choose an Installation Mechanism

There are three mechanisms to install a cumulative update:

  1. Automated Updates
  2. Download update from Citrix
  3. Select update or Supplemental pack from disk

The Automated Updates feature is available for XenServer Enterprise Edition customers, or to those who have access to XenServer through their XenApp/XenDesktop entitlement. For information about installing a cumulative update using the Automated Updates feature, see the section Applying Automated Updates in the XenServer 7.1 Cumulative Update 1 Installation Guide.

For information about installing a cumulative update using the Download update from Citrix option, see the section Applying an Update to a Pool in the XenServer 7.1 Cumulative Update 1 Installation Guide.

The following section contains instructions on option (3) installing a cumulative update that you have downloaded to disk:

  1. Download the cumulative update to a known location on a computer that has XenCenter installed.
  2. Unzip the cumulative update zip file and extract the .iso file
  3. In XenCenter, on the Tools menu, select Install Update. This displays the Install Update wizard.
  4. Read the information displayed on the Before You Start page and click Next to start the wizard.
  5. Click Browse to locate the iso file, select XS71ECU1.iso and then click Open.
  6. Click Next.
  7. Select the pool or hosts you wish to apply the cumulative update to, and then click Next.
  8. The Install Update wizard performs a number of update prechecks, including the space available on the hosts, to ensure that the pool is in a valid configuration state. The wizard also checks whether the hosts need to be rebooted after the update is applied and displays the result.
  9. In addition, the Install Update wizard checks whether a live patch (this is an Enterprise Edition feature) is available for the cumulative update and if the live patch can be successfully applied to the hosts. For more information, see Live Patching in XenServer in XenServer 7.1 Installation Guide.

    Follow the on-screen recommendations to resolve any update prechecks that have failed. If you want XenCenter to automatically resolve all failed prechecks, click Resolve All. When the prechecks have been resolved, click Next.

  10. Choose the Update Mode. Review the information displayed on the screen and select an appropriate mode. If the update contains a live patch that can be successfully applied to the hosts, it displays No action required on the Tasks to be performed screen.
  11. Note: If you click Cancel at this stage, the Install Update wizard reverts the changes and removes the update file from the host.

  12. Click Install update to proceed with the installation. The Install Update wizard shows the progress of the update, displaying the major operations that XenCenter performs while updating each host in the pool.
  13. When the update is applied, click Finish to close the wizard.
  14. If you chose to carry out the post-update tasks, do so now.

Installing the Cumulative Update by using the xe Command Line Interface

  1. Download the cumulative update file to a known location.
  2. Extract the .iso file from the zip.
  3. Upload the .iso file to the Pool Master by entering the following commands:

    (Where -s is the Pool Master’s IP address or DNS name.)

    xe -s <server> -u <username> -pw <password> update-upload file-name=<filename>XS71ECU1.iso

    XenServer assigns the update file a UUID which this command prints. Note the UUID.

    5eea06f3-4990-497d-af7a-d0bba6f9f96a

  4. Apply the update to all hosts in the pool, specifying the UUID of the update:

    xe update-pool-apply uuid=<UUID_of_file>

    Alternatively, if you want to update and restart hosts in a rolling manner, you can apply the update file to an individual host by running the following:

    xe upload-apply host-uuid=<UUID_of_host> uuid=<UUID_of_file>

  5. Verify that the update was applied by using the update-list command.

    xe update-list -s <server> -u root -pw <password> name-label=XS71ECU1

    If the update is successful, the hosts field contains the UUIDs of the hosts to which this cumulative update was successfully applied. This should be a complete list of all hosts in the pool.

  6. If the cumulative update is applied successfully, carry out any specified post-update task on each host, starting with the master.

7023547: How to run GDB to debug a process in SMG

Step 2: Shutdown the module to be tested

This step is crucial to save the headache of dealing with modules trying to automatically reload.

If possible, shut down the program either with the modules UI page, or by sending a kill command to the module from a terminal window. If the kill command is used, it MUST NOT be used with the -9 switch, as this will not allow the module to stay down.

If shutting down the module is not possible, typically due to a crash/restart loop, disable the server setting for ‘Module auto-recovery’ under the Manage Servers UI page. With this setting disabled, the program will not come back up by itself. It is important to remember to re-enable this option when the back trace has been obtained.

Step 3: Ensure gdb is installed

To get the debug information, gdb is required, but it not installed by default.

Type ‘gdb –help’ at the terminal prompt to check that it is installed.

If the help page is not displayed, install gdb by typing ‘apt install gdb’.

Step 4: Run the module in debug mode

Using the startup command determined in step 1, we can now prepare to start the application. Using the examples from step 1, and assuming the module we are investigating is gwvsmtp, enter the following commands, noting the additional switch that has been added to the end of the line:

cd /opt/gwava/assets/bin/linux/x64

gdb --args /opt/gwava/assets/bin/linux/x64/gwvsmtp "/root=/opt/gwava/" /ServerId=1 /ModuleId=1 /ConsoleLog

After typing these commands you should be placed into the gdb program at a (gdb) prompt which is ready to run the application. Type ‘r’ to start the program.

Step 5: Watch and wait

Now that the program is running, it is simply a matter of waiting for the crash to occur. The /ConsoleLog switch that was included on the command line will be echoing to the terminal display. This is the same log information that is stored in the application logs. By emitting it during the debug session, we are able to capture the end of the log along with the debug information which saves on the effort of matching log files to the information we are after.

Leave the program running until it stops. This will be evident when the log stops scrolling and you are given a prompt to type at.

Step 6: Obtain the backtrace

Once the program fails, type ‘bt’ at the prompt. This will provide a set of lines that include the information that’s useful to engineering.

Scroll back up through the information to where the logging information ends. Copy the text from approximately one screenful of logging information down to the end of the backtrace information. Pay attention to what’s in the log information and if it seems that more may be useful, copy as much as seems necessary. It is better to capture more information than less if you are unsure of what you are reading. Using the time on the log can also be a useful way to determine what might be necessary. If there are four pages of log data within the same second, chances are that’s all going to be related.

The information should look something like this:

Step 7: Clean up

To exit gdb, enter ‘q’. This will return you to the terminal prompt.

If Module auto-recovery was disabled, re-enable it on the Manage Servers page.

Restart the programs using the appropriate method for the system you are working on.

Step 8: Provide the information to engineering

Self explanatory. Add the information to the bug ticket, or via email to the engineer that requested the information.

Issues Resolved In This Hotfix

This hotfix resolves the following issues:

  • If customers upgrade a host with legacy disk partition from XenServer 6.x to XenServer 7.1 CU1, and then attempt to apply a subsequent Cumulative Update as an update, they may receive an insufficient space error. This hotfix includes a fix to reduce the calculated space required to apply the update. You must apply this hotfix to XenServer 7.1 CU1 before attempting to update to a subsequent Cumulative Update. This hotfix should not be necessary on hosts that have the new host disk partition layout introduced in XenServer 7.0.
  • When customers are attempting to use Jumbo Frames, a VM without PV drivers installed would cause the MTU to drop to 1500 as the MTU was only being set for the paravirtualised VIF device and not for the fully emulated TAP device.

This hotfix also includes the following previously released hotfixes:

Installing the Hotfix

Customers should use either XenCenter or the XenServer Command Line Interface (CLI) to apply this hotfix. As with any software update, back up your data before applying this update. 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 are upgraded and some are not. Running a mixed pool of updated and non-updated hosts for general operation is not supported.

    (Where -s is the Pool Master’s IP address or DNS name.)

    xe -s <server> -u <username> -pw <password> update-upload file-name=<filename>XS71ECU1032.iso

    XenServer assigns the update file a UUID which this command prints. Note the UUID.

    28f4de5b-9165-479e-88d2-5aafe500f507

  4. Apply the update to all hosts in the pool, specifying the UUID of the update:

    xe update-pool-apply uuid=28f4de5b-9165-479e-88d2-5aafe500f507

    Alternatively, if you need to update and restart hosts in a rolling manner, you can apply the update file to an individual host by running the following:

    xe update-apply host=<host> uuid=28f4de5b-9165-479e-88d2-5aafe500f507

  5. Verify that the update was applied by using the update-list command.

    xe update-list -s <server> -u root -pw <password> name-label=XS71ECU1032

    If the update is successful, the hosts field contains the UUIDs of the hosts to which this patch was successfully applied. This should be a complete list of all hosts in the pool.

Issues Resolved In This Hotfix

This security hotfix addresses the vulnerabilities as described in the Security Bulletin above.

This hotfix also includes the following previously released hotfixes:

Installing the Hotfix

Customers should use either XenCenter or the XenServer Command Line Interface (CLI) to apply this hotfix. As with any software update, back up your data before applying this update. 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 are upgraded and some are 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 the hotfix update package only. Click the following link to download the source code for any modified open source components XS75E006-sources.iso. The source code is not necessary for hotfix installation: it is provided to fulfill licensing obligations.

Installing the Hotfix by using XenCenter

Choose an Installation Mechanism

There are three mechanisms to install a hotfix:

  1. Automated Updates
  2. Download update from Citrix
  3. Select update or Supplemental pack from disk

The Automated Updates feature is available for XenServer Enterprise Edition customers, or to those who have access to XenServer through their XenApp/XenDesktop entitlement. For information about installing a hotfix using the Automated Updates feature, see the Applying Automated Updates in the XenServer documentation.

For information about installing a hotfix using the Download update from Citrix option, see Applying an Update to a Pool in the XenServer documentation.

The following section contains instructions on option (3) installing a hotfix that you have downloaded to disk:

  1. Download the hotfix to a known location on a computer that has XenCenter installed.
  2. Unzip the hotfix zip file and extract the .iso file
  3. In XenCenter, on the Tools menu, select Install Update. This displays the Install Update wizard.
  4. Read the information displayed on the Before You Start page and click Next to start the wizard.
  5. Click Browse to locate the iso file, select XS75E006.iso and then click Open.
  6. Click Next.
  7. Select the pool or hosts you wish to apply the hotfix to, and then click Next.
  8. The Install Update wizard performs a number of update prechecks, including the space available on the hosts, to ensure that the pool is in a valid configuration state. The wizard also checks whether the hosts need to be rebooted after the update is applied and displays the result.
  9. Follow the on-screen recommendations to resolve any update prechecks that have failed. If you want XenCenter to automatically resolve all failed prechecks, click Resolve All. When the prechecks have been resolved, click Next.

  10. Choose the Update Mode. Review the information displayed on the screen and select an appropriate mode.
  11. Note: If you click Cancel at this stage, the Install Update wizard reverts the changes and removes the update file from the host.

  12. Click Install update to proceed with the installation. The Install Update wizard shows the progress of the update, displaying the major operations that XenCenter performs while updating each host in the pool.
  13. When the update is applied, click Finish to close the wizard.
  14. If you chose to carry out the post-update tasks, do so now.

Installing the Hotfix by using the xe Command Line Interface

  1. Download the hotfix file to a known location.
  2. Extract the .iso file from the zip.
  3. Upload the .iso file to the Pool Master by entering the following commands:

    (Where -s is the Pool Master’s IP address or DNS name.)

    xe -s <server> -u <username> -pw <password> update-upload file-name=<filename>XS75E006.iso

    XenServer assigns the update file a UUID which this command prints. Note the UUID.

    76c2ec5c-c6dd-4c19-b825-f6c4391ef5a0

  4. Apply the update to all hosts in the pool, specifying the UUID of the update:

    xe update-pool-apply uuid=76c2ec5c-c6dd-4c19-b825-f6c4391ef5a0

    Alternatively, if you need to update and restart hosts in a rolling manner, you can apply the update file to an individual host by running the following:

    xe update-apply host=<host> uuid=76c2ec5c-c6dd-4c19-b825-f6c4391ef5a0

  5. Verify that the update was applied by using the update-list command.

    xe update-list -s <server> -u root -pw <password> name-label=XS75E006

    If the update is successful, the hosts field contains the UUIDs of the hosts to which this patch was successfully applied. This should be a complete list of all hosts in the pool.

  6. If the hotfix is applied successfully, restart each host in the pool, starting with the master.
