You install the VMware Integrated OpenStack 4.1 patch and pre-patch by using the viopatch utility.

The pre-patch contains an update to the viopatch utility. You must install the pre-patch before installing the patch.

Important:

The viopatch uninstall action is deprecated and cannot be used to revert to the previous version. The snapshots created in this process are therefore necessary for reversion. Do not remove these snapshots until all validation tasks have been completed and you are certain that you will not need to revert to the previous version.

Prerequisites

Procedure

  1. In the vSphere Web Client, take a snapshot of the OpenStack Management Server virtual machine.
  2. Log in to the OpenStack Management Server and take a snapshot.
    sudo viopatch snapshot take
    Note:

    This command stops OpenStack services. Services will be started again when the patch is installed.

  3. Transfer the patch and pre-patch files to the OpenStack Management Server virtual machine.
  4. Add and install the pre-patch file.
    sudo viopatch add -l path/vio-pre-patch-4.1_4.1.0.7538136_all.deb
    sudo viopatch install -p vio-pre-patch-4.1 -v 4.1.0.7538136

    You can run the sudo viopatch list command at any time to display all added patches and the corresponding version.

  5. Add and install the VMware Integrated OpenStack 4.1 patch file.
    sudo viopatch add -l path/vio-patch-4.1_4.1.0.7538136_all.deb
    sudo viopatch install -p vio-patch-4.1 -v 4.1.0.7538136

What to do next

After you have validated that the patched version is operating correctly, you can run sudo viopatch snapshot remove to delete the snapshot. This action is destructive and cannot be reversed. You cannot roll back after deleting the snapshot.

If you need to roll back to the previous version, see Roll Back a VMware Integrated OpenStack Patch.
