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.
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.
Download the VMware Integrated OpenStack 4.1 patch and pre-patch from the product download page. The patch and pre-patch are delivered as DEB files.
Verify that your environment meets the requirements for VMware Integrated OpenStack 4.1. See VMware Integrated OpenStack System Requirements.
Verify that the network ports required for VMware Integrated OpenStack 4.1 are open. See Required Network Ports.

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.
