Added Network Security Policy support for VMs deployed via VM operator service – Security Policies on NSX-T can be created via Security Groups based on Tags. It is now possible to create NSX-T based security policy and apply it to VMs deployed through VM operator based on NSX-T tags.
Supervisor Clusters Support Kubernetes 1.22 – This release adds the support of Kubernetes 1.22 and drops the support for Kubernetes 1.19. The supported versions of Kubernetes in this release are 1.22, 1.21, and 1.20. Supervisor Clusters running on Kubernetes version 1.19 will be auto-upgraded to version 1.20 to ensure that all your Supervisor Clusters are running on the supported versions of Kubernetes.
Check before update
If you upgraded vCenter Server from a version prior to 7.0 Update 3c and your Supervisor Cluster is on Kubernetes 1.9.x, the tkg-controller-manager pods go into a CrashLoopBackOff state, rendering the guest clusters unmanageable
I’d like to point your attention to a new and useful feature which was introduced with vSphere 7 update 2. It is easily being overlooked in the abundance of new features, but it does a very good job in the prior to a vCenter update.
A requirement for the Update Planner is participation in the Customer Experience Improvement Program (CEIP).
The first sign of a new vCenter update is a notification banner at the top of vSphere Client.
Clicking on “View Updates” will take you directly to the Update Planner. This can also be found in the menu. To do this, select the vCenter in the Hosts & Clusters view and select “Updates” > vCenter Server > Update Planner in the menu bar at the top right.
All currently available updates are being displayed. In the case shown below, the vCenter is already at 7.0 Update 2, so only one possible update is listed. If several possible updates are available, the Update Planner can check the compatibility against all of them. To do this, select the radio button of the desired update (red box).
Once an update is selected, the action field “Generate Report” turns blue and shows the two possible sub-items “Interoperability” and “Pre-Update Checks“.
The Interoperability Check verifies not only the ESXi hosts but also the compatibility with other VMware products registered in vCenter.
In the old days of virtualization a vCenter used to be a nice-to-have commodity. But these times are long gone (at least from an IT point of view). In today’s datacenter many services and applications rely heavily on vCenter. Some of the most common use-cases are VDI-environments, cluster balancing mechanisms like DRS or Storage-DRS and even backup software needs vCenter.
The last one is a crucial point. It’s good to have your vCenter Server Appliance (VCSA) backed up regularly and most of you and your customers will likely do so. But think of what would happen if you’d loose your vCenter for like 10 minutes or even an hour.
