VMware Mirage – Only Download Layer

I have worked a VMware Mirage introduction as i mentioned earlier. Our project team specified very short time window for restart. It is only 30 minutes. The PCs are hosts to a cash register sofware witch is start a special way. In registry of Windows the shell was changed from explorer.exe to software’s exe.

Mirage will manage this settings that way it will restart PC without any question. NAG scrren will not ask the user about restart. Becouse of PCs connect by 3G network to Mirage, the assign process time of new bas layer is unpredictable. Other side we got a short restart time.

I figured out that we upload the changes between two base layer, and we will apply the changes a later time.

Assign Base Layer to VCD / Select “Only Download Layer”

Follow the wizard’s steps. The changes will upload to the selected CVDs, and thats all. After this process, PC will not restart automatically. We can save about 30-45 minutes.


In the Tasks menu we can see the state of process “Base Layer Download” is done. Mirage server uploaded the changes to CVD.

We can apply this changes (I call that Install process) if we select task and from right click menu choose “Apply Layers” option.


VMware Mirage will “install” the changes about 10-15 minutes, than the PC will restart automatically. It is not depens on 3G bandwith, becouse layer update process is going on PC without network usage.

vRealize Operation Manager upgrade from 6.5 to 6.6 – License issue

I think you heard about new vRealize Operation Manager release. If not check this Release Notes

It was subject of many blogs:

I admit, the new UI is brilliant, my colleagues are sharing this opinion. So U can read about new features and integration with VMware Log Insigt and Business Management.

The upgrade process same as from 6.4 to 6.5. I found a good blog which is present it step by step: https://blogs.vmware.com/management/2017/05/upgrading-to-the-new-vrealize-operations-6-5-step-by-step-david-davis.html

After upgrade process was done we realize in vRealize 🙂 something strange. When we selected a VM we seen a watermarked message in the background, as you can see in the picture below. “License is invalid”

License is invalid watermark

The solution is simple, you can go Administration / Management / Licensing page and select License Groups tab in vROPS.

Check the Licensable Usage column and if you see 0 value in Product Licensing row it will be the problem.

Check Licensable Usage

In this case select Product Licensing row and click pencil icon on top. Under vRealize Operation Manager select your license key or keys depends on your environment and click next.

Select your license key or keys

Define a membership criteria as you wish or use legacy settings. They didn’t change in our environment. If you could advice about filering I would give you, pls. contact me. Click next.

Check Preview then click Finish button.

!! Don’t forget push the refresh button on License Keys page however you can’t see the changes on License Groups page 🙂

Push the Refresh button!!!

When you did everything right on License Groups page you will see a bigger value then 0 in Licensable usege column.

I hope this short article will help for you, when you experience similar problem after your upgrade.
