Instant clones issues - Resync of VM has failed

[Najtsob]

I have fresh setup of Horizon 7.3.2 and I have created first test instant clones pool but something doesn't work as it should.

The desktops were provisioned without issues and I could login, but after logout I got following error.

Also I have noticed this in vCenter

It seems like I got too many clones and replicas for just a single instant clone ?

Running into the same issue. 7.3.2. We are checking ESXi updates now (on 6.0) to see if maybe we are behind on an important update.

After updating to 6.0U3e we are still seeing the same behavior. Any resync operation, either from logoff or from image push causes this issue.

Clean version of Win 10 1709.

To close the loop on this, we found the issue.

This problem only occurred with dedicated instant clones (floating pools worked fine). It was because we didn't have distributed switches setup, which it turns out is a requirement for dedicated instant clone pools. So, our fault for not thoroughly reading the documentation on this newer feature of instant clones. You also need to ensure you are using static port binding with fixed port allocation.

Instant-Clone Desktop Pools

As a best practice, configure distributed virtual switches in the vSphere environment. It is mandatory to configure distributed virtual switches in the vSphere environment for dedicated instant clones.

In the connection server logs you will find the following entries
