Hello Everyone,
We have recently engaged a 3rd party vendor that specializes in VDI deployment to do a health check on our environment. The number 1 issue that we are seeing is pretty high number of Customization Timeouts when publishing a pool. All those machines get eventually successfully created however this is not what we would expect. Also, once the pool is published the customization timeouts appear to be gone and machines get created properly however it takes roughly 5 minutes per one Instant Clone to be created to fulfill pool requirement ( 1 minute and 30 seconds provisioning and roughly 3 minutes customization step). I'm fully aware of VMFS 6 problems with snapshot so we moved all components, images and pools to VMFS5. We are using Horizon 7.6 and Windows 10 LTSC 1809.
The vendor is suggesting that it might be possibly due to VMware OSOT being too aggressive in disabling stuff but they cannot pinpoint to what it could be. I logged in to my master image and was hoping to simply revert any optimization done however there is nothing available in history. We are using version b1100 of the tool. I don't really feel like creating new image from scratch but if there is no other option then I can.
Did anybody encounter this type of an issue? Any possible solutions are very welcome.
