also if you can use instant clones, the linked clone process can take some time, and in recent versions there isn't much instant clones can't do and should be available with all licenses now I believe.
I followed that.
Can't use Instant Clones. Horizon Standard + Persistent desktop.s
I think this is related to View Composer Agent. It seems to be the one hanging the boot for those minutes.
But am unable to fix it.
Did you do everything with the exception of picking the instant clone agent. The are multiple optimizations that are available. If you do that and you still have problems, I suggest opening a case with support and have them go over the logs. The log locations are here
and there is a specific composer log.
RAS guests boot in 10 seconds, so I'm sure my image and hardware is fast. Not sure if you are familiar with Parallels RAS, but it is like VMware View.
It creates linked clones from a master image, boots them and does a "quickprep", and reboots again and the guest is ready.
Same hardware, same vSphere, same image, boots in 10 seconds. Customizes in 10 seconds.
The view composer log just shows a "gap" between two entries.
I can see log entries at time = t; and then time = t + 5 minutes (for customization).
And then time = t and then time = t + 1 minute for regular boot.
But there is nothing between the two log entries.
That guide is the made by VMware and I've used it may times, which is why I suggest following it exactly. a 5 minute boot time there is a problem. The other place to look at is the composer server its self and the connection server logs. These are different products with different requirements.
This is looking like Group Policy issues. How many policies you are applying. If possible share logon monitor and UEM debug logs. It will be easy to analyse.
Also share gpresult -H file also.
So we can identify the issue exactly.
