Vmware Horizon 7.7 Windows 10 slow boot

[NaderHussein]

I recently installed Horizon 7.7

VMware ESXi, 6.7.0, 10302608

VMFS 5

Master Image Windows 10 1089

When I reboot Master Image it takes 35sec Min but when I restart the Linked clone Image it takes 4 Min.

What are your CPU, Memory, & Video Memory settings?

[vJoeG]

Is your master image joined to the domain? What other Horizon agents are in use, UEM, App Volumes?

[NaderHussein]

Master Images not joined to a domain and no other agents installed

[vJoeG]

Ok, thanks for that information. In the master image, you can go into services and make sure the VMware Logon Monitor service is set to Automatic so that it's running when all Linked Clones are online.

Then you can go to the https://<your horizon admin URL>/newadmin console and search for the logged in Linked Clone sessions. From there you should get details of what took the time during the logon.

Here is an example from my lab. You can see the segments and that GPO load was the largest at almost 8 seconds. I have been with clients where GPO was upwards of 3-4 minutes.

Hi JoeG,

Can this be done with Instant Clones also? I'm new to the Horizon/View world.

[vJoeG]

Yes, you can do Instant clones as well.

The screenshot of my login times was from an instant clone pool.

[NaderHussein]

to make it clear my problem is not with the user logon

My problem is with the windows start it take time to boot

[vJoeG]

Ah my apologies, I went down a whole different path based on user Login times vs boot times.

Still with these machines being on the domain vs not domain joined there could be something out there in your AD that is trying to start/take place that the master is not having to contend with.

Joe, How did you get the Graph?

[NaderHussein]

I am more confused. The problem is not realated to GPO. The weird thing if I do a storage migration for this linked clone machine and then storage migration back to it original location it will boot with 40 seconds. The question what storge migration change

Can you tell us more about the storage where the parent, linked clones and replicas are stored?

If you storage vMotion a linked clone I believe it converts it to a full clone. This could be a disk performance issue.

[NaderHussein]

My storage is EMC Unity All Flash with EMC Vplex

If it is a disk performance issue why the linked clone slow to boot and the parent master image fast and both are in the same datastore.

[vJoeG]

Sorry for the delay. The graph is at the bottom of the screen when you look at a VDI session from the Helpdesk tool.

https://vdi.yourdomain.com/newadmin then in the search field look for computer names or user names and you will see the running sessions and pick one to review.
