Horizon Cloud on Azure – Unable to contact App Volumes Manager. Virtualization is disabled

Issue:

You may see an error like below after deploying/Importing a VM with App Volumes agent installed.

“Message Connection Error (Manager xx.x.x.xx): Unable to contact App Volumes Manager. Virtualization is disabled”

How do I troubleshoot:

1. Login to the VM using RDP
2. Open svservice log from C:\Program files (x86) \VMware\Horizon Agents\App Volumes Agent\Agent\Logs\svservice
3. Check whether below error exists
   
   Connection Error (Manager "XX.X.X.X"):
Unable to contact App Volumes Manager. Virtualization is disabled."

   Here XX.X.X.X is POD Load Balancer IP
   
   It means from the VM we can’t reach the POD’s hence it’s failing
   
4. Now do the below steps to confirm the reachability
   
   telnet to POD Load balancer IP on port 443 & 3443 and see if it works
   
   telnet XX.X.X.X 443
   telnet XX.X.X.X 3443
   
   From PowerShell also we can test the connectivity like below
   
   
   
5. If the ports are not reachable, check the NSG rules and allow the communication
6. Also, Check if Smart Nodes Subnet is allowed for Active directory authentication through NTLM & TLS 1.2
