Hey Folks,
I'm having an issue with app Vols and hope someone else has seen something similar and can help out.
Environment
- ESXi 6.5
- App Volumes 2.14
- VMware Horizon 7.5 (Instant Clones)
- VMware UEM 9.4
- Windows 10 Enterprise Build 1709
When we have writable volumes enabled, we're seeing excessive login times upwards of 2 minutes, and get worse with subsequent logins.
First issue is that reviewing the svservices.log, it appears the enabling of the Windows Firewall by the App Vol agent takes an excessive amount of time. If I run the command from an elevated CMD prompt (within the VM after it has loaded), it takes close to 50 seconds to run, but runs successfully.
This is an example of the firewall launch and completion times
[2018-09-21 22:09:27.158 UTC] [svservice:P1600:T1328] Successfully launched: C:\WINDOWS\system32\cmd.exe /c del /q /f "C:\Program Files (x86)\CloudVolumes\Agent\Logs\cvfirewall.cfg" 2>NUL && netsh advfirewall export "C:\Program Files (x86)\CloudVolumes\Agent\Logs\cvfirewall.cfg" && netsh advfirewall import "C:\Program Files (x86)\CloudVolumes\Agent\Logs\cvfirewall.cfg" (wait -1 ms)
[2018-09-21 22:10:54.641 UTC] [svservice:P1600:T1328] ExitCode 0. Finished waiting for "C:\WINDOWS\system32\cmd.exe /c del /q /f "C:\Program Files (x86)\CloudVolumes\Agent\Logs\cvfirewall.cfg" 2>NUL && netsh advfirewall export "C:\Program Files (x86)\CloudVolumes\Agent\Logs\cvfirewall.cfg" && netsh advfirewall import "C:\Program Files (x86)\CloudVolumes\Agent\Logs\cvfirewall.cfg"" (WaitStatus 0)
The second issue I have found that if I delete the writable, and recreate it, the login time decreases dramatically. Subsequent logins after the creation are better, but then they get increasingly worse. It's only until I delete the writable again that things get better.
Has anyone seen anything like this? I had opened a call with VMware support, but they havent been able to solve the problem. Any help you can provide would be much appreciated!
