i am using community edition u4. VBR is running on 2019 std, Hyper-V server is free 2016 core edition without beeing member in AD (workgroup mode).
While i can backup vm with guest quiescence with no problem, i am getting error on all vms during test in guest processing tab with application aware processing enabled. I havent tried to backup with this settings due to the error during test.
Code: Select all

when i run on hyper-v: Get-VM | ft Name, IntegrationServicesVersion
i get version 0.0
But integration services are already included in Server OS since a long time. On VM IntegrationServicesVersion is 10.0.17763
