    Yes, with your input, this was the fix:

Hi Mark,

Did you solve this by any chance? Looking at the debug logs it looks like the Msvm_KvpExchangeComponent is not set on the host so the heartbeat fails thus the deployment stops/hangs. This is correctly done when using a 2022 template for deployment.

xxx.local):root/virtualization/v2 WQL query select * from Msvm_KvpExchangeComponent where SystemName='80EE1416-1818-4FBE-8F33-8DC6E1E76612'"

"Message":"CarmineException [ex#3db] caught by IsGuestAgentHeartbeating Exception recieved when checking for heartbeat from vm guest

 

Regards,

Peter
