Doc Type:	Bug Fix
Doc Text:	Cause: Hosted engine vm devices were stored in an internal cache that was not updated when the vm was imported. Consequence: The devices were not imported since no change in the cache was detected. Fix: Keep internal cache only for devices of vms that exist in the db. Result: The devices are imported correctly without need to restart.

Description Jenny Tokar 2017-02-20 15:05:35 UTC

Description of problem:
After the engine imports the hosted engine vm it should import the vm devices. 
But that doesn't happen until the engine is restarted. 

How reproducible:
100%

Steps to Reproduce:
1. Deploy hosted engine
2. Add a storage domain and wait for the vm to be imported

Actual results:
The vm devices are not imported. 

Expected results:
After the vm is imported its devices are imported and appear in the engine ui and db. 

Additional info:
1. The devices are imported after engine restart. 
2. Hosted engine vm has some devices that are imported as part of the vm import and not as part of monitoring. Those devices are imported as expected.

Moving to 4.1.2, as it missed 4.1.1. Perhaps it can make it to 4.1.1-1.

Ack from me, we want it in a async.

Comment 3 Nikolai Sednev 2017-03-27 15:17:06 UTC

Can you describe in more details about devices that are expected to be shown?
Where are VM devices should be displayed in UI and what devices not being shown?
