[jira] [Commented] (CLOUDSTACK-10157) Wrong notification while migration

["ASF GitHub Bot (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-10157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16265725#comment-16265725 ] 

ASF GitHub Bot commented on CLOUDSTACK-10157:
---------------------------------------------

nitin-maharana opened a new pull request #2337: CLOUDSTACK-10157: Wrong notification while migration.
URL: https://github.com/apache/cloudstack/pull/2337
 
 
   Steps to Reproduce:
   ===============
   1. Create a cluster with three hosts, two of them with GPU cards NVIDIA GRID K1 and GRID K2 and one normal host.
   2. Deploy a VM with GRID K2 vGPU.
   3. Stop the VM and try starting it on a different host. (Expect it to fail as there is only one host supporting that particular vGPU type)
   4. The log shows it as failed operation, VM remains in the stopped state, yet the notification shows "Start Instance" as successful and no error message displays.
   
   Root Cause:
   =========
   Earlier, it was failing with ArrayIndexOutOfBoundsException, when the list is empty and accessing the first element.
   The error was only observed in Log, but was not showing in UI as it was not throwing any exception.
   Hence the API call was in turn successful.
   
   Solution:
   =======
   Added the empty check before sending device details.
   Which says either the required GPU device is not available or out of capacity.
