Abhinav Roy created CLOUDSTACK-4506:
---------------------------------------
Summary: In a mixed hypervisor setup, destroying a VM whose host
has been removed, throws a NPE and the ROOT volume of that VM also is not
deleted from the primary.
Key: CLOUDSTACK-4506
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4506
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Storage Controller
Affects Versions: 4.2.0
Environment: Advanced zone setup having clusters of different
hypervisor types. Ex KVM and VMWARE
Reporter: Abhinav Roy
Priority: Critical
Fix For: 4.2.1
Steps :
=========================
1. Deploy a CS 4.2 setup with KVM and VMWARE clusters having one host each.
2. Create some VMs on KVM (ex- kvm1 and kvm2)
3. Put the KVM host in maintenance mode and then remove the Host. Now kvm1 and
kvm2 are in stopped state.
4. Destroy kvm1
Observations :
========================
1. when kvm1 is destroyed it fails with the following exception
