Right now it is throwing NPEs > ------------------------------------------------------------------------------------------------------------ > > Key: CLOUDSTACK-6831 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6831 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Management Server > Affects Versions: 4.4.0 > Environment: HyperV > Reporter: Abhinav Roy > Assignee: Rajesh Battala > Fix For: 4.4.0 > > > Steps : > ================ > 1. Deploy a advanced zone hyperv setup. > 2. Create a VM v1. > 3. Create a VM snapshot on v1 > Expected behavior : > ================ > Since VM snapshot is not supported in 4.4.0 for HyperV, the operation should > fail gracefully with appropriate error message. >
