--------------------------------------
hi Rajani,
Do you mean vm snapshot is implemented for KVM, or only this issue is fixed?
> Cloudstack:KVM:: Snapshot stuck in Creating Status forever.
> ------------------------------------------------------------

> Key: CLOUDSTACK-6171
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6171
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Infra, Install and Setup, KVM, Management Server
> Affects Versions: 4.2.0, 4.2.1
> Environment: RHEL 6.4
> Reporter: Rohit Kumar
> Priority: Blocker
> Labels: newbie, test
> Original Estimate: 168h
> Remaining Estimate: 168h

> Hi,
> I am working on CloudStack infrastructure service to build our organization
> framework.
> For this purpose, RHEL 6.4, Cloudstack 4.2.1 and KVM are being used.
> I have been working around for long to figure out the below mentioned Issue
> but unfortunately could not.
> Issue: Snapshot gets stuck in the state "Creating" forever.
> Impact: Couldn't get the snapshot consequently and thus, the instance from
> the CloudStack's UI could not be started/Stopped.
> Please see below trace from Management Server log which I think is the reason
> behind this.
