@karuturi I understand these words: "help", "hello", "thanks", "package",
"test"
Test command usage: test [mgmt os] [hypervisor] [additional tests]
Mgmt OS options: ['centos6', 'centos7', 'ubuntu']
Hypervisor options: ['kvm-centos6', 'kvm-centos7', 'kvm-ubuntu',
'xenserver-65sp1', 'xenserver-62sp1', 'vmware-60u2', 'vmware-55u3',
'vmware-51u1', 'vmware-50u1']
Additional tests: list of comma separated tests with paths relative to the
`test/integration` directory, for example: component/test_acl_listvm.py,
component/test_volumes.py
Note: when additional tests are passed, you need to specify mgmt server os
and hypervisor or use the `matrix` command.

> [Vmware] Optimization of volume attachness to vm

> Key: CLOUDSTACK-9752
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9752
> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: VMware
> Affects Versions: 4.10.0.0
> Reporter: Nicolas Vazquez

> Fix For: 4.10.0.0

> This optimization aims to reduce volume attach slowness due to vmdk files
> search on datastore before creating the volume (search for {{.vmdk}},
> {{-flat.vmdk}} and {{-delta.vmdk}} files to delete them if they exist). This
> search is not necessary when attaching a volume in Allocated state, due to
> volume files don't exist on datastore.
> On large datastores, this search can cause volume attachness to be really
> slow, as we can see in this log lines:
