The VMs you create in your VMware Integrated OpenStack deployment appear in your vCenter inventory. Many restrictions apply to how you manage and work with OpenStack VMs.
In most cases, you must manage such VMs in the OpenStack dashboard or CLI rather than in the vSphere Web Client.

vCenter Features Not Supported in the OpenStack API
Direct parity does not exist between OpenStack features and vSphere features. The OpenStack API does not support the following vCenter features.
Adding a host to a cluster
OpenStack cannot add a host to a cluster in vSphere.
Putting a host into maintenance mode
You place a host in maintenance mode to service it, for example, to install more memory. A host enters or leaves maintenance mode only as the result of a user request. No such function exists in OpenStack. See the vSphere documentation for instructions about entering and exiting maintenance mode.
Resource Pools
A resource pool in vSphere is a logical abstraction for flexible management of resources, such as CPU and memory. OpenStack has no equivalent to a resource pool.
vSphere snapshots
vCenter supports OpenStack snapshots, but vSphere snapshots are distinct and are not supported in the OpenStack API.
