3. OpenStack Compute (Nova) Integration
§ As
of Grizzly, two drivers are available for integrating
vSphere into OpenStack:
ESX driver
(compute_driver=vmwareapi.VMwareESXDriver)
§ VC driver
(compute_driver=vmwareapi.VMwareVCDriver)
§
§ ESX
driver is unable to take advantage of advanced
capabilities (no vMotion, no DRS, no HA)
§ VC driver enables the use of vMotion, DRS, HA within
OpenStack deployments

4. OpenStack Compute (Nova) Integration:
ESX Driver
§ ESX
driver uses one nova-compute instance per ESXi
host, similar to Linux-based hypervisors
§ This nova-compute instance typically runs as a VM on
the ESXi host it is “managing”
§ Not really being developed/enhanced over time (effort
is going into VC Driver)

7. OpenStack Compute (Nova) Integration:
VC Driver
§ The
VC Driver was first introduced with Grizzly
§ Abstracts an entire cluster as a single nova-compute
instance
Details of ESXi clusters are hidden from OpenStack
§ This enables HA, DRS, vMotion, etc.
§
§ Original
Grizzly version was single-cluster driver
To scale to multiple clusters, you’d need multiple novacompute instances
§ These nova-compute instances could run as separate
VMs or as processes on the same VM

10. OpenStack Compute (Nova) Integration:
VC Driver
§ VC
Driver in Havana will introduce “multi-cluster”
operation
Allows for a single nova-compute instance to represent
multiple clusters
§ Uses multiple cluster_name parameters in nova.conf,
one for each cluster
§ Still have the option of using multiple nova-compute
instances to represent multiple clusters

14. OpenStack Block Storage (Cinder)
Integration
§ New
to Havana, not present in Grizzly
§ Allows for persistent block storage volumes to be
stored as VMDKs on VMFS datastores
§ Supports create, attach, detach, destroy operations

16. VMware OpenStack Virtual Appliance
(VOVA)
§ A
“VMware Fling”-type tool designed to help VMware
administrators experiment with vSphere+OpenStack
An all-in-one OpenStack deployment packaged as a vApp
§ Leverages vApp properties to automatically configure
OpenStack and VCDriver
