6. RedHat and SUSE announce OpenStack plans
● Top three commercial Linux distros now support
OpenStack
● All three stick with the community release functionality
● Key to long term OpenStack stability and enterprise
penetration
○ CloudStack still only runs on Ubuntu 10.04
● RedHat acknowledged Folsom as the first "enterprise
ready" OpenStack release

7. Nicira Acquisition & VMWare's involvement
"Commitment to Open vSwitch and Quantum component
of OpenStack remains unchanged."
Dan Wendlandt, Nicira: Quantum PTL
Why did VMWare join OpenStack?
● Nicira acquisition was a good opportunity
● Send OpenStack positioning signals
● Be able to "complement" OpenStack
● Competing with Citrix and CloudStack

(Quantum/Cinder)
● better instance status tracking (no more stuck in
"deleting" state, etc.)
● robust networking model:
○ create & manage nets in Horizon
○ create ip pools independently from other tenants
○ create virtual "ports" & "routers"
● convenient Glance image manipulation (via Horizon)
● block live migration (no shared storage)
● new hypervisors Excerpt: for complete presentation, go to
