Tonight I was at a session with Wim Coekaerts
who is responsible for all Linux related stuff at Oracle.
He is also the project leader for the Oracle Virtual Server.
Wim told me that the software for the OVS will be
available for download latest Thursday this week (Nov. 15th. 2007).
I asked him whether OVS is zertified for RAC and he said
that it is not right now but it will be soon, sometime beginning next year.
