Hi Jaffar!

I have successfully installed a 2 node RAC 11g system on paravirtualised Oracle Enterprise Linux 5. It's a test system for myself and RAC on 11g but so far I'm blown away by how "fast" it feels. All Xen-based systems use a bare-metal hypervisor compared to, say VMWare Server and Workstation which require an existing OS in the first place.

Setting up the virtual machines is really easy using virt-install, the only caveat is that I had to set my domU gateway to the dom0 IP address or it wouldn't pick up my NFS share. I export this from dom0 with the contents of the DVD for a NFS install of the guest OS.

You can of course also use one of the Oracle supplied disk images from OTN but that's only half the fun.

Oh, I almost forgot - if you don't want to play with the internals of Xen networking, the easiest way to get the public and private NICs is to have 2 physical NICs on your VM Server. You then define your vif as in: vif = [ 'mac=00:16:3e:09:c4:fe, bridge=xenbr0', 'mac=00:16:3e:09:c4:ee, bridge=xenbr1' ] in your domU config file. During the guest OS installation anaconda will detect 2 network cards which are bridged to your VM Server's NICs.

In coming few days we are going to have test/development RAC databases on Oracle VM. I would really like to share my expereince once the deployment is done. Meantime, It would really interesting to know the pros and cons of using Oracle VM.
