Oracle on Virtual Machines

Does Oracle support running the Oracle databases on VMs using SAN? Oracle also has something called Oracle VM. How does it different from Vmware solutions?.

Also, Looking to move the hardware from HP PA RISC architecture to x86 using Linux. What is the equivalent of 4 Dual Core PA8900 processeors compared to the HP Machines especially DL-G Series.

Any one has any experience of running production and development on same VM host; Assuming enough hardware resources in place any pros/cons of sharing the prod and dev on the same VM host?

Thanks in Advance.
Raja.
