Hi OVM x86 (Linux) has pretty decent I/O performance, just make sure use raw disks in the VM guests in production, in development or testing if you dont need top I/O performance you can use storage repository based on OCFS2. I am not sure about OVM Sparc (LDOMs) but it should have something similar. I will check and see if I can find anything. Thanks -- LSC -- //www.freelists.org/webpage/oracle-l
