Yes, you can do that on a z990/z890, z9, or z10 as long as you have May 2006 or newer microcode. (This is mentioned in the OSA-Express Customer Guide and Reference, p.13.) BTW, with z/VM 5.4 you have layer 2 support for VM TCP/IP. Linux has had layer 2 for a long time. You don't need a layer 3 VSWITCH unless you have z/OS guests.
