Yes, we're using z/VM 4.2 with guest lans and hipersockets to communicate between virtual Linux images with very good results. We're suing SLES 7; make sure that you get the latest kernel patches from SuSe and the the latest qdio OCO modules from IBM. And also make sure that z/VM has the two PTFs applied that fix problems in it's implementation of virtual hipersockets; one for CP and one for TCPIP. A quick search of the IBM technical support web site will turn up which ones you need.
Good luck.
