Alan,
Yes. I do mean z/VM V4R3 guest Lans with virtual OSA Express (QDIO mode).

Chong, I'm going to go out on a limb here and assume that by "VQDIO" you
mean z/VM V4R3 guest LANs with virtual OSA Express (QDIO mode).
To Phil: The amount of time to clone is highly dependent (naturally) on
the DASD subsystem. Different technologies can and do yield drastically
different times. So, asking "what's the fastest" is different than
"what's the fastest Chong achieved using his evironment and techniques".
