Why go to the hw when vm can do it? And the use of ucb is a problem at some shops. Yes, 65k isn't enough. Marcy

One last thing you mention that " If the guests are running in the same z/VM system it makes more sense to use the VSwitch, than to use hipersockets." Why is this? Is that the benefit of the Hipersockets is lost?

If the guests are running in the same z/VM system it makes more sense to use the VSwitch, than to use hipersockets. Of course, if the Linux guests are in different LPARs then you have to use hipersockets. I defer the security aspect of the discussion to the gentleman that had his *other* hat on earlier....
