error: exceptions.OSError ... VM test restarting too fast

Hello all,

I set up a Xen 3.0/NetBSD 4.0 system with a NetBSD 4.0 release and automatically-retrieved packages and received the errors below.

As the system has 4GB of RAM, 3320M in reality, This post may shed some light on the situation:

Can mem=3092M be added to menu.lst? If so where? (xen line or netbsd line?)

Else, does this appear to be a different issue entirely?
