hi all,
i'm new to netkit and unlucky, i'm unable to solve a
problem that occur when 
i try to create a new vm on a Suse 9.2.
i've tried all the two kernel (with and without skas)
without benefits.
below i quote some useful lines for understand what
the problem is, in which, 
as you will see there is a really-not-so-much
sympathetic Kernel panic.
