Can you share the command line you used, host arch, host OS and so on?

Sure thing !

Here goes nothing : (AIX is already installed on the AIX-ROOT.IMG1.RAW file - the fact that it is raw was just a performance test.. but same thing with qcow2).

It is booting just fine if I comment out the g_assert() statement and rebuild or go single processor.

(I'm hiding the S/N because it is an actual machine - another test)

PS : The system has been brought up to SP2 - but same symptoms.

PPS : netdev xpq01nic01 is a predefined TAP device connected to an OpenVswitch bridge.
