[Barrelfish-users] qemu: only core 0 works

Hi 

I am trying to explore the examples code running barrelfish on QEMU but not getting very far.

e.g. should i be able to run hello world on cores other than core 0?

oncore 0 /x86_64/sbin/examples/xmpl-hello       works, but 
oncore 1 /x86_64/sbin/examples/xmpl-hello       crashes

Thanks Colin
