I think that I have been able to make some progress on my attempts to get virtualbox started up underSculpt by following the directions:

Now I get what appears as a crash when I tell it to add the component.

I found it a bit easier to use Qemu (kvm) instead of VirtualBox on my Debian Host.

The Qemu (kvm) invocation on my Debian system is:

$kvm -smp 2 -cpu core2duo -machine q35 -m 10096 -drive format=raw,file=genode/build/x86_64/var/run/sculpt.img -netdev user,id=vlan0 -net nic,model=e1000,netdev=vlan0

I had to up the RAM  to about 10GB as it seemed that in an earlier attempt while viewing the Sculpt log that virtualbox needed 8GB and at least now, it does not crash out due to lack of RAM which is a small step forward.

Any ideas?

Cheers
