We know, thats why the default CPU for NOVA on Qemu is Core2Duo (and
nothing older) in our run tool.

Theoretically, this is sufficient for the NOVA kernel.

You are at your own. KVM caused in the past trouble and we did abandon
the idea to use it with the NOVA kernel.


Paul,

if you really really really want to get this running on this very very
very old CPU, we need to have serial output. We can't work with guesses
or any attempts to run it virtualized. On the other hand, why you want it ?

For Genode Sculpt TC we don't envision to run on such old hardware. Even
if you get it booted, it will make no fun to use with Sculpt (to few
memory, to slow CPU, not supported network card, no IOMMU support,
virtualization support is unclear etc etc...)

What about our suggested hardware [0,1] for Sculpt TC ? Refurbished
versions of the machines are not that expensive - or at least some more
_recent_ Intel machine - if you are really interested. If you just want
to give it a spin without the desire to run it on a daily basis, running
Sculpt TC in a VM should be sufficient.
