Hello List,

I'm having trouble booting with dfly-2.2.1_REL.iso in VirtualBox 2.2.4.
It boots to the prompt asking for 7 options, but it seems, no matter
what I try (enable/disable APCI, IOAPIC, etc), I can't get it to boot
beyond that. I keep getting the error::

  Fatal trap 12: page fault while in kernel mode.

Is there a known fix/workaround for this problem? I'd really like to
play with dragonfly, but don't have access to any dedicated hardware.

Hi Louis,

Have you enabled the VT-x/AMD-V option in VirtualBox? It will only be
available in the case your processor has virtualization extensions
(Intel Core2duo/Core2quad and AMD Athlon64 x2 among others).

I haven't been able to run DFBSD in VBox without it.

Regards,
Antonio

Yes, I'm running an Intel Core2duo with VT-x/AMD-v enabled.
Are there any particular networking/drive/etc.. configs that are
required for dfly to work?  Below I have appended my dfly.xml file from
VirtualBox for reference.

It works here on a Core2Duo on Windows XP host, with only ACPI and
VT-x/AMD-V activated. Make sure that virtualization extension are
properly enabled in your BIOS (if proceeds).

I just double checked, this hardware is a Coreduo, not a Core2duo so
that may be it.  But oddly VirtualBox checks (and shades out) the
VT-x/AMD-V box.  This probably means that option isn't available to me.

Thanks anyway Antonio.

Any other suggestions?
