I assume you meant "even" in your reply.
If it isn't the number of CPUs, another situation I've seen cause this is Gaia trying to probe and/or interact with unknown hardware devices. In the VM settings, remove any hardware that is not absolutely necessary such as floppy drives, printers and even USB ports. If that still doesn't work, do the same thing in the BIOS of the bare metal server: disable any hardware devices that are not absolutely necessary.
