Impossible to start Virtualbox image

[mauro at freedomotic.com]

Hi,
I'm trying to test your Virtualbox image but at startup I receive the
following error

Failed to start Load/Save Random Seed
Unit systemd-random-seed.service entered failed state
piix4_smbus 0000:00:07.0: SMBus base address unitialized - upgrade BIOS or
use force_addr=0xaddr
intel_rapl: no valid rapl domains found in package 0

I'm using Virtualbox 4.3.8 on Windows 8 64 bit.

Thanks in advance
Mauro
