Welcome to the entropyservice wiki!
and indeed any of the Alix Geode boards. Confirmed running obsd 5.[23]
dd if=/dev/random of=/tmp/randombits bs=1M count=100

this entropy shows itself to pass dieharder and rng-tests very well
Alix is an enterprise grade board and processor from PCEngines. It is very stable and highly suitable for production installations often used as a gateway router, wifi AP or vpn endpoint
cost approx £50 second hand else about £130 brand new including board, case, cf card and psu
wattage less than 5W

apparently it does have a h/w rng and it might be considered for home installtions
cost approx £80-100 including all psu, cables, sd cards etc
wattage approx 5W

step 1 : use entropyservice to supply the HOST with sufficient entropy
step 2 : virsh edit to enable virtio-rng in <devices> in your guest's xml conf
<rng model='virtio'>
<backend model='random'>/dev/random</backend>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
</rng>
step 3 : stop the VM completely and now virsh start your VM, a simple reboot of the VM wont pick up the change
step 4 : in the GUEST install rng-tools
for instance in Debian : aptitude install rng-tools
edit /etc/default/rng-tools add or edit the line ....
RNGDOPTIONS="--fill-watermark=90% --feed-interval=1 --rng-timeout=0 --random-step=256"
save and
/etc/init.d/rng-tools restart
you should now see
ps aux | grep rngd
root 1673 0.0 0.1 96516 376 ? SLsl Mar06 0:37 /usr/sbin/rngd -r /dev/hwrng --fill-watermark=90% --feed-interval=1 --rng-timeout=0 --random-step=256
step 4 : there is no step 4!
now enjoy more entropy in your Virtual Machine
