Windows Entropy Source

Hello all,

I believe I am hitting a problem on one of our Windows 2003 KVM guests were it is running out of Entropy and causing SSL issues. I see that there is a module called virtio-rng which I believe passes the HW entropy source through to the guest but does this work on Windows as-well ? If it doesn’t any ideas on how I can increase the amount of entropy being generated on a headless system ?

Thank you in advance.
