<p dir="ltr">That is really interesting - and worrying. So many websites are run as virtual machines (perhaps even a majority) - does that mean that their SSL keys may be seeded with the same data?</p>

I just faces the problem the regeneration of SSL parameters took ages.....<br>
On virtual machines the randomness is low. Since all hardware is virtual<br>
there is no real source for the random number generator of the kernel.<br>
Install the rng-tools and add (Debian/Ubuntu) in /etc/default/rng-tools:<br>
HRNGDEVICE=/dev/urandom<br>
and restart the rng-tools.<br>
Creating keys goes now really fast. It is speeding up it even on real<br>
hardware if there is no hardware random numbers generator.<br>
