[pve-devel] [PATCH 0/5] fix #2264: add virtio-rng device

[Stefan Reiter]

Add the ability to provice entropy to QEMU guests via an emulated hardware RNG.

First patch in pve-manager is independent. Rest depends on new qemu-server for
the API, I left 'onlineHelp' as a FIXME to avoid the dependecy to pve-docs.

I looked closely at how Linux and QEMU handle entropy/randomness to make sure
it's fine to allow /dev/urandom by default, and I'm quite certain that it poses
no issue at all (point in case: the kernel developers themselves are talking
about making /dev/random behave like /dev/urandom after the system has booted
[0], which we can always assume to be the case for VMs). I included more
rational in the qemu-server commit message.

The benefit of this is of course that we don't have to worry about host entropy
starvation nearly as much. It's still documented and the user is warned if they
choose /dev/random in the GUI though.
