libvirt users - Jun 2012 - virtio_rng in a KVM VM

Hi,

I am virtualizing with KVM via libvirt and virt-manager. To have
decent amounts of Entropy in the guest, I tried loading virtio_rng in
a running VM. Despite the module being loaded, I didn't get any log
entries, and also no /dev/hwrng.

Do I need to enable the virtualized random generator in
libvirt/virt-manager? If so, how do I do that? Is the support for this
rather recent feature already implemented in qemu-kvm 1.0, libvirt
0.9.12 and virt-manager 0.9.1?

Any hints will be appreciated.

Greetings
Marc

No host side support for this exists in QEMU/KVM yet
