viornd — VirtIO
entropy source
viornd* at virtio?
When the system has entropy demand, the
viornd driver, used with a compatible hypervisor
such as QEMU, KVM, or Google Compute Engine, requests entropy using the
VirtIO random number interface and feeds it into the system entropy
pool.
The viornd driver appeared in
OpenBSD 5.5.
The viornd driver was written by
Stephan Fritsch
<sf@fritsch.de> and
reworked to request entropy upon demand by Thor Lancelot
Simon
<tls@NetBSD.org>.
VirtIO appears to support at least 8 pending entropy requests, but
viornd currently supports only one pending request
at a time.
