[Qemu-discuss] VirtIORNG not working

[Werner, Patrick]

Hi,

we had some trouble with tomcat7 and the blocking /dev/random devices on KVM guests. So i’ve just tried to enable virtio-rng for the KVM guests like described here:
http://wiki.qemu-project.org/Features-Done/VirtIORNG

lsof /dev/random shows qemu - on the guest 

cat /sys/devices/virtual/misc/hw_random/rng_current

shows virtio.

But if i  cat /dev/hwrng nothing happens…. 

Any advice is very appreciated
