On the hypervisor

AFAIK we are not.

On the only existing hypervisor, just after booting and exiting global maintenance, causing hosted engine to start, I have

[root@ovirt01 ~]# uptime
20:34:17 up 6 min, 1 user, load average: 0.23, 0.20, 0.11

[root@ovirt01 ~]# cat /proc/sys/kernel/random/entropy_avail
3084

BTW on the self hosted engine VM:
[root@ovirt ~]# uptime
18:35:33 up 4 min, 1 user, load average: 0.06, 0.25, 0.13

[root@ovirt ~]# cat /proc/sys/kernel/random/entropy_avail
14

On the hypervisor:
[root@ovirt01 ~]# ps -ef | grep [q]emu | grep virtio-rng
[root@ovirt01 ~]#

On engine VM:
[root@ovirt ~]# ll /dev/hwrng
ls: cannot access /dev/hwrng: No such file or directory
[root@ovirt ~]#

[root@ovirt ~]# lsmod | grep virtio_rng
[root@ovirt ~]#

May I change anything so that engine VM has virtio-rng enabled?
