[ovirt-users] [Ovirt 4.0.6] Suggestion required for Network Throughput options

[TranceWorldLogic .]

Hi,

I am using host as Centos 7.3 and guest also centos 7.3
it have 3.10 kernel version.

But I not see virtio-rng in guest VM. Is this module come with kernel or
separately I have to install ?

Thanks,
~Rohit
