Do ls -lZ to see the context as well.
and VM fails, complains like this:
How about the domain's XML? What's there?
virsh # start volatile-work6 error: Failed to start domain volatile-work6 error: internal error: process exited while connecting to monitor: 2016-10-19T09:42:05.988142Z qemu-kvm: -object rng-random,id=objrng0,filename=/dev/hwrng: Could not open '/dev/hwrng': Permission denied
Did you check logs? Whether libvirt relabeled it? If there's an AVC denial? also the module itself (which owns /dev/hwrng) can check the permissions itself, so it might be needed to use some option for that module (although I believe that could be considered a bug).
which reads logical. Now - is this normal that hwrng is created with these permissions? And if yes then how to pass-through it to the VMs? How to aid VMs with hardware random numbers generator? many thanks.
