NACK, for any device listed in the XML, we should add it in the per-VM cgroups setup code.
The existing /dev/random & /dev/urandom devices are there because they are used for basic crypto libraries unrelated to the XML config.
/dev/urandom, probably. /dev/random - really? Isn't that a DoS potential for one guest to starve entropy from other guests, in spite of sVirt? I think you are right ..
The /dev/hwrng device does not fall into this scenario.
Agreed.
