Hello. I'm a distro maintainer and was wondering about the efficacy of entropy daemons like haveged and jitterentropyd in qemu-kvm. One of the authors of haveged [0] pointed out if the hardware cycles counter is emulated and deterministic, and thus predictible. He therefore does not recommend using HAVEGE on those systems. Is this the case with KVM's counters?
I don't know the answer. But try asking on qemu-discuss@xxxxxxxxxx or maybe KVM-related ML. Have a nice day, Martin
PS. I will be setting VM CPU settings to host-passthrough. Bonus: Also if anyone knows the answer to this question about Xen please let me know because its the other main platform we support and they don't have the luxury of virtio-rng in PVH mode. Thanks.
