Abstract
The subject matter of this specification can be implemented in, among other things, a method including receiving, by a hypervisor of a host computer system, an entropy request from a guest operating system running on the host computer system. The method further includes identifying, by the hypervisor, an entropy source. The method further includes determining, by the hypervisor, an expected entropy usage at the host computer system. The method further includes providing, in response to the request, entropy from the entropy source to the guest operating system in view of the expected entropy usage.
