Conrad Meyer	767991d2be	vmgenid(4): Integrate as a random(4) source ... The number is public and has no "entropy," but should be integrated quickly on VM rewind events to avoid duplicate sequences.

Conrad Meyer	ffac39deae	Add vmgenc(4) driver for ACPI VM generation counter ... The VM generation counter is a 128-bit value exposed by the BIOS via ACPI. The value changes to another unique identifier whenever a VM is duplicated. Additionally, ACPI provides notification events when such events occur. The driver decodes the pointer to the UUID, exports the value to userspace via OPAQUE sysctl blob, and forwards the ACPI notifications in the form of an EVENTHANDLER invocation as well as userspace devctl events.
