charset="utf-8" From: David Woodhouse As we finalised the spec, we spotted that vmgenid actually says that the _HID is supposed to be hypervisor-specific. Although in the 13 years since the original vmgenid doc was published, nobody seems to have cared about using _HID to distinguish between implementations on different hypervisors, and we only ever use the _CID. For consistency, match the _CID of "VMCLOCK" too.
