If FreeBSD runs on QEMU, and QEMU exposes part of the Viridian extensions, = the primary hypervisor should still be reported as QEMU, and hence the CPUID detection is accurate. The fact it was not like this originally is in my opinion a bug, and not a behavior we should carry moving forward. If there's a desire to use Viridian based extensions or devices on non-nati= ve HyperV, then the HyperV code should be adjusted to deal with it. It's howe= ver complicated, as it's my understanding most hypervisors that expose part of = the Viridian extensions do so with Windows guests in mind only. It's unclear whether enabling both HyperV and native hypervisor virtualization assistanc= es or devices couldn't result in failure. --=20 You are receiving this mail because: You are the assignee for the bug.=
