https://en.wikipedia.org/wiki/Hypervisor
"The distinction between these two types is not necessarily clear. Linux's Kernel-based Virtual Machine (KVM) and FreeBSD's bhyve are kernel modules[5] that effectively convert the host operating system to a type-1 hypervisor.[6] At the same time, since Linux distributions and FreeBSD are still general-purpose operating systems, with other applications competing for VM resources, KVM and bhyve can also be categorized as type-2 hypervisors."
