KVM, Hyper-V) in the VirtualBox VM settings is a guest OS dependent setting and has nothing to do with any underlying hypervisor. In paravirtualization, the guest operating system is explicitly ported before installing a virtual machine because a non-tailored guest operating system cannot run on top of a virtual machine monitor (VMM). As a result, these mechanisms must be invoked with care. Follow. Improved performance. Paravirtualization refers to the software technique, which allows virtual machines to have a software interface, instead of attempting to emulate an entire hardware environment. Para-Virtualization Full Virtualization vs. 5] Disable Hyper-V One possible cause of this problem is the Hyper-V conflict with VirtualBox. In my case, I can confirm that for all my VMs experiencing this problem, changing the Virtualbox setting "System -> Acceleration -> Paravirtualization Interface" from "Legacy" to "Default" enabled these old VMs to work again. 26.
