The smart approach would be to let VirtualBox decide which one to use. The idea is that since emulation "wastes" a lot of computational time doing those translations, a paravirtualization setup will let the guest VM have special access to certain aspects of the physical hardware. 0 or later. Uses of paravirtualization . default selects the appropriate interface based on the guest OS type when starting the VM. 37 and VMware products in favor. Professor Robert McMillen shows you Paravirtualization in VirtualBox 6The term used "paravirtualization interface" is original and nowhere precisely describes whether the interface faces the Host (to accept the hypervisor provided by the OS) or the Guest, which would require Virtualbox to itself have the hypervisor code bits normally provided by the Host OS. In 2005, VMware proposed a transparent paravirtualization interface, the Virtual Machine Interface (VMI), as a standardized communication mechanism between the guest operating system and the hypervisor. Paravirtualization techniques expose a software interface to the virtual machine that is slightly modified from the host and, as a consequence, guests need to be modified. This approach helps the Intel TDX-architecture prevent the VMM from accessing any TD runtime state. Click on “Settings“. Leave it enabled. . 3. Additionally, reports the TSC and APIC frequency. 1. 7: Requires ESXi 6.
