Get into your machine's BIOS, typically UEFI today, and disable TPM ! Otherwise none of the steps below will work!!īoot computer using F2 into the BIOS setup mode ( alternate keys include 'Enter' or 'Delete').Features required for Hyper-V will not be displayed’ - then it's still not disabled. The telltale test is running "systeminfo" from the command prompt and if you see ‘A hypervisor has been detected. You need to check to make sure that Hyper-V is not running. it can work as virtualization software with the help of KVM if the guest architecture is compatible with the host's and if the VT instruction is present of course.it can work as an emulator, this is the mode explained above.This requires the virtual machine and the host to be instruction compatible.Įmulation is the process of running any machine inside a running OS, there is no platform restriction, and is why QEMU can run an ARM machine on an amd64 platform. Virtualization is the process of running a complete isolated machine inside another, but with the help of the processor. QEMU works because it does not do virtualization but emulation, which is completely different and explains why QEMU is painfully slow. So your question would more aptly be: "Why don't VirtualBox and VMware Workstation work inside a Hyper-V virtual machine?" One can answer because as a VM, the Intel VT-X instruction are no longer accessible from your virtual machine, only the host has access to it.
A special one, but nonetheless a virtual machine. This means that when you enable Hyper-V, your Windows 10 "host" becomes a virtual machine. The main difference is that a level 2 hypervisor is an application running inside an existing OS, while a level 1 hypervisor is the OS itself. VirtualBox and VMware Workstation (and VMware Player) are "level 2 hypervisors." Hyper-V and VMware ESXi are "level 1 hypervisors."
