You’re probably thinking that you’re going to make a Windows VM and play some AAA games. What’s missing from the list above? The OS that stands between the hardware and the hypervisor (KVM). Virt-Manager is a GUI front-end for managing virtual machines through libvirt.libvirt is collection of software that provides a convenient way to manage virtual machines and other virtualization functionality, such as storage and network interface management.QEMU makes use of KVM to use CPU extensions for virtualization. KVM is a hypervisor built into the Linux kernel.While using the KVM/QEMU/Virt-Manager ( and libvert ) combo you’re almost running on bare metal making the experience much faster. That being said, it’s not all fun and games when it comes to VirtualBox.Įven if you only have to install VirtualBox and VirtualBox guest-aditions to start creating your VMs ( and maybe the extension pack ), VirtualBox emulates hardware to feed to the guest OS. Many OS’ are even optimized for VirtualBox. Why so many choices for the home user? Because having choices is always a good thing, and none of them are perfect. So, today we’re taking a look at how to install and use KVM/QEMU/Virt-Manager to set up your virtual machines. We talked about KVM and QEMU before, when we went over how to install macOS on Linux. Linux users also have the option of using KVM/QEMU/libvirt and a GUI client like Virt-Manager. Being VMWare, Parallels, VirtualBox or GNOME Boxes. is impossible for 64 bits VM machine:įor example if you unckeck "Hardware Acceleration", in the configuration menu of a given 64bits VM machine, the VirtualBox configurator protests, and re-enable automatically "Hardware Acceleration".Creating virtual machines is fun. VM properties -> System -> Acceleration:ĭisabling HW accel. ONLY the first one is able to run with a default configuration!!!!īut Disabling Hardware acceleration, is it possible as suggested in answer by Now Forget Qemu/KVM, and I tried to start a 64 bit VM in VirtualBox, and after a secaond 64 bit VM at the same time in VMware, or in the reverse order: Will be, PROVIDED you uncheck Intel-VT or AMD-V usage !!! While => VMware player or workstation 14.1 Is not able to make running at the same time on Linux, after KVM has locked Intel-VT or AMD-V access, and extra 64 bits Virtual Machine !!! With AMD Atlon X2 or X4, or AMD FX 8-core, or with Intel Core I5 or I7,(machines where I could make a try), => VirtualBox 5.2.10 To give some light about answer by David Baird above: If you start some usage of Qemu/KVM for a 64bits Virtual Machine, then VirtualBox at the same time CANNOT make running a 64 bits machine, because VirtualBox does REQUIRES HW acceleration for 64 bits VM. Only one can use Intel-VT or AMD-V at a moment 1 root root 1136640 Mar 30 20:20 vsock.tarįor source: module compiled at installation)ĪS SAID by roadmr (the second answer above) The others by VMware (look in : ll /lib/vmware/modules/source/ Vmw_vmci 81920 1 vmw_vsock_vmci_transportĪll the lines including kvm -> used by Qemu/KVMĪll the lines including vbox -> used by VirtualBox Vboxdrv 483328 3 vboxnetadp,vboxnetflt,vboxpci Once all of them are installed you have this : lsmod | egrep 'vm|vbox|kvm' Installing Qemu/KVM, VMware workstation and Virtualbox ON THE SAME HYPERVISOR is possible.
