![]() We can now allocate the space for the VM: qemu-img create -f qcow2 disk.qcow 5GĪnd then we can use the disk space we have just allocated for storage by adding the argument: -drive file=disk.qcow,format=qcow2. ![]() sudo qemu-system-x86_64 -enable-kvm -cdrom ĭownloading the ISO provides for faster access at runtime. This example is just for illustration purposes - it is not generally recommended without verifying the checksums Multipass and UVTool are much better ways to get actual guests easily. You can achieve this by running the following command: While there are more user-friendly and comfortable ways, the quickest way to get started with QEMU is by directly running it from the netboot ISO. ![]() libvirt provides an abstraction from specific versions and hypervisors and encapsulates some workarounds and best practices. ![]() In that case it uses the hardware virtualisation technology to virtualise guests.Īlthough QEMU has a command line interface and a monitor to interact with running guests, they are typically only used for development purposes. However, it is more often used as a virtualiser in collaboration with KVM kernel components. QEMU is a machine emulator that can run operating systems and programs for one machine on a different machine. Multi-node configuration with Docker-Composeĭistributed Replicated Block Device (DRBD)
