uri_default = "qemu:///system"įor storage file permissions, open /etc/libvirt/nf and set the user and group. $ sudo chown daniel: ~ /.config/libvirt/nf $ sudo cp -rv /etc/libvirt/nf ~ /.config/libvirt/ $ sudo ln -s /home/daniel/isos /var/lib/libvirt/isosĬreate ~/.config/libvirt/nf. $ sudo ln -s /home/daniel/images /var/lib/libvirt/images
#Libvirt qemu install#
Since I have root and home on separate partitions, and I have much more storage space in home, I create an images directory there, plus an isos directory to hold Linux install images, and create symbolic links to them in /var/lib/libvirt. $ sudo apt install qemu-kvm libvirt-clients libvirt-daemon libvirt-daemon-system virtinst virt-manager bridge-utilsĭefault directory to hold VM images is /var/lib/libvirt/images. Install packages and add username (replace daniel with your own) to the kvm and libvirt groups. A result of 0 means it does not, though double-check the BIOS and see if the extensions are available and just need to be enabled. $ egrep -c '(vmx|svm)' /proc/cpuinfoĪ result of 1 or more means the CPU supports virtualization extensions. I use virt-manager and virsh as graphical and console interfaces respectively.įirst, check whether the host computer's CPU supports virtualization. Finally, libvirt provides the tools for creating and managing VMs.
QEMU (Quick EMUlator) emulates the various hardware components of a physical machine. KVM (Kernel-based Virtual Machine) is built into the Linux kernel and handles the CPU and memory details. Setup a stack of virtualization tools on a Linux host (Debian) for creating and managing virtual machines (VMs).
