| 0. Prepare installation image. If you're going to install Windows, prepare the [https://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers Virtio driver] image too.
| |
| {{tip|You can also find the [https://aur.archlinux.org/packages/virtio-win virtio-win] package in AUR. The image is located in '''/var/lib/libvirt/images''', which is the default [https://libvirt.org/storage.html#StorageBackendDir directory pool] of qemu:///system}}

| |
| 1. Launch menu Virtual Machine Manager. It should already have a [https://libvirt.org/drvlxc.html LXC] connection. You can disconnect and remove it if you don't use LXC.
| |
| <br clear="all" />
| |
| 2. Go to File, choose Add Connection and choose hypervisor QEMU/KVM, or QEMU/KVM user session if you don't want '''system'''-level virtual machines. Click on connect.
| |
| <br clear="all" />
| |
| 3. You need directory pools to store the disk images of virtual machines or the ISO file of CD/DVD. Double click qemu/kvm, go on storage and add by clicking + the path to the folder where you have the iso and the folder where create the virtual machine.
| |
| <br clear="all" />
| |
| {{tip|My advice: use a different partition than the root. In case you need to reinstall your operating system you don't lose the VM that already ready-to-start.}}
| |
| 4. Click on create a new virtual machine: select '''Local install media (ISO image or CDROM)''', and select the installation ISO image and OS type (if not detected).
| |
| <br clear="all" />
| |
| 5. How many CPU assign and how much memory? (check the recommended requirements of O.S. that you are installing)
| |
| <br clear="all" />
| |
| 6. Create the file system of the virtual machine by selecting '''Select or create custom storage''' and click '''Manage...'''. Under your desired directory pool, create the volume of the virtual machine (default in qcow2 format). How many GB? Check the recommended requirements O.S. you install.
| |
| <br clear="all" />
| |
| 7.Assign a name to the machine and flag '''customize configuration before install'''. You have access to the screen with all the hardware that will be virtualized, do a check if there is all that is needed to initialize and launch the installer.
| |
| <br clear="all" />
| |
| 8. In ''Overview'', change the firmware to UEFI for future-proof capacity.
| |
| <br clear="all" />
| |
| 9. Change the type of SATA Disk 1 (the disk image of the creating virtual machine) to ''virtio'' for better performance. Change discard mode to ''unmap'', and then apply the change. You should notice the device name would change from SATA Disk 1 to VirtIO Disk 1.
| |
| {{warning| If you're installing Windows, make sure to create a new SATA CDROM device and select the '''virtio-win''' image as the media, so that the Windows Installer can load the driver to recognize the disk. The virtio storage driver should be located at somewhere like ''E:\viostor\w10\amd64''}}
| |
| 10. Set the NIC type to virtio too for better network performance.
| |
| {{note| If you're installing Windows, once the system if ready, make sure to install all the virtio drivers so that your virtIO network can work normally}}
| |
| 11. Add TPM chip, select '''TIS''' model through '''Emulated device''' backend.
| |
| <br clear="all" />
| |
| 12. Add a watchdog to reboot the guest when it hangs. Leave the settings as default.
| |
| <br clear="all" />
| |
| 13. And a hardware RNG, to get entropy from the host.
| |
| <br clear="all" />
| |
| 14. Click on the top to start installation.
