# Virsh

Virtual Machine Management
|
|
|
|
## Before you Begin
|
|
|
|
1. Add yourself to the `qemu` and `libvirt` groups: `usermod -aG libvirt,qemu ducoterra`
|
|
2. Change the images ownership to qemu: `chown -R qemu:qemu /var/lib/libvirt/images`
|
|
3. Change the iso ownership to qemu: `chown -R qemu:qemu /var/lib/libvirt/iso`
|
|
4. Allow group write access to images: `chmod 770 /var/lib/libvirt/images`
|
|
5. Allow group write access to iso: `chmod 770 /var/lib/libvirt/iso`
|
|
6. Tell virsh to connect to your root system rather than your user: `export LIBVIRT_DEFAULT_URI='qemu:///system'`
|
|
|
|
## VM Details
|
|
|
|
```bash
|
|
# Show node info
|
|
virsh nodeinfo
|
|
|
|
# List OS variants
|
|
osinfo-query os
|
|
|
|
# List all current machines
|
|
virsh list --all
|
|
```
|
|
|
|
## Creating VMs
|
|
|
|
If you have [an osbuild
|
|
image](/active/software_osbuild/image_builder.md#installing) you can run
|
|
|
|
```bash
|
|
sudo systemctl start osbuild-composer.socket
|
|
composer-cli compose list
|
|
composer-cli compose image --filename /var/lib/libvirt/images/fedora-42-test.qcow2 image-uuid
|
|
```
|
|
|
|
now to have a qcow2 available during install.
|
|
|
|
```bash
|
|
# `--location /path/to/image.iso` supplies a disk installer. (Remove `--import`)
|
|
# `--import` skips the installation process.
|
|
# `--graphics spice --video qxl --channel spicevmc` installs graphics
|
|
# `--console pty,target.type=virtio` adds a console connection
|
|
# For any command, use `virt-install --arg=?` to see all available options
|
|
virt-install \
|
|
--name fedora42-test \
|
|
--description "Test VM with Fedora42" \
|
|
--cpu host-model --vcpus sockets=1,cores=8,threads=2 \
|
|
--ram=8192 \
|
|
--os-variant=fedora41 \
|
|
--import --disk path=/var/lib/libvirt/images/fedora-42-test.qcow2,bus=virtio \
|
|
--network bridge:virbr0 \
|
|
--graphics none \

|
--console pty,target.type=virtio
|
