Installing virtualization software
When installing Fedora, you can install the virtualization packages by selecting *Virtualization* in the *Base Group* in the installer. See xref:f{MAJOROSVER}@fedora:install-guide:install/Installing_Using_Anaconda.adoc[Installing Using Anaconda].
For existing Fedora installations, you can install the virtualization tools via the command line using the Virtualization Package Group. To view the packages, run:
$ dnf groupinfo virtualization
Group: Virtualization
Description: These packages provide a graphical virtualization environment.
Mandatory Packages:
virt-install
Default Packages:
libvirt-daemon-config-network
libvirt-daemon-kvm
qemu-kvm
virt-manager
virt-viewer
Optional Packages:
libguestfs-tools
python3-libguestfs
virt-top
Run the following command to install the mandatory and default packages in the virtualization group:
# sudo dnf install @virtualization
Alternatively, to install the mandatory, default, and optional packages, run:
# sudo dnf group install --with-optional virtualization
After the packages install, start the `libvirtd` service:
# sudo systemctl start libvirtd
To start the service on boot, run:
# sudo systemctl enable libvirtd
To verify that the KVM kernel modules are properly loaded:
$ lsmod | grep kvm
kvm_amd 114688 0
kvm 831488 1 kvm_amd
If this command lists `kvm_intel` or `kvm_amd`, KVM is properly configured.
Networking Support
By default, libvirt will create a private network for your guests on the host machine. This private network will use a 192.168.x.x subnet and not be reachable directly from the network the host machine is on. However, virtual guests can use the host machine as a gateway and can connect out via it. If you need to provide services on your guests that are reachable via other machines on your host network you can use iptables DNAT rules to forward in specific ports, or you can set up a bridged environment.
See the https://wiki.libvirt.org/page/Networking[libvirt networking setup page] for more information on how to setup a bridged network.
