Reason: This article is fairly new and thus not complete further expansion is highly appreciated. (Discuss in Talk:Virt-Manager)

Virt-Manager is a graphical user front end for the Libvirt library which provides virtual machine management services. Virt-manager interface makes it easy for the user to create, delete and manipulate virtual machines without going through the terminal.

Virt-manager does mainly support KVM but it can work with other hypervisors such as Xen and LXC.


Install virt-manager qemu-desktop dnsmasq iptables-nft.

Reason: Virt-Manager also supports QEMU/KVM user sessions which do not require manually starting/enabling any units. (Discuss in Talk:Virt-Manager)

To use LXC connection enable/start the libvirtd.service.

QEMU connection does not require libvirtd.service running.

You can check the unit status to make sure the service is running.


To use as a normal user without root we need to configure KVM, this will also enable the libvirt networking components.

Set the UNIX domain socket ownership to libvirt and the UNIX socket permission to read and write.

unix_sock_group = 'libvirt'
unix_sock_rw_perms = '0770'

Add your user to the libvirt user group.

Add your user to /etc/libvirt/qemu.conf. Otherwise, QEMU will give a permission denied error when trying to access local drives.

Search for user = "libvirt-qemu" or group = "libvirt-qemu", uncomment both entries and change libvirt-qemu to your user name or ID. Once edited it should look something like below.

# Some examples of valid values are:
#       user = "qemu"   # A user named "qemu"
#       user = "+0"     # Super user (uid=0)
#       user = "100"    # A user named "100" or a user with uid=100
user = "username"

# The group for QEMU processes run by the system instance. It can be
# specified in a similar way to user.
group = "username"

Upon opening Virt-Manager, it will default to the system variant (root) of the QEMU connection.

This can be changed to the user connection by going to: File > Add Connection.

Now select QEMU/KVM User session as the Hypervisor and click OK. This will now auto-connect to the user session. You can now disconnect and remove the system connection if desired.
