Virt-manager

Installing virt-manager in Mocaccino Desktop

Setup

Install virt-manager using Luet:

1

$ sudo luet install apps/virt-manager

edit /etc/libvirt/libvirtd.conf and uncomment these lines:

unix_sock_group = "libvirt"

unix_sock_ro_perms = "0777"

unix_sock_rw_perms = "0770"

Add your user to the libvirt group

1

$ sudo usermod -aG libvirt $USER

Add your user to the kvm group

1

$ sudo usermod -aG kvm $USER

Enable and start the libvirtd systemd service

1

$ sudo systemctl enable libvirtd

1

$ sudo systemctl start libvirtd

Networking

By default libvirt comes with no network configured by default.

You can check that by running:

1
2
3
4

$ sudo virsh net-list --all

Name                 State      Autostart     Persistent
----------------------------------------------------------

Create the default network by copy-pasting the following lines into a file called default.xml

 1
 2
 3
 4
 5

<network>
  <name>default</name>
  <uuid>9a05da11-e96b-47f3-8253-a3a482e445f5</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:0a:cd:21'/>
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254'/>
    </dhcp>
  </ip>
</network>

Now add it:

1

$ sudo virsh net-define --file default.xml

To start it, run:

1

$ sudo virsh net-start default

Start it permanently by default:

1

$ sudo virsh net-autostart --network default
