'Help to install Virt-manager on Funtoo and Gentoo.'

Installing virt-manager

In order to user the power of virtualization under Funtoo / Gentoo, you will need to install the following packets:

Note: Some extra video driver are needed and iptables is mandatory! If under Gentoo, you will need rebuild or check if already build modules in the kernel, see QEMU documentation

 # emerge --ask virt-manager qemu xf86-video-qxl app-emulation/spice spice-gtk spice-protocol net-firewall/iptables
 # dispatch-conf
 # emerge --ask virt-manager qemu xf86-video-qxl app-emulation/spice spice-gtk spice-protocol net-firewall/iptables
  • Take a cup of coffee ^^

After the installation please add you user to kvm & libvirt group (or create it) and start libvirt daemon as follow and add it as default to start after reboot:

 # gpasswd -a USER kvm ## groupadd kvm
 # gpasswd -a USER libvirt ## groupadd libvirt
 # /etc/init.d/libvirtd start
 # rc-update add libvirtd default

Configure polkit

Then we will add some changes of the default configuration, so that your user can use virt-manager without password and without to be root:

 # mkdir -p /etc/polkit-l/localauthority/50-local.d
 # vim /etc/polkit-l/localauthority/50-local.d/org.libvirt.unix.manage.pkla
 [Allow group libvirt management permissions]
 Identity=unix-group:libvirt
 Action=org.libvirt.unix.manage
 ResultAny=yes
 ResultInactive=yes
 ResultActive=yes

Starting needed modules now and after reboot

 # modprobe kvm kvm-intel tun
 # vim /etc/conf.d/modules
 modules="kvm tun kvm-intel"

After the changes you will maybe need to reboot your computer!

 # reboot

Test your installation

Now you should ready to go, just try to start virt-manager and see if ask you for a password or not ^^

 $ virt-manager
