'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

Creating TUN/TAP device

This allows the guest to communicate with the bridge. QEMU's default group is kvm, ensure that the correct group is given permissions to control the TAP. Enabling promiscuous mode (promisc) for the adapter might be unnecessary.

 # modprobe tun ## or reboot your computer!

Starting needed modules now and after reboot

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

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
