Help to install Virt-manager on Funtoo and Gentoo
Installing virt-manager
First we need to add some information to build virt-manager and qemu correctly:
# echo "app-emulation/virt-manager gtk policykit" >> /etc/portage/package.use
# echo "app-emulation/qemu spice" >> /etc/portage/package.use
# vim /etc/portage/make.conf ## and add
QEMU_SOFTMMU_TARGETS="arm x86_64 sparc"
QEMU_USER_TARGETS="x86_64"
In order to user the power of virtualization under Funtoo / Gentoo, you will need to install the following packages:
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
