What I've done now in virtual environment: 1-Install F23 server, default, no options. 2-Update, reboot 3-Install minimal X: dnf groupinstall base-x dnf install xterm xorg-x11-xbitmaps xorg-x11-fonts-ISO8859-15-75dpi xorg-x11-fonts-ISO8859-15-100dpi xorg-x11-fonts-misc dnf install xorg-x11-xdm xorg-x11-xsm xorg-x11-xkb-extras xorg-x11- xfs xorg-x11-xfs-utils xorg-x11-twm 4-Install VM environment: dnf install qemu qemu-common qemu-guest-agent qemu-img qemu-kvm qemu- kvm-tools qemu-user qemu-system-x86 dnf install libvirt virt-manager virt-install 5-Switch to graphical and the error is there: su -c virt-manager 6-Reboot and add very basic gnome: dnf install gnome-desktop3 gnome-commander gnome-abrt gnome-disk- utility gnome-menus gnome-shell gnome-shell-extension-common gnome- terminal gnome-themes-standard gnome-tweak-tool 7-reboot, switch to graphical: a) Still error in xterm: su -c virt-manager b) Surprise: the VM icon works as expected! Same result on a phisical machine with the difference that trying to switch back to multi-user freezes the box.
