Changing Fedora 19's terminal resolution

Fedora 19 defaulted to a high resolution terminal (minimal install, not a terminal app) and it wouldn't fit in my screen (KVM VM).

Change it temporarily;

yum -y install fbset
fbset -xres 1024 -yres 768 -vxres 1024 -vyres 768 -depth 24
# Short form of the command above:
fbset -g 1024 768 1024 768 24

Change it permanently;

echo "GRUB_GFXMODE=1024x768x24" >> /etc/default/grub
echo "GRUB_GFXPAYLOAD_LINUX=1024x768x24" >> /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
reboot
