pacaur -S uml_utilities qemu virtmanager virt-manager-qt5 ebtables dnsmasq bridge-utils
Change the group= line to group="kvm".
sudo systemctl enable libvirtd
sudo systemctl start libvirtd virtlockd virtlogd
sudo virsh net-start default
sudo virsh net-autostart default
GUI is sudo virt-manager (seems as if it has to be ran as root)
I needed to edit the XML config (in virt-manager -> "Virtual Machine Details" -> "i" icon):
- CPU -> "Choose Hypervisor Default"
- Remove extra keyboard and mouse (right click, "Remove")
