I was trying to setup virt-manager following space invaders setup guide. I got to the part when you navigate to /etc/libvirt/ and change the ip to 0.0.0.0. I did that, saved and restarted and now my VM's wont start and libvirt wont start either.    I tried to copy the libvirt- folder to libvirt, then rebooted and the directory is empty again.   Any suggestions?
