Update libvirt.rst

1. In the new version of Libvirt this --os-type is deprecated.  When we put this option we get this message "WARNING  --os-type is deprecated and does nothing. Please stop using it."
2. Some ques OS KVM console is chosen as the default boot option and when we enter the console console hangs. For this reason, we need to reboot and select Serial console.
