Guys, I'm having another problem here. After installing the OS from the CD, when I boot from the HDD to finish the installation, the guest automatically closes after a short time. Sometimes I have managed to pass through the country selection (image bellow) and even got to configure my Apple ID. Although, even if a do nothing and just wait for a little, the guest dies eventually.
Someone has experienced something like that or know how to solve it?
[edit]
Found a workaround to this problem, I ran the following command and replace the gnu-netcat for the openbsd-netcat and everything worked smoothly.
sudo pacman -S virt-manager qemu vde2 ebtables dnsmasq bridge-utils openbsd-netcat
