sudo qemu-img create -f qcow2 /var/lib/libvirt/images/centos7.qcow2 15G

sudo iptables -t nat -A POSTROUTING -j MASQUERADE
or
firewall-cmd --zone=external --add-masquerade --permanent
firewall-cmd --reload

This helps avoid errors like: dracut-initqueue[688]: Warning: unknown network kickstart URL: ...

virt-install install Fedora 19 on server

Leave a reply

If you love Fedora and want use it on your server, but don’t like graphical interface. Its not problem, lets download Fedora ISO image like Fedora-Live-LXDE-x86_64-19-1.iso from http://fedoraproject.org/en/get-fedora-options

virt-install –connect qemu:///system -n Fedora19 –disk path=/var/lib/libvirt/images/guest.qcow2,format=qcow2,bus=virtio,cache=none –cdrom /tmp/Fedora-Live-LXDE-x86_64-19-1.iso –video=vga –network=bridge:virbr0,model=e1000 –accelerate –noapic –keymap=en-us –ram 1024

before you should create qcow disk image:

qemu-img create -f qcow2 /var/lib/libvirt/images/guest.qcow2 10G -o preallocation=metadata

I am using bridge networking so can access Fedora using SSH. You should disable LXDE graphical interface, because I guess you don’t need it.

ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target

and reboot your Fedora guest
