Kickstart install Centos 7 using virt-install


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: ...

mkdir kick && mkdir kick

virt-install install Fedora 19 on server

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
