This session we are going to go over and deploy is using an ISO and kickstart install. This is different than a PXE install and does not require a PXE nor TFTP setup. In this example everything we are accessing is over NFS mounts but could very well have been local.
Install using kickstart file over NFS
# virt-install --name rh7 --memory 10240 --vcpus=1 --disk path=/virtual/disks/centos8-2.qcow2,size=20 --os-variant rhel7.0 --network default --location /kickstart/data/ks/rh7 --initrd-inject /kickstart/data/ks/rh7/rh7-nfs-ks.cfg --extra-args="ks=file:/rh7-nfs-ks.cfg console=tty0 console=ttyS0,115200n8" --nographics
