I have been looking at various ways to install KVM guests and am currently using base install ISOs combined with kickstart files automatically install/configure them, but sometimes use cloning. Looking around the net, I find people installing from a PXE server instead, but never mention why.
Are there big advantages to using a PXE server rather than a local ISO image?
PXE has a bunch of benefits:
Typically you'd set this up so you only pxe-boot an installer, which then downloads the rest of the distro from either the internet or (if you do a very large amount of installs or have really shitty internet) a local mirror.
