When VMware Workstation/Player does an Easy Install of SUSE Linux (and most other Linuxes), it does this:
- mount a CD drive with the autoinst.iso image
- mount a floppy drive with the autoinst.flp image
For Linux, both of them contain autoinst.xml files to automate the boot process.
It has a few drawbacks including a hardcoded boot partition size and unmount problems, so if you don’t want those, follow the guidelines at How to Stop Easy Install in VMware Workstation.
