How can I create/configure a VM so that it essentially simulates a diskless machine?
Furthermore, how would I configure the boot sequence of this VM so that it uses PXE booting, as listed in the steps at http://www.schnozzle.org/~coldwell/diskless/, which are as follows:
For starters, how would I "select PXE ROMs as the boot device"?
"The boot sequence is as follows
1. PXE ROMs are selected as the boot device.
2. PXE ROMs DHCP an IP address, the address of a boot server, and the name of a boot loader.
3. PXE ROMs stash the IP configuration into a known location in memory, download the boot loader (pxelinux) and start it.
pxelinux reads the IP configuration and downloads a corresponding configuration file.
4. pxelinux gets the name of the compressed Linux kernel and compressed RAM disk image from the configuration file, downloads those and starts the Linux kernel with parameters from the configuration file.
5. The Linux kernel configures its network interface from the ip= parameter possibly starting another round of DHCP in the process.
