Is it possible to boot (without actually installing it) ubuntu and run Ubuntu desktop image via PXE like a Live CD? I don't want the session to actually preserve state. Each boot should be fresh and alike. Is it possible to achieve this via PXE boot.
Also when a machine is booted via PXE, after the OS has loaded, which machine's resources does the OS consume? The client's or the PXE server's? I believe it should be latter.
You can setup a TFTP-Server and put a Ubuntu-Live Image on it, to boot it via PXE on another machine. This is a fresh Live-Disk on every reboot.
The resources of the machine on which the Live-Disk is runnig will be used. But the HDD will not be touched. The Live-Ubuntu is running on a ramdisk.
You can get the Images for an Ubuntu 12.10 amd64 here: http://de.archive.ubuntu.com/ubuntu/dists/quantal/main/installer-amd64/current/images/netboot/netboot.tar.gz
This is für Ubuntu 12.10 32 bit:

EDIT: I found an example for a TFTP-config: https://wiki.ubuntu.com/LiveCDNetboot
