2.2. RHEA-2010:0240: gpxe

A new package, gPXE, is now available for Red Hat Enterprise Linux 5.5
gPXE is an open source Preboot Execution Environment (PXE) implementation and bootloader. Designed to be direct replacement for proprietary PXE ROMs, gPXE also supports additional protocols such as DNS, HTTP, iSCSI and ATA over Ethernet. gPXE is a significantly restructured update to the original Etherboot package.
Previously gPXE was available as a separate, and not officially supported, ISO image. As part of the Red Hat Enterprise Linux 5.5 update, a gPXE package containing ROMs for devices emulated by QEMU is now available as an integrated and supported Red Hat Enterprise Linux package. (BZ#512045 & BZ#545886)
Note: gPXE does not replace etherboot. Both packages, howver, write their .zrom files to the same directory -- /usr/share/pxe-boot. KVM links to whatever ROM files are present in /usr/share/pxe-boot and installing gPXE provides support for several specific PXE servers that are not supported by Etherboot.
KVM users wanting PXE server support not provided by Etherboot should install this new package.
