QEMU option ROM

Building the ROM image

Check which network adapter is configured for the VM.

Here are the adapters supported by QEMU 0.11.0 [from a QEMU on Fedora 12 (i686) installation]:

QEMU NIC 'model' PCI Vendor ID PCI Device ID Mfr Name Device Name Notes
rtl8139 10ECh 8139h Realtek RTL8139C+ Fast Ethernet Adapter Default in QEMU v0.11.0
ne2k_pci 10ECh 8029h Realtek RTL-8029(AS) Default in prior versions?
i82551 8086h 1209h Intel 82551ER/IT Fast Ethernet
i82557b 8086h 1229h Intel 82557 10/100Mbps Ethernet
i82559er 8086h 1209h Intel 82559ER Fast Ethernet
pcnet 1022h 2000h AMD AM79C970 Ethernet Adapter
e1000 8086h 100Eh Intel 82540EM Gigabit Ethernet Ctrlr


Build the appropriate ROM image:

cd gpxe/src
make bin/10ec8029.rom  # for ns8390 10ec:8029

Running QEMU

The -option-rom command-line option tells QEMU to use the gPXE ROM:

qemu -option-rom /path/to/10ec8029.rom /dev/null

This example runs a default VM with no disks and allows you to press Ctrl+B to enter gPXE.
