There is a regression in bochsbios 2.4.2 that prevents gPXE from detecting PCI network devices. I hope this email saves you time if you find that suddenly virtual machines cannot find network devices to boot from.
How to know if you are affected: 1. You get "No more network devices" when running gPXE in QEMU/KVM. 2. Your bochsbios version is 2.4.2. The problem: A change in bochsbios results in the carry flag not being propagated to indicate success/failure from PCI BIOS. Since the PCI BIOS is broken and gPXE relies on it to enumerate PCI devices, no network devices will be found. Workarounds: 1. Change "#define PCIAPI_PCBIOS" to "#define PCIAPI_DIRECT" in gpxe/src/config/defaults/pcbios.h. Rebuild gPXE. OR 2. Use bochsbios 2.4.1 (or from bochsbios CVS once this is fixed).
