This happens when syslinux is compiled using gcc-4.7. The same code compiled using 4.6 works fine. 4.7 produces non-working pxelinux and regular ldlinux. When pxelinux.0 is run inside qemu-kvm virtual machine, i see the following: ... !PXE entry point found (we hope) at 9BE2:0456 via plan A UNDI code segment at 9BE2 len 08A8 UNDI data segment at 9C6D len 2D28 Getting cached packet 01 02 03 My IP address seems to be C0A8583C 192.168.88.60 ip=192.168.88.60:192.168.88.4:192.168.88.4:255.255.255.0 BOOTIF=01-52-54-00-12-34-56 SYSUUID=00000000-0000-0000-0000-000000000000 TFTP prefix: Trying to load: pxelinux.cfg/default ok _ And the machine stays at this place eating 100% CPU - most of the time. Sometimes qemu-kvm produces the following: KVM internal error.
