It's been tested on x86_64 host with current version of qemu-dm using the RHEL-5 i386 virtual machine and by trying to setup the invalid (unsupported) model of NIC device. Also, the new constant in the net.h called the DEFAULT_NIC_MODEL has been introduced to be able to change the default NIC model easily. This variable is being used to set the default NIC model when necessary. It's been tested by running a guest with NIC model set to be "eee" which is not supported and when the guest was started I tried to issue "lspci" to list all the PCI devices and there was Realtek RTL-8239 (AS) card which is basically the ne2k_pci card (default for Xen-4.1 qemu-dm) so the old default has been preserved and it's being used as a fallback. I don't think qemu-dm and upstream QEMU should diverge again, so this patch does not sound like a good thing for Xen's ioemu codebase.
