Proceed with further ado over there (look for pxe.* guides)
dhclient -v NIC
cd ~/ tftp PXE-SERVER-ADDRESS get pxelinux.0 ^D ls -l pxelinux.0
curl -s PXE-SERVER-ADDRESS
You can validate with VirtualBox and here’s a draft to try it out with QEMU instead
ip tuntap add tap0 mode tap brctl addif xenbr0 tap0 qemu-system-x86_64 -net nic,model=virtio,macaddr=00:00:00:00:00:01 -net tap,ifname=tap0 brctl delif xenbr0 tap0 ip tuntap del tap0 mode tap
Beware NetBSD tftp client and iPXE don’t understand each other…
