The create target for PXE or network booting an OpenBSD install. It sets the boot order to:

1. hard disk
2. network

Also new is defining the MAC address of the network interface. For QEMU this has to start with 52:54:00.

create  :
        virt-install \
        --prompt \
        --connect=qemu:///system \
        --name="${DOMAIN}" \
        --ram=2048 \
        --vcpus=2 \
        --description 'OpenBSD virt-install with serial' \
        --os-type=unix \
        --os-variant=openbsd4 \
        --boot hd,network \
        --disk path=${IMAGEFILE},size=4,bus=virtio \
        --disk path=${IMAGEDIR}/${DOMAIN}_ports,size=8,bus=virtio \
        --network bridge=br0,mac=52:54:00:aa:aa:01,model=virtio \
        --graphics vnc \
        --serial dev,path=/dev/ttyS0 \
        ${DEBUG}

In order to PXE boot and to give this VM a fixed IP address I used this entry in /etc/dhcpd.conf:

        host pxe-client {
                hardware ethernet  52:54:00:aa:aa:01 ;
                fixed-address 192.168.222.230;
                filename "pxeboot";
                next-server 192.168.222.20;
        }
