You are welcome :)

Tested but still does not work, here is the log for TFTP:

dnsmasq-tftp: sent /run/archiso/bootmnt/arch/boot/syslinux/gpxelinux.0

and for HTTP:

Looks like paths are incorrectly concatenated.

There are no special options for qemu, I am just using dnsmasq as TFTP
and DHCP server, and darkhttpd as HTTP server.

As said before:
# dnsmasq --port=0 \
          --enable-tftp \
          --no-daemon \
          --tftp-root=/run/archiso/bootmnt \
          --dhcp-range=192.168.0.2,192.168.0.254,86400 \
          --dhcp-boot=/arch/boot/syslinux/gpxelinux.0 \
          --dhcp-option-force=209,boot/syslinux/archiso.cfg \
          --dhcp-option-force=210,/arch/


# dnsmasq --port=0 \
          --dhcp-range=192.168.0.2,192.168.0.254,86400 \
          --dhcp-boot=http://192.168.0.218/arch/boot/syslinux/gpxelinux.0 \
          --dhcp-option-force=209,boot/syslinux/archiso.cfg \
          --dhcp-option-force=210,http://192.168.0.218/arch/
# darkhttpd /run/archiso/bootmnt


Remember that this works perfectly with 4.06 (all retrived paths looks
good, without errors).

Thanks for the feedback.
