-The daemon/ directory contains its own configure script. This is so

+In libguestfs >= 1.0.71 we don't require any vmchannel implementation,
+as long as qemu has been compiled with support for SLIRP (user mode
+networking, or "-net user"), which is almost always the case.
+
+In libguestfs >= 1.5.4 we switched again to using qemu's virtio-serial
+and removed all the other vmchannels and the SLIRP channel.

+In libguestfs >= 1.7.19 the supermin appliance is the default and only
+supported form of appliance. For more information see febootstrap
