Just out of curiosity, what is your use case for qemu on the target? IIRC for Yann is was just a let's-see-if-it-can-be-done hack, that's why he never pushed it anymore. I can imagine borderline buildroot uses which have lxr or docker on the target, but full-fledged qemu? > libvirt is a fairly > standard autotools package, and shouldn't require much work, although I > did notice ./configure checked for some host qemu binaries. > > You can see Yann's work on libvirt and target-qemu here: > https://gitorious.org/buildroot/buildroot/source/e09cf6e8d412cfd6163358fc7f58c83f44cc0a38:package/libvirt > > https://gitorious.org/buildroot/buildroot/source/14ac053363188981cf7fb78b589a9e27fb464483:package/qemu > > > and my inexperienced, hackjob work over here, updates the packages to > their latest versions and removes unneeded depends: > https://github.com/md-5/Multiplicity/tree/master/package > > libvirt requires the following depends to work: > > host-pkgconf lvm2 libnl libxml2 yajl > > In order for the configure script to detect yajl properly, it needs a > (e)glibc toolchain.

We don't really have a way for accepting donations, but what we could use is: - more autobuilder instances; - sponsoring for the buildroot developer meeting.
