Depending on whether you use a new enough host and guest kernel, you can even try plan9 9p filesystem passthrough. Or you can use qemu MTP MTP filesystem passthrough (which has the bonus of being supported out-of-the-box for Windows guests): https://lists.gnu.org/archive/html/qemu-devel/2014-04/msg03319.html https://en.wikipedia.org/wiki/Media_Transfer_Protocol although I'm not sure if libvirt needs to be taught to expose that better. > 2. perform some operation on that file > 3. get the result of that operation. How would you get a bare-metal machine to perform an operation on a file it just downloads? If you would ssh in to a bare-metal machine, then ssh into your guest. Otherwise, you'll have to submit patches to the qemu list to enhance the guest agent to do what you want before libvirt can even consider adding things to automate yet another way of doing it. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
