[libvirt] Sharing file between host and guest

[Yushu Yao]

Hi All,

    Question not very related to libvirt but I think most of the real VM
experts are in this list.

    What is the best and fastest way to share files between guest and host?
Something like the share folders-hgfs in vmware might work, but is there a
way that works on all hypervisors?

    Network based file sharing (NFS/Samba) are limited by the speed of the
virtual network interfaces. Maybe one can do it through USB?

    Thanks a lot!
