Description of problem: I built a disk image in my home directory using virt-builder, then tried to import it into libvirt (as non-root). It fails with: Starting install... ERROR internal error: process exited while connecting to monitor: qemu-system-x86_64: -chardev socket,id=charchannel0,path=/home/rjones/.config/libvirt/qemu/lib/channel/target/nested.org.qemu.guest_agent.0,server,nowait: Failed to bind socket: No such file or directory chardev: opening backend "socket" failed Note that ~/.config/libvirt/qemu/lib/channel/target does not exist.

qemu version is: qemu-kvm-1.6.2-4.fc20.x86_64
Libvirt should be generating that path and creating it for us

A few releases back libvirt was updated to create the socket directory if needed, so this should no longer be an issue
