[virt-tools-list] [PATCH 3/3] [NOT TO BE APPLIED] inspection: Pass log messages from libguestfs through the virt-manager logging system.

[Richard W.M. Jones]

From: "Richard W.M. Jones" <rjones at redhat.com>

This requires libguestfs >= 1.16, but that's older than the minimum
supported version of libguestfs, and even Ubuntu has libguestfs 1.18.
