Hey,

error/description as upstream bug :
https://github.com/virt-manager/virt-manager/issues/253
couldn't connect to any vm (qemu+ssh). gui only shows "connecting to
graphical console" but never really opening console.
also not sure when this happened, probably some time in the last few
weeks (probably related to qemu upgrade on 14/11?).
installing python3-tqdm package (as suggested upstream) solves issue, so
maybe this package should be added as a dependency.

thanks,
d.
