I think that "check_if_path_managed" is used also in the case of a
remote connection so os.path.exists is not correct as it checks for a
local file.

I have tried several times by using a similar command line as in the bug
report but I wasn't able to reproduce the problem here (both
virt-install-1.0.1-3.fc20.noarch and upstream version), what arguments
did you feed to virt-install to get this failure?

Thanks,
