In order to build RPM packages you need to have RPM dependencies listed
in spec file installed.

I'm telling this to everyone, you usually don't want to mix distribution
packages together with projects installed directly from sources as it
usually requires additional work to make it right and to not mess up
your system with conflicting files.

You already have that, but you have to use RPM dependencies as well.

This basically works like it should as well because the uninstall
feature cannot know if the files were modified or replaced by different
project as it cannot track what's happening on the system. That's why
we have package managers.
May I ask what is your distribution and reason to use upstream package
in your distribution?
The simplest solution is to use virt-manager directly from unpacked
tarball or git repository if the distribution version is not good
enough or you want to just test a newer virt-manager.
I was about to suggest some options but once I've tried them it would
require a lot of other work to achieve it:
- Install all required dependencies using RPM, if the distribution
doesn't provide the versions you would like to use, create RPM
packages for these dependencies as well (this will probably take a
lot of time).
- Using pip to install virt-manager but when I tried it, it doesn't
work with virt-manager, most likely because we are using distutils
instead of setuptools.
- Use python virtualenv and install virt-manager into it, but it
would require to install all virt-manager python dependencies into
the virtualenv as well. To uninstall it, you can just remove the
whole virtualenv directory.
