Hi David,

Yes, those should not be fatal.  Anyway, they are caused by two things:

 1) A second set of Avocado plugins installation with different versions
    than the Avocado installation on QEMU's tests venv

 2) The tests' venv, which is created with "--system-site-packages",
    option that is described as "Give the virtual environment access
    to the system site-packages dir."

The motivation to have "--system-site-packages" is that, if the user
had any of the "requirements.txt" depedencies installed system wide,
the venv would simply use it and skip downloads.  Maybe we should make
that an optional feature, disabled by default, so that the test's venv
is better isolated and more predictable by default.

Eduardo,

I remember we discussed #2, so your opinion is appreciated here.

Thanks,
- Cleber.
