Hi,
We have 2 independent devices running openbmc software on each of

using SLIP protocol. Now we would like to emulate the same using qemu.
Do we have any provision to communicate 2 guest machines over a serial

When docs are explicitly requested, require Sphinx>=1.6.0. When docs are
explicitly disabled, don't bother to check for Sphinx at all. If docs
are set to "auto", attempt to locate Sphinx, but continue onward if it
wasn't located.

In the event that there's no vendored source present and no sufficient

NetBSD cannot successfully run "ensurepip" without access to the pyexpat

This is a workaround intended for Debian 10, where the debian-patched

environment.
We don't support Debian 10 as a build platform any longer, though we do
still utilize it for our build-tricore-softmmu CI test.

Several debian-based tests need the python3-venv dependency as a
consequence of Debian debundling the "ensurepip" module normally
included with Python.
As mkvenv.py stands as of this commit, Debian requires EITHER:
(A) setuptools and pip, or
(B) ensurepip

This is a teeny-tiny script that just downloads any packages we want to
vendor from PyPI and stores them in qemu.git/python/wheels/. If I'm hit

Python virtual environments do not typically nest; they may inherit from
the top-level system packages or not at all.
For our purposes, it would be convenient to emulate "nested" virtual

distlib is usually not installed on Linux distribution, but it is vendored
into pip. Because the virtual environment has pip via ensurepip, we
can piggy-back on pip's vendored version. This could break if they move
our cheese in the future, but the fix would be simply to
"make check-minreqs" runs pip without the --disable-pip-version-check
option, which causes the obnoxious "A new release of pip available"
message.

our virtual environment rely on "setup.py install" instead of providing

Hey Laurent,
I was having some issues reproducing this bug, but that looks like a likely
explanation!
Should I resubmit the patch with that diff applied?
No, I'm going to update it.
Thanks,

Doesn't apply to current master anymore, and patchew couldn't apply it,
