2019-02-22Introduce a Python module structureCleber Rosa
This is a simple move of Python code that wraps common QEMU functionality, and are used by a number of different tests and scripts. By treating that code as a real Python module, we can more easily: * reuse code * have a proper place for the module's own unittests * apply a more consistent style * generate documentation Signed-off-by: Cleber Rosa <crosa@redhat.com> Reviewed-by: Caio Carrara <ccarrara@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Message-Id: <20190206162901.19082-2-crosa@redhat.com> Signed-off-by: Cleber Rosa <crosa@redhat.com>
2019-02-11tests/vm: Be verbose while extracting compressed imagesPhilippe Mathieu-Daudé
Depending of the host hardware, copying and extracting VM images can take up to few minutes. Add verbosity to avoid the user to worry about VMs hanging.

2019-02-08tests/vm: expose BUILD_TARGET, TARGET_LIST and EXTRA_CONFIGURE_OPTSAlex Bennée
Now the underlying basevm support passes these along we can expose some additional variables to our Makefile to allow more customised tweaking of the build. For example: make vm-build-freebsd TARGET_LIST=aarch64-softmmu \ EXTRA_CONFIGURE_OPTS="--disable-tools --disable-docs" \ BUILD_TARGET=check-softfloat Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com>
2019-02-08tests/vm: add --build-target optionAlex Bennée
This allows us to invoke the build with a custom target (for the VMs that use the {target} format string specifier). Currently OpenBSD is still hardwired due to problems running check.

2019-02-08tests/vm: call make check directly for netbsd/freebsd/ubuntu.i386Alex Bennée
The "make check" target calls check-qtest which has the appropriate system binaries as dependencies so we shouldn't need to do two steps of make invocation. Doing it in two steps was a hangover from when our make check couldn't run tests in parallel.

2018-08-24tests/vm: Increase timeout waiting for VM to boot to 5 minutesPeter Maydell
The VM tests currently have a timeout of 2 minutes for trying to connect to ssh. Since the guest VM has to boot from cold to the point of accepting inbound ssh during this time, if the host machine is heavily loaded it can spuriously time out.

2018-08-15tests/vm: Bump guest RAM up from 2G to 4GPeter Maydell
Currently we run the guests in a VM which is given only 2G of RAM. Since the guests are configured without any swap space, builds can fail because the system runs out of memory and kills the compiler, especially if the job count is set for a lot of parallelism. Bump the setting up from 2G to 4G to give us some more headroom.

2018-02-08docs: Add docs/devel/testing.rstFam Zheng
To make our efforts on QEMU testing easier to consume by contributors, let's add a document. For example, Patchew reports build errors on patches that should be relatively easy to reproduce with a few steps, and it is much nicer if there is such a documentation that it can refer to. This focuses on how to run existing tests and how to write new test cases, without going into the frameworks themselves. The VM based testing section is moved from tests/vm/README which now is a single line pointing to the new doc.

2017-10-11basevm: Call logging.basicConfig()Eduardo Habkost
Just setting level=DEBUG when debug is enabled is not enough: we need to set up a log handler if we want debug messages generated using logging.getLogger(...).debug() to be printed. This was not a problem before because logging.debug() calls logging.basicConfig() implicitly, but it's safer to not rely on that.
