2019-07-01python/qemu: split QEMUMachine out from underneath __init__.pyJohn Snow
It's not obvious that something named __init__.py actually houses important code that isn't relevant to python packaging glue. Move the QEMUMachine and related error classes out into their own module. Adjust users to the new import location.

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>

2019-01-14hw/misc/ivshmem: Remove deprecated "ivshmem" legacy deviceThomas Huth
It's been marked as deprecated in QEMU v2.6.0 already, so really nobody should use the legacy "ivshmem" device anymore (but use ivshmem-plain or ivshmem-doorbell instead). Time to remove the deprecated device now. Belatedly also update a mention of the deprecated "ivshmem" in the file docs/specs/ivshmem-spec.txt to "ivshmem-doorbell".

Looking closer at the the realize and instance_init function of this device also reveals that it is using serial_hds and nd_table directly there, so this device is clearly not creatable by the user and should be marked accordingly.

2017-06-05scripts: Test script to look for -device crashesEduardo Habkost
Test code to check if we can crash QEMU using -device. It will test all accel/machine/device combinations by default, which may take a few hours (it's more than 90k test cases). There's a "-r" option that makes it test a random sample of combinations. The scripts contains a whitelist for: 1) known error messages that make QEMU exit cleanly; 2) known QEMU crashes. This is the behavior when the script finds a failure: * Known clean (exitcode=1) errors generate DEBUG messages (hidden by default) * Unknown clean (exitcode=1) errors will generate INFO messages (visible by default) * Known crashes generate error messages, but are not fatal (unless --strict mode is used) * Unknown crashes generate fatal error messages Having an updated whitelist of known clean errors is useful to make the script less verbose and run faster when in --quick mode, but the whitelist doesn't need to be always up to date.
