Wainer dos Santos Moschetta	53a049d7d7	python/qemu: accel: Strengthen kvm_available() checks Currently kvm_available() checks for the presence of kvm module and, if target and host arches don't mismatch. This patch adds an 3rd checking: if QEMU binary was compiled with kvm support.

Wainer dos Santos Moschetta	1650c3e304	python/qemu: accel: Add list_accel() method Since commit `cbe6d6365a` the command `qemu -accel help` returns the list of accelerators enabled in the QEMU binary.

Wainer dos Santos Moschetta	8b272e0018	python/qemu: Move kvm_available() to its own module This creates the 'accel' Python module to be the home for utilities that deal with accelerators.

Wainer dos Santos Moschetta	74b56bb553	python/qemu: Add set_qmp_monitor() to QEMUMachine The QEMUMachine VM has a monitor setup on which an QMP connection is always attempted on _post_launch() (executed by launch()). In case the QEMU process immediatly exits then the qmp.accept() (used to establish the connection) stalls until it reaches timeout and consequently an exception raises. That behavior is undesirable when, for instance, it needs to gather information from the QEMU binary ($ qemu -cpu list) or a test which launches the VM expecting its failure. This patch adds the set_qmp_monitor() method to QEMUMachine that allows turn off the creation of the monitor machinery on VM launch.

Cleber Rosa	0858096702	Python libs: close console sockets before shutting down the VMs Currently, the console socket on QEMUMachine is closed after the QMP command to gracefully exit QEMU is executed. Because of a possible deadlock (QEMU waiting for the socket to become writable) let's close the console socket earlier.

Thomas Huth	976e8c5414	Replace '-machine accel=xyz' with '-accel xyz' We've got a separate option to configure the accelerator nowadays, which is shorter to type and the preferred way of specifying an accelerator. Use it in the source and examples to show that it is the favored option. (However, do not touch the places yet which also specify other machine options or multiple accelerators - these are currently still better handled with one single "-machine" statement instead) Signed-off-by: Thomas Huth <thuth@redhat.com> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20190904052739.22123-1-thuth@redhat.com> Signed-off-by: Laurent Vivier <laurent@vivier.eu>	7 years ago
Max Reitz	4687133b81	iotests: Add @has_quit to vm.shutdown() If a test has issued a quit command already (which may be useful to do explicitly because the test wants to show its effects), QEMUMachine.shutdown() should not do so again. Otherwise, the VM may well return an ECONNRESET which will lead QEMUMachine.shutdown() to killing it, which then turns into a "qemu received signal 9" line.

John Snow	abf0bf998d	python/qemu: split QEMUMachine out from underneath __init__.py 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.

John Snow	9e8dfad045	event_match: always match on None value Before, event_match didn't always recurse if the event value was not a dictionary, and would instead check for equality immediately. By delaying equality checking to post-recursion, we can allow leaf values like "5" to match "None" and take advantage of the generic None-returns-True clause. This makes the matching a little more obviously consistent at the expense of being able to check for explicit None values, which is probably not that important given what this function is used for.

Cleber Rosa	123990adbf	scripts/qemu.py: support adding a console with the default serial device The set_console() utility function either adds a device based on the explicitly given device type, or adds a known good type of device based on the machine type. But, for a number of machine types, it may be impossible or inconvenient to add the devices by means of "-device" command line options, and then it may better to just use the "-serial" option and let QEMU itself, based on the machine type, set the device accordingly. To achieve that, the behavior of set_console() now flags the intention to add a console device on launch(), and if no explicit device type is given the "-serial" option is going to be added to the QEMU command line, instead of raising exceptions. Based on testing with different machine types, the CONSOLE_DEV_TYPES is not necessary anymore, so it's being removed, as is the logic to use it.
