I have doubts about what to do here, in the sense that we can't easily and reliably set aside memory in the system to run qemu. We could of course check the amount of physical or free memory in the system at the test start time, but there would still be somewhat of a race condition. Also, with tests running in parallel (ie, avocado nrun tests/acceptance/), this would be even trickier... > > + self.vm.add_args('-drive', 'file=%s' % self.boot.path) > > + self.prepare_cloudinit() > > + > > + def prepare_boot(self): > > + self.log.info('Downloading/preparing boot image') > > + # Fedora 31 only provides ppc64le images > > + image_arch = self.arch > > + if image_arch == 'ppc64': > > + image_arch = 'ppc64le' > > + # If qemu-img has been built, use it, otherwise the system wide one > > + # will be used.

Yeah this is a complex case. Maybe for now we can add a tag for the minimum of memory required for a test. Then later it might be easier figure something.

Hmm 'pc' is a confusing alias, kept for backward compatibility... 'q35' is also an alias, see: $ qemu-system-x86_64 -M help Supported machines are: pc Standard PC (i440FX + PIIX, 1996) (alias of pc-i440fx-3.1) pc-i440fx-3.1 Standard PC (i440FX + PIIX, 1996) (default) pc-i440fx-3.0 Standard PC (i440FX + PIIX, 1996) pc-i440fx-2.9 Standard PC (i440FX + PIIX, 1996) ... q35 Standard PC (Q35 + ICH9, 2009) (alias of pc-q35-3.1) pc-q35-3.1 Standard PC (Q35 + ICH9, 2009) pc-q35-3.0 Standard PC (Q35 + ICH9, 2009) pc-q35-2.9 Standard PC (Q35 + ICH9, 2009) pc-q35-2.8 Standard PC (Q35 + ICH9, 2009) ... isapc ISA-only PC none empty machine xenfv Xen Fully-virtualized PC xenpv Xen Para-virtualized PC Historically the 'pc' machine was aiming at modeling a 'PC compatible' machine, as described here: https://en.wikipedia.org/wiki/IBM_PC_compatible We currently have 3 emulated PC machines (excluding the virtual machines such MicroVM, Xen). Some history: - commit 0824d6fc6 The first pc machine is introduced, inside main(). It only use an ISA bus. Today we know this as 'isapc'. - commit 80cabfad1 Refactor, the pc machine is extracted to hw/pc.c - commit 69b910399 PCI support is added. - commit bb0c6722b PCI is used by default. The machine becomes what we today calls 'pc'. - commit b5ff2d6e2 The machine is officially called 'pc'. - commit 3dbbdc255 The 'isapc' machine is added back: it is the 'pc' machine with PCI disabled. - commit df2d8b3ed The 'q35' machine is added. Instead of a i440FX northbridge and PIIX3 southbridge chipsets, it uses a Q35 northbridge and ICH9 southbridge. See: https://wiki.qemu.org/Features/Q35 So 'pc' is more a 'family' of different machines. You can verify the codebase, the abstract parent is in hw/i386/pc.c: static const TypeInfo pc_machine_info = { .name = TYPE_PC_MACHINE, .parent = TYPE_X86_MACHINE, .abstract = true, .instance_size = sizeof(PCMachineState), While the children implementations are hw/i386/pc_piix.c and hw/i386/pc_q35.c (pc_piix.c implements both isapc + i440fx). I'm not sure why one is named by its southbridge chipset, and the other one by its northbridge. I suppose because for a long time the i440fx+piix were mixed in the same file. I cleaned that recently in commits 0fd61a2d1..0f25d865a1: $ git log --oneline --reverse 0fd61a2d1~..0f25d865a1 0fd61a2d1c hw/pci-host/piix: Move i440FX declarations to hw/pci-host/i440fx.h 553b4559dc hw/pci-host/piix: Fix code style issues 14a026dd58 hw/pci-host/piix: Extract PIIX3 functions to hw/isa/piix3.c 0f25d865a1 hw/pci-host: Rename incorrectly named 'piix' as 'i440fx' >>> + """ >>> + :avocado: tags=machine:pc >>> + """ >>> + self.launch_and_wait() >>> + >>> + def test_kvm_pc(self): >> >> This test_pc_i440fx_kvm >> > > Ditto. > >>> + """ >>> + :avocado: tags=machine:pc >>> + :avocado: tags=accel:kvm >>> + """ >>> + if not kvm_available(self.arch, self.qemu_bin): >>> + self.cancel(KVM_NOT_AVAILABLE) >>> + self.vm.add_args("-accel", "kvm") >>> + self.launch_and_wait() >>> + >>> + def test_q35(self): >> >> This one test_pc_q35_tcg >> > > Both *pc* and *q35*?

This acceptance test, validates that a full blown Linux guest can successfully boot in QEMU. In this specific case, the guest chosen is Fedora version 31. * x86_64, pc and q35 machine types, with and without kvm as an accelerator * aarch64 and virt machine type, with and without kvm as an accelerator * ppc64 and pseries machine type * s390x and s390-ccw-virtio machine type The Avocado vmimage utils library is used to download and cache the Linux guest images, and from those images a snapshot image is created and given to QEMU. If a qemu-img binary is available in the build directory, it's used to create the snapshot image, so that matching qemu-system-* and qemu-img are used in the same test run. If qemu-img is not available in the build tree, one is attempted to be found installed system-wide (in the $PATH). If qemu-img is not found in the build dir or in the $PATH, the test is canceled. The method for checking the successful boot is based on "cloudinit" and its "phone home" feature. The guest is given an ISO image with the location of the phone home server, and the information to post (the instance ID). Upon receiving the correct information, from the guest, the test is considered to have PASSed. This test is currently limited to user mode networking only, and instructs the guest to connect to the "router" address that is hard coded in QEMU. To create the cloudinit ISO image that will be used to configure the guest, the pycdlib library is also required and has been added as requirement to the virtual environment created by "check-venv". The console output is read by a separate thread, by means of the Avocado datadrainer utility module.
