qemu: Build command line for virtio-mem Nothing special is happening here. All important changes were done when for 'virtio-pmem' (adjusting the code to put virtio memory on PCI bus, generating alias using qemuDomainDeviceAliasIndex(). The only bit that might look suspicious is no prealloc for virtio-mem. But if you think about it, the whole purpose of this device is to change amount of memory exposed to guest on the fly. There is no point in locking the whole backend in memory. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>

qemuxml2argvdata: Use proper arch and emulator for x86 real capability tests Upcoming patches will modify how we populate the capability cache in tests to be more saner. This also means that the emulator binary and architecture used in the test files using real capabilities must match what the real capabilities have.

qemu: Switch to -accel We currently use -machine accel=XXX which is just a syntax sugar for -accel XXX. The former doesn't allow specifying arguments for accelerator, because all arguments passed to -machine are treated as arguments of machine itself. The -accel argument was introduced in QEMU commit v2.9.0-rc0~70^2~19 and since our minimum required version is newer (2.11.0) we can safely assume its existence and use it without any capability.

qemu_command: Generate memory only after controllers Currently, memory device (def->mems) part of cmd line is generated before any controller. In majority of cases it doesn't matter because neither of memory devices live on a bus that's created by an exposed controller (e.g. there's no DIMM controller, at least not exposed). Except for virtio-mem and virtio-pmem, which do have a PCI address. And if it so happens that the device goes onto non-default bus (pci.0) starting such guest fails, because the controller that creates the desired bus wasn't processed yet. QEMU processes arguments in order. For instance, if virtio-mem has address with bus='0x01' QEMU refuses to start with the following message: Bus 'pci.1' not found Similarly for virtio-pmem. I've successfully tested migration and changing the order does not affect migration stream.
