Michal Privoznik +Date: Thu, 27 Jan 2022 11:13:53 +0100 +Subject: [PATCH] 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. + +Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2047271 +Signed-off-by: Michal Privoznik
