They mention that version 2.3.0 works fine under the same conditions. The problem occurs during the SeaBIOS screen, specifically when it says "Press F12 for boot menu." + +Looking at the provided command line, they're using several vfio-pci devices, including one for their GPU at 04:00.0. They also mention that removing the GPU passthrough doesn't resolve the issue because QEMU still starts but the VM won't boot. + +The user's environment includes an AMD FX-8150 CPU and a Gigabyte GA-990FXA-UD5 motherboard with a 990FX chipset. The lspci output shows they're using Radeon R7 260X and HD 6770 GPUs, which are both AMD cards. + +In the release notes for QEMU 2.4.0, there's mention of support added for resetting AMD Bonaire and Hawaii GPUs, as well as platform device passthrough for Calxeda xgmac devices. The user suggests that something in these changes might have caused their issue. + +Now, considering the categories: mistranslation, assembly lowering, device, graphic, etc. Since the bug is related to VFIO and pci passthrough specifically with a graphics card, it's pointing towards an issue with how the GPU is being handled under vfio-pci. + +VFIO (Virtual Function I/O) is used for direct assignment of PCIe devices to VMs. Issues here often relate to device drivers or hypervisor support rather than user-mode translations or assembly code. The problem isn't about assembly lowering, so that category doesn't fit. + +The hanging occurs during the GPU passthrough, which suggests it's a hardware-related issue in QEMU's handling of the VFIO devices. Therefore, it falls under the 'device' category as it pertains to device assignment and management within the hypervisor. +</think> + +The bug report is related to device passthrough using VFIO for a graphics card, leading to a hang in QEMU 2.4.0. This points directly to an issue with how devices are handled under vfio-pci. + +**device** \ No newline at end of file |
