Let's see what the issue is. + +The problem occurs when running OpenIndiana (and related) guests on AMD hardware using qemu-kvm 1.1.1. The user mentioned that it works fine on Intel hardware but fails on AMD. They tried different configurations, like changing the VGA and CPU types, but nothing worked. + +Looking at the symptoms: GRUB loads, offers boot options, but none work. There's a kernel panic with a message about a double fault (type=8) and some specifics about the CPU state. The panic happens during the VM's startup. + +The categories I have are: mistranslation, assembly, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, and other. + +First thought: since it's a boot issue on AMD hardware, but works on Intel, it might be related to how QEMU handles certain CPU instructions or features when emulating for AMD versus Intel. Maybe the virtualization isn't correctly handling something specific to AMD processors during the boot process. + +The panic mentions a double fault, which is a type of trap in the CPU. This could indicate an issue with how the hypervisor (QEMU/KVM) is handling exceptions or traps on AMD hardware. Alternatively, it might be a problem with the kernel mode execution or the way virtualized CPUs are set up. + +I'm leaning towards 'kernel' because the panic occurs during the OS boot process, and it's related to the CPU's exception handling, which is managed by the kernel in the guest OS. However, since QEMU/KVM is the hypervisor, maybe it's a problem with how KVM interacts with the host's AMD CPUs when running Solaris guests. + +But considering that OpenIndiana is based on Solaris and the issue occurs during boot, perhaps the bug lies within how the hypervisor (KVM) handles certain CPU features or traps on AMD hardware. Alternatively, it could be related to the kernel mode of the guest OS not being handled correctly by QEMU's emulation for AMD. + +Another angle: since the user tried different emulated CPUs without success, maybe it's a problem with the CPU model in QEMU when using 'host' mode (-cpu host) on AMD. This might fall under 'mistranslation' if there's an issue mapping the source architecture (AMD) to the target IR. + +Wait, but 'mistranslation' is specifically about incorrect semantic mapping from source to target in user-mode assembly lowering. Here, it's more about booting and kernel panics, which might be a kernel-related issue or hypervisor handling. + +Alternatively, the problem could be under the 'boot' category since it's related to the guest not booting properly. But I'm not sure if that's specific enough. + +Another possibility: this is a kernel mode issue in the host, but the category doesn't have a direct match for that. Looking back at the categories, perhaps 'hypervisor' would be appropriate because KVM is the hypervisor and it might not correctly handle AMD-specific exceptions during guest booting. + +So, considering all these points, the bug seems related to how QEMU/KVM handles certain CPU traps or exceptions on AMD hardware when running Solaris-based guests. This likely falls under 'hypervisor' category. +</think> + +The issue is related to how QEMU/KVM handles exceptions during boot on AMD hardware, which affects the hypervisor's ability to manage guest OS correctly. + +**Answer:** + +hypervisor \ No newline at end of file |
