Let me go through this step by step. - -First, the error messages are pointing to functions in `oslib-posix.o` that can't find the trace functions. This suggests that either those trace functions aren't being generated correctly or the build process isn't including them properly. - -Looking at the git status output provided, I see that there are untracked files: `libhw32/`, `libhw64/`, `trace.c`, and `trace.h`. These might be leftover files from a previous build. Sometimes, old files can cause issues if they're not cleaned up properly. - -The user mentioned trying `make distclean` and re-running the configure script followed by make again. But the problem persists. Maybe there are still some stale files lingering around that aren't being removed during the clean process. - -Stefan suggested removing `trace.c` and `trace.h`. I remember that QEMU generates these trace files automatically based on the code, so having them manually present might be conflicting with the generated versions. If those files exist in the repository or are part of a previous build, they could cause the linker to look for symbols that aren't being defined anymore. - -Another thought: perhaps after updating QEMU, some other supporting files weren't updated correctly. The `libhw32` and `libhw64` directories might contain old object files or static libraries that are still being included during linking, even though they're not needed anymore. Cleaning these out could help avoid such conflicts. - -I should also consider whether the Makefile is correctly handling all generated files. If there's a reference to the old `trace.h` in the Makefile or include paths, it might be causing the build system to look for those undefined functions in the wrong place. - -To test this theory, I'll proceed with removing the untracked `trace.c` and `trace.h` files as suggested. Then, perform a clean build again by running `make distclean`, reconfigure, and make. If that works, then the stale trace files were indeed causing the problem. - -Additionally, after cleaning up, I should check if any other old or unnecessary files are present in the directory that might still be affecting the build process. Sometimes, even after a clean, certain artifacts can remain which cause unexpected issues. -</think> - -The issue arises because the QEMU build process is referencing stale `trace.c` and `trace.h` files from a previous build, causing undefined reference errors. These files should be generated automatically during compilation but are instead being treated as existing source files. - -**Solution:** - -1. **Remove Stale Trace Files:** - - Delete the manually present `trace.c` and `trace.h` files to prevent them from interfering with the build process. - -2. **Perform a Clean Build:** - - Run `make distclean` to remove all object files and other generated files. - - Re-run the configure script with the necessary flags. - - Execute `make` to rebuild QEMU. - -**Steps:** - -- Remove the stale trace files: - ```bash - rm trace.c trace.h - ``` - -- Perform a clean build: - ```bash - make distclean && ./configure --enable-linux-aio --enable-kvm --enable-vhost-net && make - ``` - -By removing the old `trace` files and doing a fresh build, you ensure that QEMU generates the correct trace functions, resolving the undefined reference errors. \ No newline at end of file diff --git a/results/classifier/deepseek-1/reasoning/errors./1752026 b/results/classifier/deepseek-1/reasoning/errors./1752026 deleted file mode 100644 index 40408e991..000000000 --- a/results/classifier/deepseek-1/reasoning/errors./1752026 +++ /dev/null @@ -1,147 +0,0 @@ -<think> -Alright, I need to figure out how to approach this problem with the KVM guests on Ubuntu 18.04 using PowerPC. The user mentioned that they can't boot an Ubuntu 14.04.5 guest in Power8 compatibility mode on a Boston P9 DD2.2 system. They also provided some context about changes made in the kernel related to KVM and PPC, specifically allowing HPT and radix on the same core for POWER9 v2.2. - -First, I should understand what each part of this means. KVM is a virtualization technology that allows running guest operating systems as virtual machines. On PowerPC systems, there are different modes like HPT (hashed page tables) and radix (another form of page table). For compatibility with older POWER8 guests on newer POWER9 hardware, the system needs to handle both HPT and radix correctly. - -The user's issue is that when trying to boot an Ubuntu 14.04.5 guest in Power8 mode on a P9 system, it fails. They applied a kernel patch that allows both HPT and radix on the same core for POWER9 v2.2. I need to test whether this fix works. - -I should start by setting up the environment. Since I'm using Ubuntu 18.04 (Bionic) as the host, I'll enable the -proposed kernel to include the necessary patches. Then, I'll set up KVM and try to launch a PowerPC guest in compatibility mode. - -Here's what I need to do step by step: - -1. **Enable the Proposed Kernel**: In Ubuntu, to test the proposed packages, I can add the `ubuntu-proposed` repository and update my system. This way, when I install the kernel from -proposed, it includes the latest fixes. - - ```bash - sudo add-apt-repository proposed - sudo apt update - ``` - -2. **Install the Updated Kernel**: Install the new kernel package. It's usually named something like `linux-image-generic` with a version indicating it's from -proposed. - - ```bash - sudo apt install linux-image-generic/ubuntu-proposed - ``` - -3. **Reboot into the New Kernel**: After installation, reboot the system to use the new kernel. - -4. **Set Up KVM for PowerPC Guests**: Ensure that I have the necessary QEMU and KVM tools installed. On Ubuntu, this typically includes packages like `qemu-system-powerpc64le` or similar, depending on the architecture. - -5. **Prepare the Guest Image**: Create or obtain an Ubuntu 14.04.5 ISO image suitable for a PowerPC guest. Make sure it's compatible with KVM and that the system can boot from it. - -6. **Launch the KVM VM in Compatibility Mode**: - - I'll use the following QEMU command to launch the guest: - - ```bash - qemu-system-powerpc64le \ - -M pseries-v2.0 \ - -cpu POWER9,compat=power8 \ - -m 1024M \ - -smp 1,cores=1 \ - -drive if=pflash,driver=raw,file.driver=stdio,format=raw, file.filename=openpowerkvm-ppc64le-boot.iso \ - -net none \ - -nographic - ``` - - Here, I specify the machine type `pseries-v2.0`, set the CPU to POWER9 with compatibility mode for POWER8, allocate 1GB of RAM and one core, and attach the guest ISO as a pflash drive. - -7. **Observe Boot Behavior**: After starting the VM, check if the guest OS (Ubuntu 14.04.5) boots successfully. If it doesn't, look for any error messages during the boot process that might indicate issues with hardware initialization or virtualization support. - -8. **Check Kernel Logs on Host**: If the guest fails to boot, inspect the host's kernel logs to see if there are any relevant errors or warnings related to KVM or PPC operations. - - ```bash - dmesg | grep -i kvm - ``` - -9. **Verify HPT and Radix Configuration**: Since the fix allows both HPT and radix on the same core, I should check whether the kernel is correctly handling this configuration when running a Power8 guest on POWER9 hardware. - -10. **Reproduce the Issue Without the Fix**: To ensure that the problem has been fixed, it might help to test without the proposed kernel as well, but since the fix is already applied, this might not be necessary unless I suspect other factors are at play. - -11. **Log Any Errors or Output**: If the guest fails to boot, capture the output from QEMU and any relevant logs to provide more context for troubleshooting. - -Potential issues to consider: - -- **Kernel Module Support**: Ensure that all necessary kernel modules for KVM and PowerPC virtualization are loaded on the host. - - ```bash - lsmod | grep kvm - ``` - -- **BIOS/UEFI Settings**: Sometimes, hardware virtualization settings need to be enabled in the BIOS. On some systems, you might need to enable "Nested Virtualization" or similar features. - -- **Guest OS Compatibility**: Ensure that the guest OS is properly configured to run under KVM and supports the necessary virtualization extensions. - -- **HWMPTE (Hardware Multi-TLB Page Table Extension)**: Since HPT relates to TLB management, any issues here could cause boot failures.
