Let's break down the information given. + +First, the host environment is Ubuntu 20.04.3 LTS Desktop running on amd64 architecture. The virtual machine is using QEMU-system-s390x to emulate an s390x environment, which is a mainframe architecture. The guest OS inside the VM is also Ubuntu 20.04.3 LTS Server. + +The problem occurs when running Java, which crashes with SIGILL (illegal instruction) at __kernel_getcpu+0x8 in the vdso. This suggests that there's an issue with how the CPU instructions are being handled. + +Looking into the crash details: The JRE version isn't fully specified, but it's OpenJDK 64-Bit Server VM for s390x. The error happens during the execution of __kernel_getcpu, which is a system call related to getting the current CPU information. This function is part of the kernel, so if it's causing an issue, that points towards lower-level problems. + +Since QEMU is involved, perhaps there's an emulation issue. Maybe the s390x instruction set isn't being properly emulated on the host's amd64 system. The fact that this works on a real IBM LinuxONE III system but not in the VM suggests it's a virtualization problem. + +The crash occurs at a point where Java is interacting with the kernel, specifically during a system call. If QEMU isn't correctly handling certain s390x instructions or if there are issues with how the system calls are being routed through the emulator, that could lead to this illegal instruction error. + +Considering that the problem arises when running Java, which uses the JVM, and that the crash is in a kernel function called by the JVM, it's likely related to how QEMU emulates the s390x architecture at a system level. This would mean it's more of a system-mode issue because it involves interaction between the guest OS and the hypervisor/QEMU. + +So putting this all together: The crash is happening during a system call that Java makes, which isn't being handled correctly by QEMU in the VM environment. Therefore, it's related to how the system is emulated rather than a user-mode application issue. +</think> + +system \ No newline at end of file |
