Worked on the lima-vm/lima repository to address non-deterministic QEMU boot order issues in virtual machines. Introduced explicit drive configurations and managed bootindex settings to ensure the primary disk is consistently prioritized during VM startup, even when multiple bootable disks are present. Extended support to the s390x architecture by aligning drive selection with existing network device patterns, and incorporated ISO-aware logic to prevent installation failures caused by QEMU boot semantics. Utilized Go for system programming tasks and leveraged expertise in virtualization and QEMU to deliver more reliable OS installations and reduce manual troubleshooting for cross-architecture virtual machine environments.
