- Update ISO to ubuntu-24.04.4, hardcode SHA256 checksum (24.04.2 removed from mirrors) - Remove headless variable (not declared in QEMU-only HCL, QEMU is always headless) - Add qcow2-to-kvm.sh post-processor for KVM/libvirt/Proxmox deployments - Add qcow2-to-ova.sh (converts qcow2 → stream-optimized VMDK → OVA without ovftool) - packer validate now passes cleanly Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
