Introduce a shared vm-core loader and refactor the Ubuntu 26.04 VM script to use reusable helper functions. misc/vm-core.func: add COMMUNITY_SCRIPTS_URL default and load_api_functions to dynamically source API helpers, then call load_api_functions from load_functions. vm/ubuntu2604-vm.sh: switch to sourcing the shared vm-core via COMMUNITY_SCRIPTS_URL, replace many inline UI and utility functions with generic vm_* helpers (vm_confirm_new_vm, vm_prompt_*, vm_select_storage, vm_define_disk_references, set_description, etc.), modernize quoting and pushd usage, simplify disk import/resizing logic, and set START_VM default to yes. Also update repository URLs to ProxmoxVED and adjust some behavior (machine type handling, storage/disk references). Overall this centralizes common functionality, reduces duplication, and prepares scripts to use the shared core utilities.
Introduce interactive whiptail-based helpers and robust error handling for VM creation.
- Add error_handler() to report failures (calls post_update_to_api if available), print contextual error info, and call cleanup_vmid.
- Ensure TEMP_DIR is removed in cleanup().
- Replace brittle pve_check with version parsing that supports Proxmox VE 8.0–8.9 and 9.0–9.1 (exits with code 105 on unsupported versions).
- Add ssh_check() to warn users running the script over SSH.
- Add sanitize_vm_hostname() and a suite of vm_* helper functions to prompt and validate interactive settings via whiptail: vm_confirm_new_vm, vm_choose_settings_mode, vm_prompt_vmid, vm_prompt_machine_type, vm_apply_machine_type, vm_prompt_disk_size, vm_prompt_disk_cache, vm_prompt_hostname, vm_prompt_cpu_model, vm_prompt_cpu_cores, vm_prompt_ram, vm_prompt_bridge, vm_prompt_mac, vm_prompt_vlan, vm_prompt_mtu, vm_prompt_start_vm.
- Add storage helpers: vm_select_storage, vm_apply_storage_layout, vm_define_disk_references to detect storage pools, set formats/extensions and prepare disk refs.
- Use APP/NSAPP for description title by introducing local description_title in set_description().
These changes centralize validation and interactive flow, improve UX, and harden error reporting and cleanup.
Add new icons and message helpers; introduce get_active_logfile and enhance silent() to redirect output to a proper log file (BUILD_LOG or /tmp fallback), preserve/propagate exit codes, temporarily disable traps while running commands, source explain_exit_code for human-friendly error explanations, and show the last 10 log lines on failure. Also sanitize keys when unsetting MSG_INFO_SHOWN to avoid ANSI/control-char issues, add msg_warn and fatal helpers, and make msg_custom skip empty messages. These changes improve observability and robustness of VM creation scripts and error reporting.
