- Playbook: detect interface already configured with 10.9.100.1 before falling back to non-default-gateway heuristic (fixes dnsmasq binding to wrong NIC when multiple interfaces exist) - test-vm.sh: auto-attach br-pxe bridge NIC if available on host - Webapp: add network upload import via SMB share with shared driver deduplication and symlinks Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# test-vm.sh — Create a test VM to validate the PXE server setup
|
|
#
|
|
# This script:
|
|
# 1. Builds a CIDATA ISO with autoinstall config, packages, playbook, and webapp
|
|
# 2. Launches an Ubuntu 24.04 Server VM on the default libvirt network
|
|
# 3. The VM auto-installs, then runs the Ansible playbook on first boot
|
|
#
|
|
# Usage:
|
|
# ./test-vm.sh /path/to/ubuntu-24.04-live-server-amd64.iso
|
|
#
|
|
# After install completes (~10-15 min), access via:
|
|
# virsh console pxe-test (serial console, always works)
|
|
# ssh pxe@<dhcp-ip> (check: virsh domifaddr pxe-test)
|
|
#
|
|
# To clean up:
|
|
# ./test-vm.sh --destroy
