Replace virt-customize with a cloud-init custom user-data snippet that installs qemu-guest-agent on first boot. The snippet is SCP'd to the nested PVE's /var/lib/vz/snippets/ and referenced via --cicustom. This eliminates the need for libguestfs-tools entirely — no install on nested PVE, no extra Docker image, no large dependencies. Timeout increased to 300s to allow for cloud-init package installation. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
