The proxmox create task can return before pmxcfs has flushed the .conf, so the first delegated lineinfile hit 'Destination /etc/pve/lxc/<vmid>.conf does not exist'. Poll for the file with wait_for (up to 30s) before applying idmaps/GPU config, which continues as soon as it appears rather than eating a fixed sleep.

# Proxmox's container config parser hoists all comment lines to the top of the
|
|
# .conf on every write (pct set, container start/stop, API calls), which orphans
|
|
# blockinfile's # BEGIN/# END markers and breaks idempotency. Manage the raw lxc.*
|
|
# lines directly with lineinfile instead -- these are real config keys that Proxmox
|
|
# preserves in place. Each line is keyed on its own exact content, so no comment
|
|
# markers are needed and re-runs stay churn-free.
