Idempotent qm-set script for the per-VM I/O caps on the PVE host's sdc
thin pool (2026-05-26 session, beads code-9v2j). Caps protect each
Linux VM's share of sdc so a runaway workload (e.g. the 2026-05-23/26
alloy IO storm — memory id=2726) cannot saturate the disk for everyone.
Was sitting in /tmp on PVE — moving the source under version control
and installing to /usr/local/bin/ alongside the other PVE operational
scripts (nfs-mirror, daily-backup, offsite-sync-backup; pattern from
memory id=609). Survives PVE host reboots; safe to re-run on any node
rebuild to restore the caps.
VMIDs covered (Linux only — pfSense 101 and Windows10 300 skipped):
