A guest's parent bind is non-recursive, so a guest reboot leaves enrolled drives bound on the HOST but invisible in the fresh guest ns (propagation only delivers new events). AttachDrive(vmid) now checks GuestSeesMount (/proc/<pid>/mountinfo) and force re-binds (umount+mount) to re-propagate; a 20s periodic reconcile self-heals guest reboots without an agent restart; BoundUnderParent reflects guest visibility (the controller gate's signal). Caught + fixed in the live migration. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
