An idle Windows VM was suspending itself off the network after 15 min: the Balanced power plan sleeps on idle, and the qemu S3/S4 disable was a no-op -- `-global ICH9-LMB.disable_s3` is the wrong device class (q35's bridge is ICH9-LPC), which qemu rejected as "invalid class name", so the sleep states stayed on offer. Fix both ends: correct the global to ICH9-LPC so the firmware stops advertising S3/S4, and in post-oobe (any enableRDP image) switch to the High Performance scheme, zero the standby/hibernate/monitor idle timeouts and turn hibernate off -- a machine exposed as a service must not sleep.
