Davíð Steinn Geirsson	480bfb7095	virtio-devices: balloon: add statistics virtqueue support ... Implement the virtio balloon statistics virtqueue per the VIRTIO spec, exposing guest memory statistics through a new /vm.balloon-statistics API endpoint. Device layer: add stats virtqueue constants and types, wire up the stats queue in the balloon handler, implement stats request/response handlers, and expose a public request_balloon_statistics function. VMM layer: plumb statistics through device manager, VM, and VMM, add HTTP and D-Bus API endpoints, add ServiceUnavailable (503) to api_client, add balloon-statistics subcommand to ch-remote, and add the endpoint to the OpenAPI spec. The response includes both guest-reported stats and host-known values (balloon_actual_bytes, balloon_target_bytes, balloon_total_ram_bytes) so consumers can understand balloon utilization without querying /vm.info separately. Also fixes pre-existing rustfmt issues and adds clippy+rustfmt to the flake devShell. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-22 10:05:19 +00:00
Davíð Steinn Geirsson	e3372a22f6	build: Switch vhost/vhost-user-backend to dsg fork ... Use vhost 0.15.0 and vhost-user-backend 0.21.0 from https://git.dsg.is/dsg/vhost.git instead of crates.io. This required bumping several rust-vmm dependencies to maintain compatibility with the newer vm-memory 0.17.x and vmm-sys-util 0.15.x APIs used by the fork: - kvm-bindings: 0.12.1 → 0.14.0 - kvm-ioctls: 0.22.1 → 0.24.0 (nested_state renamed) - linux-loader: 0.13.1 → 0.13.2 - vfio-bindings: 0.6.0 → 0.6.1 - vfio-ioctls: 0.5.1 → 0.5.2 (VfioDevice::new takes Arc<dyn VfioOps>) - vfio_user: 0.1.1 → 0.1.2 - virtio-queue: 0.16.0 → 0.17.0 - vm-memory: 0.16.1 → 0.17.1 (Error split, Bytes trait, VolatileSlice) - vmm-sys-util: 0.14.0 → 0.15.0 (EventConsumer/EventNotifier API) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-18 17:15:59 +00:00
