Conch-Customized Release Notes (2026-05-15)
This release is based on the Cloud Hypervisor main branch, with two critical patches integrated specifically for Conch Sandbox orchestration scenarios.
Core Improvements
-
virtio-devices: Avoid restoring used_idx for unready virtio-pci queues
Description: During the snapshot restoration (Restore) process, if a virtio-pci queue is not yet ready (Ring Addresses are 0), the system will now skip rebuilding next_avail and next_used from used_idx(). -
vmm: Emit 'api-ready' event when API socket is ready
Description: A new event 'vmm'/'api-ready' is now emitted as soon as the VMM API socket is fully initialized and capable of receiving requests.
