Supports Batch VM Migration
Starting from ZStack Cloud 5.5.0, you can migrate VM instances in batches, simplifying large-scale operations such as planned maintenance, storage expansion, and load rebalancing. You can specify a common target host or primary storage for a batch VM instances, or specify targets individually, balancing efficiency with operational flexibility.
Additionally, migration entry points are now available on the Associated Resource tab in the host or primary storage details page. This allows you to initiate batch migration directly based on the associated hosts or primary storage, providing richer operational perspectives and a more convenient user experience.



Cloud Network
Supports SDN Instance HA
Starting from ZStack Cloud 5.5.0, the SDN module introduces a new resource type: the SDN cluster. An SDN cluster is a group of dedicated VM instances designed to provide highly available SDN capabilities.
Flexible Deployment Modes
- Cluster Mode (Recommended for production environments)
- The system automatically creates an SDN cluster containing 3 nodes.
- All nodes in the cluster have the same instance offering and are deployed on the same primary storage.
- The system uses an anti-affinity policy to ensure the 3 nodes are scheduled to run on different hosts, effectively preventing network function anomalies caused by host failures.
- Single-Node Mode (Suitable for development, testing, or lightweight
environments)
- The system creates a single-node SDN instance, whose behavior is identical to the legacy SDN Instance.
Enhanced Monitoring and Operations
- Supports visualization and monitoring of the SDN cluster as a whole and its internal nodes. You can intuitively view the health status of the cluster and nodes, facilitating rapid fault identification by operations staff.
- A new SDN cluster maintenance mode is added. In maintenance mode, you can perform operations such as adding, rebooting, or deleting instances within the cluster.

Dual-NIC Bond Support for SR-IOV Virtualization and Restoration
Starting from ZStack Cloud 5.5.0, SR-IOV is supported on dual-NIC bonds. You can configure VF NICs based on dual-NIC bonds for VPC vRouters, thereby achieving both the network performance of hardware passthrough and high availability.
