BoostVirt

Describes the latest updates in documents of BoostVirt.

Accelerates CPU scheduling for applications on VMs based on hardware-software collaboration.

Activates GICv4.1 to enhance the interrupt management mechanisms, improving interrupt processing efficiency in virtualized environments.

Allows the GIC to skip VMOVP instructions when vCPUs are migrated between CPUs that share the same virtual processing element (vPE) table, thus improving VM service performance in overcommitment scenarios.

Allows a physical function (PF) to be configured with interrupt translation services (ITSs) that virtual functions (VFs) can use. The kernel can then determine the ITSs used by VFs, achieving ITS load balancing.

Provides a hardware acceleration solution based on the Kunpeng processor, including KAE encryption and decryption and KAEzip. It supports live migration of KAE passthrough devices, expanding the application scenarios of KAE devices.

Dynamically adjusts memory capacity and vCPU quantity for running VMs.

Replaces the native zlib library with KAE to accelerate VM live migration.

Enables PMU events to be collected on a VM, which helps analyze and tune the performance of the VM OS and service software.

Enables the MPAM feature on libvirt and restricts the resource usage of VMs through XML configuration.

Maintains VM operation and service continuity during hardware upgrades by supporting VM migration between different hardware generations.

Isolates single-core corrected errors (CEs) online, and allows uncorrected errors (UEs) in a single page of memory to affect only one process in a VM, ensuring long-term stable system running.

Supports ZRAM-based memory compression, huge-page memory reclamation, and cold and hot page swapping, ensuring that the performance deterioration is less than 15% when memory overcommitment is enabled.

Automatically manages all KAE devices on the server and simplifies the passthrough operations of the KAE devices.

Offloads time-consuming encryption and decryption operations from the CPU to KAE to accelerate encryption and decryption while releasing CPU computing power for other service workloads.

Automatically manages and implements passthrough for SR-IOV devices using the Kubernetes device plugin mechanism.

Adds the NUMA affinity mechanism to Kubernetes container overcommitment scenarios to improve the container performance.

Supports MPAM-based memory access isolation and control, and the SMT QoS interface, reducing the interference of offline services to online services.

Perceives the running load of service containers and dynamically adjusts container parameters to ensure the optimal configuration in real time.
