Environment Requirements

This document provides guidance based on the openEuler OS. Before performing operations, ensure that your hardware and software meet the requirements.

Hardware Requirements

Table 1 lists the hardware requirements.

**Table 1** Hardware requirements
Item	Description
Processor	Kunpeng 920 series processors

OS and Software Requirements

Table 2 lists the OS and software requirements.

**Table 2** OS and software requirements
Item	Version	How to Obtain
OS	openEuler 20.03 LTS SP1 The minimum OS version requirement applies to both physical and virtual machines.	Link
libvirt	6.2.0 or later	Install it using the Yum tool.
QEMU	4.1.0 or later	Install it using the Yum tool.

**Table 3** Patch requirements for non-openEuler kernels
No.	Patch	How to Obtain
1	KVM: arm64: Document PV-sched interface	Link
2	KVM: arm64: Implement PV_SCHED_FEATURES call	Link
3	KVM: arm64: Support pvsched preempted via shared structure	Link
4	KVM: arm64: Add interface to support vCPU preempted check	Link
5	KVM: arm64: Support the vCPU preemption check	Link
6	KVM: arm64: Add SMCCC PV-sched to kick cpu	Link
7	KVM: arm64: Implement PV_SCHED_KICK_CPU call	Link
8	KVM: arm64: Add interface to support PV qspinlock	Link

This feature depends on support from both physical and virtual machines. For non-openEuler kernels, the specified patches must be installed on both sides.
