Host Environment Configuration
- Modifying BIOS Settings
You can modify BIOS configuration items of the host to optimize the host for deploying the VM environment. - Modifying the Kernel Module
In the DC1000 GPU hardware environment, the host kernel needs to be adapted for driver installation on the VM. Obtain the kernel source code in advance. - Modifying GRUB Settings
In the GRUB configuration file, enable huge pages on the host to enhance memory management, enable IOMMU passthrough to accelerate memory access, and enable GICv4.1 to reduce CPU consumption and latency and improve virtual drive I/O performance. - Installing VM Dependencies
Install required dependencies on the host where the VM environment is set up. - Querying PCIe Node Information of a GPU
A new Kunpeng 920 processor model processor has four NUMA nodes. Four VMs will be created, and each VM uses resources of a NUMA node of the host. Each NUMA node corresponds to two GPUs. To prevent performance loss caused by cross-NUMA access, you need to confirm the PCIe nodes of GPUs used by each VM before creating VMs. - Configuring the Host Network
Create a host network device to support subsequent VM network configuration.
