Host

Nodes that run virtual machines are called hosts. This type of host is also called a "compute node". A series of services for managing virtual machines, networks, and storage will run on it.

📄️ Host CPU Reservation

Reserve CPUs on the host for non-virtual machine processes.

📄️ host-deployer Service Introduction

host-deployer is deployed in cloudpods as a daemonset, mainly performing initialization and system detection operations on virtual machine image files. Specific content includes

📄️ Host Enable NUMA Memory Allocation

Normally, when creating virtual machines on a host, the virtual machine's memory is randomly allocated directly from multiple numa on the host by the operating system. After enabling numa memory allocation, the memory on the host will be managed by host-agent, and will try to pre-allocate the numa memory used by the virtual machine before creating the virtual machine as much as possible.
