Transfer of information about the instance hardware

1. To configure the transmission of instance hardware data , it is necessary:

   • Install and configure Nova Virt Driver;
   • Configure collection of information about the hardware of compute nodes by means of the Agent module.

2. When creating instance via Nova Virt Driver, hardware information is transferred to the directory /tmp created instance. The information is presented in two files cpu.info and harware.info:

   • File /tmp/cpu.info contains columns:

     Processor number	NUMA node	Cores

     Where:

     • Processor number is serial number of the instance processor;
     • NUMA node is serial number of the NUMA node, which device belongs to;
     • Cores are serial numbers of compute node processor cores.

   • File /tmp/harware.info contains columns:

     Device model	Device type	NUMA node

     Where:

     • Device model is the device model;
     • Device type is the type of device (for example: network, HBA, FC);
     • NUMA node is serial number of the NUMA node, which device belongs to.
