Description:

# Total Logical CPUs = number of physical CPUs x number of cores per physical CPU X number of hyper-threads
# If the CPU has the same number of cores as the logical number, it means that the CPU does not have hyper-threading and vice versa, as in this case the CPU is a double-threaded

Querying memory information

1. View Memory Models

5. Tools Introduction

   Most of the servers are configured with array cards, raid on the hard disk, can be megacli this tool for command query array card and hard disk information (installation package see attachment)

   Megacli64-cfgdsply-aall

   The RAID model corresponding table information is as follows:

   RAID level:primary-1, Secondary-0, Raidlevel Qualifier-0 "#代表Raid 1

   RAID level:primary-0, Secondary-0, raidlevel Qualifier-0 "#代表Raid 0

   RAID level:primary-5, Secondary-0, Raidlevel Qualifier-3 "#代表Raid 5

   RAID level:primary-1, Secondary-3, Raidlevel Qualifier-0 "#代表Raid10

   
   

KVM Virtual machine configuration information Query

KVM Virtual Machine Default configuration file location:/etc/libvirt/qemu/

Example:

Cat/etc/libvirt/qemu/vm050.xml

As can be seen from the above information, the virtual machine vm050 memory is 8g,cpu logical number is 4, the hard disk virtual file path is/data/vmdisk/tmpl.sys.img

by command qemu-img info/data/vmdisk/tmpl.sys.img, you can query the size of the virtual hard disk, as follows
