With the help of the cat, nano command we can view the CPU configuration file. In the Linux system, the main configuration file of the CPU and system architecture is stored at /proc/cpuinfo. Xen_changeset : Mon Dec 14 12:28:23 2015 +0000 git:87738da-dirty To display CPU information like number of CPUs, cores, threads, NUMA nodes, sockets, information about CPU caches, model, CPU family and stepping and their speed on Linux operating systems. In this article, we will discuss how to check CPU information in a Linux system. It displays a dynamic list of processes sorted by resource. ![]() Xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 The top command provides real-time information about system resource usage, including CPU usage. The server has 2 sockets with 12 cores each and hyper-threading is on, so in total it should have 48 cores, but /proc/cpuinfo, top and lscpu only shows 24 cores and all of the physical ids are 0 but xl info and xl top are showing the correct CPU infoĢ Sockets, 24 Cores with hyper-thread uname ~]# lscpu I've install Xen on CentOS 6.7 on Dell server R620 with no issue, but there is one big thing that I noticed, the CPU information is different depends on how you check it, what the Xen kernel sees is different to what xl info is reporting.
