Mem: 133987708k total, 19683300k used, 114304408k free CPUs: 48 2600MHz The cpufreq-info command is a utility in Linux that is used to display information about the CPU frequency scaling capabilities of a system. To get clock speed information, there is no standard tool. The command glxinfo will give you all available OpenGL information for the graphics processor, including its vendor name, if the drivers are correctly installed. Xen_commandline : dom0_mem=1024M,max:1024M cpuinfo com1=115200,8n1 console=com1,tty loglvl=all guest_loglvl=allĬc_compiler : gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-16)Ģ domains: 1 running, 0 blocked, 0 paused, 0 crashed, 0 dying, 0 shutdown That type of information is non-standard, and the tools you will use to gather it vary widely. lscpu command to display CPU information in parsable format. Display the CPU information in human-readable format with lscpu command. 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. ![]()
