The first thing to do with the machine is to see if it is vmware. If it is, run the road quickly. Don't fall into the broken jar of others.
Let's see:

Sometimes you need to collect various information about the server, such as CPU information, memory information, Linux version information, and various software information installed. The following describes how to view the main indicators. 1. view the Linux release information [root @ pcmweb ~] # Cat/etc/issue
Red Hat Enterprise Linux Server Release 5 (tikanga)
Kernel on an m2. view Linux kernel information [root @ pcmweb ~] # Uname-R
2.6.18-8. el5xen3. View CPU information [root @ pcmxexdb ~]
How to view cpu, memory, hard disk, and other hardware information in linuxNote: in Linux, you can view detailed information about each cpu in/proc/cpuinfo. However, for dual-core CPUs, two CPUs are displayed in cpuinfo. It is often mistaken for two single-core CPUs.I. linux CPU size

The windows in the Performance tab CPU Usage records in the window task management were puzzled. Why some computers show 1 windows, some computer shows two, and the server has some display window even 16, 24 more that.
I have been told that there are 1 representatives of the CPU is a single core, and two represents the CPU is dual-core. That server has 16, whether it represents the server is 16 core that.
