/proc provide the latest information about the physical environment of the system. Although files in/proc are virtual, they can still be viewed using any file editor or programs such as 'more', 'less ', or 'cat. When the editing program tries to open a virtual file, the file is created out of thin air by the information in the kernel. Here are some interesting results I got from my system:$ Ls-l/proc/cpuinfo-R -- 1 root 0 Dec 25 :01/proc/cpuinfo$ File/proc/cpuinfo/Proc/cpuinfo: empty$ Cat/proc/c

about it. That is to say, when KVM is used for bridge, there is a small problem and we will record it. By default, KVM is not installed. Before installation, check whether the CPU supports the VT technology. 1. Switch to the root ModeBy default, the ubuntu root account is not enabled. To enable it, you need to make some settings. For installation convenience, enable the root account.Sudo passwd rootAfter the password is entered, the su root enters the master mode. 2. Check CPU InformationEgrep

blocked. the system may not be able to respond to the ping request. because a CPU can no longer respond to the interruption, the scheduled interruption of the local APIC on it cannot work. You can use the NMI Watchdog method to check the counter variable maintained by the local APIC handler ), NMI Watchdog can call panic () in its processing program, so that users can use kdump to collect memory informatio

Linux core is an important time-related domain name or change. The following describes Hz, tick, and jiffies. Hz In Linux, the kernel sends the timer interrupt (IRQ 0) Every fixed period. Hz is used to determine that there are two times of timer interrupts every second. In the example, Hz is 1000, indicating that there are 1000 timer interrupts requests per second. Hz can be set when the core is updated, as shown in the following example (the core version is 2.6.20-15 ): Adrian @ Adrian-deskto

To virtualize multiple Ubuntu servers on one server, it is used for clusters. Several solutions have been taken into consideration. Because of the exclusion of the price, virtualbox is good, but KVM is a Linux kernel layer and delivers better performance. Use is preferred. First, install Ubuntu 12.04 amd64 server on an experimental machine. Upgrade the system patch and kernel. The hostname is kvmhost. The IP address is 10.112.18.177. The virtualization function is enabled on the motherboard. Oka

Considering the compatibility and the usage of 4G memory in Ubuntu, a 32-bit system is selected. The installation of the USB flash drive is ready-made, and it is easy to handle the problem. The result has been tossing for several days. The main board, graphics card, and wireless network card are all tricky. The first problem with t

I used to draw a memory distribution chart with some macro definitions of kernel memory management.Such as vmalloc_start, vmalloc_end, and fixaddr_start.I always thought that these values had more or less errors in the actual kernel. I did not expect to read them a few days ago.They are completely consistent. To calculate the total vmalloc size, we think that 1 GB of kernel space starts from 0.First, my physical memory exceeds 896 MB, so high_memory is 896 MB.8 m holes are used to capture out-of

Several important terms or variables related to time in Linux are described below: Hz, tick, and jiffies. (1) Hz The Linux kernel sends timer interrupt (IRQ 0) Every fixed period. Hz is used to define the number of times timer interrupts is generated every second. For example, if Hz is 1000, there are 1000 timer interrupts requests per second. Hz can be set when the core is compiled. For details about the query setting method, see the previous article "How long has it been running in Linux". Hz
