After studying KVM for a long time, I feel like I have used the fastest virtual machine. Compared with common virtual machines, VMWare has comprehensive functions and simple settings, but its speed is not very good. Although virtualbox is more efficient than VMWare, it has many disadvantages, it seems that the CPU is occupied during runn

Preface:
During this time, I have been on a business trip in Mexico. I have encountered various bad things. My weibo followers may all know this, but what I want to say is that there are also some gains, one is that I finally found a little tips on learning English in Mexico at the age of 30; the other is that I have been trying to implement a ceilometer blueprint dur
Dell recently said it will sell consumer desktops and laptops running UbuntuLinux in "the next few weeks". As a result, mainstream consumers will have the opportunity to use open-source operating systems. However, Dell refused to discuss machine configuration issues, so it is not yet known whether it will sell Ubuntu desktops and laptops at a price lower than WindowsPC. Of course,

In the same batch of servers, if such a server is encountered, if it does not run any service, there is no problem, but when a task is run, it is automatically restarted. Since this problem does not occur on other servers of the same system, you can use the quick service code to Find dell after-sales service.

Admittedly, the current large number of consumer digital product design patterns are copied from Apple, whether the process of copying the gradual integration of their own brand characteristics, is the key to success or failure of the product. In one machine desktop computer market, the Apple imac is famous for its fashionable and thin exquisite industrial design, but there are some deficiencies, such as not supporting touch screen. By contrast, Windows producers have more room to play, such as
Nagios monitors dell server hardware
We have mentioned earlier that omsa is used to monitor dell servers, but it must be accessed through web. This time we use nagios + check_openmanage to monitor the hardware of dell servers.
First, let's look at the figure below:

We have previously talked about using OMSA to monitor Dell servers, but must be accessed via the web, and this time we combine nagios+check_openmanage to implement hardware monitoring for Dell servers.First, let's take a look at the following picture:It can be seen in two ways to enable monitoring:The 1.nagios server-side Check_nrpe call is implemented by the monitored check_openmanage, which is installed O

Dell has launched a developer version of the XPS 13 notebook in its official website, with a hardware configuration that is consistent with the Windows version, using the Intel Core i7 processor, 8GB memory and 256GB SSD, and running the Ubuntu 12.04 LTS operating system. In addition, the 1080P screen has some new features, the gamut from the original 45% to 72%, to provide a richer detail performance. The price has not changed, for 1549 U.S. dollars
Kvm Basic Principle 2The idea of KVM is to add a virtual machine management module on the basis of Linux, and reuse the completed process scheduling, memory management, IO management, and other parts in the Linux kernel, therefore, KVM is not a complete simulator, but a kernel plug-in that provides virtualization functions. The specific simulator work is complete
