Label:Recently began to learn OpenStack, because there is no environment, so do not know how to get started, so download the OpenStack for Oracle Linux version, ready to play (with Oracle account, hehe). This reference is still a lot of information on the Oracle website, I refer to the Ronen Kofman hands-on lab:getting Started with OpenStack on Oracle Linux and Oracle VM , the link is as follows: Http://www.oracle.com/technetwork/systems/hands-on-labs

connected to the actual network, for example, eth0. The specific method is to modify the NIC configuration file under the/etc/sysconfig/network-scripts directory, such as binding etho, then modify the ifcfg-eth0 and ifcfg-virbr0 The modified configuration file is as follows: 1) ifcfg-eth0 Device = eth0Onboot = YesBridge = virbr0Bootproto = DHCPType = Ethernet 2) ifcfg-virbr0Device = virbr0Type = BridgeOnboot = YesDelay = 0Bootproto = noneIpaddr = 10.100.0.3Netmask = 255.255.255.0Gateway = 10.10

After the memory is allocated to the virtual machine, the Hyper-V host allocates the available memory resources of the system to the created virtual machine. The default memory is called static memory, that is, when you create a virtual machine, how much GB of memory is allocated to the virtual machine. The dynamic memory function provided by Windows Server 2012 Hyper-V allows the Administrator to re-adjust resources, make full use of limited memory resources to achieve better memory integration

From: http://archives.opennebula.org/documentation:archives:rel2.2:cong There are two contextualization mechanic ISMs available in opennebula: the automatic ic ip assignment, and a more generic way to give any file and configuration parameters. You can use any of them individually, or both.Using Virtual Network leases within a virtual machine With opennebula you can derive the IP address assigned to the VM from the MAC address using the mac_preffix: I

The two modules to be introduced today are assert and VM. Next we will introduce them separately. 　　Use assert for testing Node, we can use the assert module to test the code. Equal () and notequal () are used to determine equality and inequality respectively. The first parameter is the expected value, the second parameter is the real value, and the third parameter is the exception information. The example is as follows: var assert = require('assert')

VMware workstation/fusion are the corresponding desktop virtualization software under Windows/linux and MacOS respectively. In the past, after installing an operating system virtual machine in VMware, it was necessary to install the VMware Tools Enhancement tool in the virtual machine to enable file sharing between host and virtual machines, virtual machine display resolution adaptive tuning, virtual machine display capability enhancement and 3D acceleration. But with the development of the Lin

I will give you a detailed explanation of the proc directory recently. You are welcome to translate it. If you have any questions, leave a message. Although it is in English, it is easy to understand. If you have any questions, please leave a message and we will work together for the Linux community. Our translation effect is not necessarily good, because it is done by foreigners after all !!! Giggling, translation may cause misunderstanding. Understanding this requires TCP/IP knowledge. Learnin

VMware command line control VM I haven't used the vmwarevm for a long time. Today I want to install an XP instance for testing. It's too slow to install it with virtualpc. If I don't wait for a long time, I will install it with Vmware, which is much faster than virtualpc. After the installation is complete, it is important to enable the host operating system to automatically start the specified virtual machine for running. The keyword is a command l
