First, start the clone-friendly system. Modify the hostname so that it is not the same as the original host name. vim/etc/sysconfig/network (rhel-6) Network adapter configuration file, modify the IP address, and delete the MAC address. Vim/etc/syconfig/network-script/ifcfg-eth0 Delete the Mac file. rm-rf/etc/udev/rules.d/70-persistent-net.rules Reboot the system and you're ready. The above is the operation of RHEL6 or CENTOS6, 7 is the same. How to configure virtual machine

Tutorial on modifying network configuration After cloning centos6 Virtual Machine in Linux, linuxcentos6 This configuration is based on centos6. Generally, when you directly clone a VM and execute ifconfig on the obtained Vm, the IP address is usually not displayed. This is because we still lack some configuration. The configuration is as follows: 1) modify the network address (1) edit file vi/etc/sysconfig/network-scripts/ifcfg-eth0 Network Service r

C # Introduction to replication and cloning, If there are similarities, we will be honored. If you reprint them, please note In C #, we will talk about using HashTable, DataTable, and other copies and clones. Let's look at the example below. HashTable ht = null; Ht = new HashTable (); Foreach (string s in ht) { //... } // The key value in HashTable needs to be modified during the previous traversal. Generally, an exception is reported, prompting you

Therefore, if you want to create an object with the same content as an existing object, you cannot simply assign values. This may be hard to understand. See the following example:CopyCodeThe Code is as follows: var A = [1, 2, 4]; var B = A; C = B;. pop (); // remove the last element alert (B); // pop up 1, 2, 3 alert (c); // pop up 1, 2, 3VaR A = [1, 2, 4]; var B = A; C = B;. pop (); // remove the last element alert (B); // pop up 1, 2, 3 alert (c); // pop up 1, 2, 3 The code above shows t

Solution: So here's how we fix it: Remove the kernel's networking interface rules file so that it can be regenerated # rm -f /etc/udev/rules.d/70-persistent-net.rules Restart the VM # reboot Update your interface configuration file #vi /etc/sysconfig/network-scripts/ifcfg-eth0 Remove the macaddr entry or update it to the new macaddr for the interface (listed in this file:/etc/udev/rules. d/70-persistent-ne

Solution to NIC unavailability after Virtual Machine cloning Environment: centos6.5 Edit # vim/etc/udev/rules in the cloned VM. d/70-persistent-net.rules has two rows of records, asking the attributes of eth0 and eth1 respectively to comment out the first row, and then changing eth1 of the second row to eth0. Remember the value in attr, that is, the mac address assigned to this virtual machine # vim/etc/syscofig/network-scripts/ifcf-eth0 modify the ma

When you clone a virtual machine, you first turn off the virtual machine to record the full state of the virtual machine at this time.Virt-clone--original wyp2--name wyp3--file/data/wyp3.qcow2#克隆命令 #指定被克隆的虚拟机 #克隆后虚拟机的名称 #虚拟机文件存放路径After the new virtual machine starts, you need to change the network card configuration 3 places: Comment out the MAC and UUID, changing the IP address. Then edit a configuration file Vim/etc/udev/rules.d/70-persistent-net.rules all commented out. Note that the network

environment.The family base station can be converted to 3G ADSL or fiber-optic network bandwidth for wireless 3G message, suitable for home and office environment.The family base station is simple, based on IP protocol, the launch power is 10MW~100MW, also can provide 3G Network service while providing Wi-Fi function, compared to the low cost of traditional base station is Femtocell become the most attractive solution.A Linux boxThe Phone will automatically access the Femtocell,no user interact

that GitHub gives more than one address and can also use such an https://github.com/michaelliao/gitskills.git address. In fact, GIT supports a variety of protocols, git:// using SSH by default, but can also use https other protocols.With the https exception of slow speed, one of the biggest problems is that each push must enter a password, but in some companies that only open HTTP ports, the protocol cannot be used ssh https .SummaryTo clone a warehouse, you must first know the address of the w

objects without interfering with each other. _ Clone usage In many cases, we do not only need to clone an object, but also want the object to have its own attributes and methods. Then we need to create a _ clone method in the class. This method is similar to constructor and Destructor because it is not called directly. Take the preceding example as an example: Name = $ name; $ this-> location = $ location;} function _ clone () {$ this-> location = 'Order up';} function play () {// create meth

The object model in PHP5 invokes the object by reference, but sometimes you might want to make a copy of an object, and you want the original object to change without affecting the copy. For this purpose, PHP defines an extraordinary method, called __clone. Like __construct and __destruct, there are two underscores ahead. By default, the __clone method will establish an object that has the same properties and methods as the original object. If you want to change the default content when

1. Problem Description Cloning virtual machines in VMware is a common issue. You can directly clone virtual machines that use winows as the client. The network cannot be started after the client is cloned from a Linux virtual machine. When you run the service network start command, the following error occurs: Device eth0 does not seem to be present2. Cause Analysis Using the clone function of VMware, a new virtual machine is configured with a NIC
