1, the problem situationAfter cloning a virtual machine in VMware, the new virtual machine network can not be used, and the original operating system Nic Eth0 in the cloned new system, the network card number becomes eth1, and the IP address is lost, the network is not normal use.2. Environmental conditions

Solution: Problem 3"
1. Use ifconfig-a to view the name of the new Nic.
2. Copy the original Nic configuration file to the CD/etc/sysconfig/network-scripts/directory as the new Nic name.
3. Check the real MAC of the network adapter, CAT/etc/udev/rules. d/70-persistent-net.rules.
4. Modify the device name and hwaddr In the NIC configuration file. After adding a new IP address, restart the NIC (servicenetwork restart.
Problem 3: t
In Linux, the virtual address space for each process is independent. The virtual address space for each process starts at 0 and extends to task_size-1.In the system, the kernel allocates 1GB, while the portions available for each user-space process are 3GB.The process virtual
Windows Azure Platform Family of articles CatalogThis article describes the domestic azure China by the century connected operation Readers familiar with the Azure platform know that we are using azure virtual machine and there will be a public VM IP (VIP) and an internal IP (DIP). As follows: On the Azure platform, there are very important concepts about IP1.VIP (Virtual IP), this is the IP
The machine-level HA for the Nameserver of TFS can be done through the virtual IP mechanism. You only need a 'heartbeat' to solve the problem. The following is a simple example of the next step. ** Operating system **: 'centos 6.4 x86_64 '** Heartbeat **: ''' [root @ jdzhan1 ha. d] # rpm-q heartbeatheartbeat-3.0.4-2.el6.x86_64 ''' ----- ** Step0 **: Install Heartbeatyum installation and source code installation can be, see [previous] [1] blog. --- **
follows, and then save the settings to exit.Finally, execute the command to restart the network card for the settings to take effect.Finally, to verify that in the virtual machine ping the host, my host information is 192.168.1.100, ping 192.168.1.100, shown as shown, the configuration is successful.If you want to view the configuration information, perform the following command to viewThe CentOS configuration is successful.2) Ubuntu settings, execut
Solve the MAC address problem after migration of virtual machines. After migration of virtual machines under vmware, if the NIC cannot be started, as shown inNic startup failed, mainly because of replication. the vmdk file completely copies the Virtual Machine (including the MAC ad
Today, I helped my friend debug the Linux server of the instant messaging virtual disk. Here I will write some experiences on using the super IP update.
Log on to the Web management page of the Linux server and enter the super IP address. For example, enter 192.168.0.100.
Note that it is best to restart the server after the settings are set. Otherwise, the settings do not take effect and cannot be upda
According to the online relevant information and practical experience summarized as follows set up the Internet steps. True and effective, into the subject.To set up a virtual machine to go online1. Network adapter, virtual machine settings2. Editor, Virtual Machine Network editor->vmnet8 refer to the following settings and configure the network segment scope of

In most cases, you do not need to specify a static internal IP address (DIP) for the virtual machine. VMS in a virtual network automatically receive an internal IP address within the range you specify. In some cases, however, it is meaningful to specify a static IP address f
The official version is called "Virtual Public IP address Reservation", which we call a static extranet IP address for easy understanding.If you use the International Windows Azure service domestically, it is highly recommended that you set the IP address reservation for the virtua

1) Find the file "Virtual Machine. ini", for example, Zhai. ini.
How to find: You can view the VM storage address shown at the top of the page when running SDK manager.

In 3.17 days have written an article about the APAHCE based on the domain name, port, IP address 3 ways of virtual host implementation. The principle is the same, now record Nginx virtual host These three ways of implementation.The system version is Rhel5.6,nginx version 1.1.6.1. Domain-based:Based on the way the domain name, to first have a DNS server, here for
Most bugs describe null pointers or use other incorrect pointer values to express themselves. Such Bugs usually output a oops message.
Any address used by the processor is almost a virtual address, which is mapped to a physical address through a complex page table structure (except the physical
As long as you can find the system in the virtual machine through the IP address, you can do a lot of things, such as:ADB debugging, or using NC commands to transfer some files or folders, etc...The following is an example of debugging android-x86 in the ADB connection VirtualBox:Installing Android-x86First of all you have to install the android-x86, this is not much to say, many tutorials on the webHowever
This is a simple question that happened to be asked today, summed up here; if you do not manage through VMM there are two ways to get the IP address of the virtual machine.
The first method, of course, is easy to think of, that is, through the interface of Hyper-V Virtual Machine Manager, select the managed virtual ma
1. Virtual Address to Physical addressThe X86 chip accesses memory and requires the use of the MMU function to achieve a virtual address to a linear address to a physical address.The fragmentation mechanism of X86 is mandatory, and the paging mechanism is optional.2. Fragmen
How to add a virtual IP address (VIP) to centos 7 in Linux O M
The role of virtual ip in high availability will be discussed later. Today, let's look at how to configure a virtual IP address for the server, that is, to allocate multiple IP addresses.
① First check the IP

Note: The scope of the kernel address space is 0xc0000000 ~ 0xFFFFFFFF
