can use the differential disk method to first install a system, then initialize and encapsulate it into a parent disk, and create n New Differential disks, in this way, you can quickly create n VMS. After talking about a bunch of basic things The following describes how to use a differential disk to quickly create a virtual machine. First, create a parent disk and install the system in it (this document uses ws2012 as an example) Install the

Java programs in the JVM and the DVM execution process:#jvm和dvm的区别 (Dalvil VM) Google just developed the android system with JVM,JVM Copyright belongs to the Sun Company is Oracle Company, later with the DVM, due to copyright issues. DVM is a 2-time development based on OPENJDK, and the DVM solves the JVM's efficiency problems, and the JVM runs less efficiently. The JVM's class code must be interpreted inside the JVM and executed inside the underlying operating system, and the actual execution i

Introduced:We talked about JVMTI's client agent earlier, and also mentioned that the agent accesses the VM through an environment pointer. Here's a look at how much the environment pointer is capable of accessing VMS.Category 1: Memory managementA.allocate. Allocating memoryJvmtierrorallocate (jvmtienv* env, jlong size, unsigned char** mem_ptr)Size: The number of bytes allocated.Mem_ptr: The first address of the allocated memory.B.deallocate.

Live Migration is also called Online Migration ). It is the process of moving a virtual machine system from one physical host to another while ensuring the normal operation of services on the virtual machine. Unlike static migration, to ensure the availability of Virtual Machine services during migration, the migration process has only a very short downtime.Currently, the mainstream dynamic migration tools www.2cto.com rely on centralized shared external storage devices such as SAN (storage area

When adding a NIC, the profile of the CP NIC is generally manual, resulting in a hwaddr mismatch. Workaround: Delete the hwaddr line in the configuration file, and use the ifconfig eth0|grep hwaddr command to view the eth0 corresponding network card mac and write it to the corresponding configuration file. Restart the NIC service network restart. Run the config command to display the ETH to correspond to the configuration file name and the name value. The/etc/udev/rules.d/70-persistent-net
