enterprise to maximize their utilization. It is to be noted that the Xen open source version does not currently support the ability to automatically migrate dynamically when a fault is DOM0 on the sensor.4. It makes it easier to add computing power to the system configuration when needed.5. You can replace the hardware as needed without interrupting the service running on that hardware.Just knowing that the benefits of dynamic migration are not enoug

1. View a configuration file for an existing virtual machine
1 The location of the virtual machine configuration file/etc/xen/test01
2 Virtual machine configuration file
2. Copy Xen virtual machine disk files
3. Copy and modify the new virtual machine configuration file
Note: It is recommended to add a virtual disk file to increase disk space by adding LVM logical volumes to the virtual machine. The creation process is as follows.
1. DD Creates a disk file
# dd If=/dev/zero bs=1024m count=4 >/data/test_01new.img
2. Turn off the test01 virtual machine
3. Modify the new virtual machine configuration file
# Modification Instructions:
# (1) name
# (2) UUID changes the last few data
With the extensive use of virtualization technology, the use of virtualization thinking and start more, such as direct expansion of disk space in this case, I recommend a new disk to add a way to fit the normal physical machine to use the way.
Another way to increase disk space is to extend the space of an existing disk directly, in this way.

I. Introduction to Xen
Xen is an open source virtual machine Monitor, developed by Cambridge University. It intends to run up to 128 fully functional operating systems on a single computer.Xen is executed on older (no virtual hardware) processors, and the operating system must be explicitly modified ("ported") to run on Xen (but provide compatibility with user a

Since the RHEL6 version, Redhat is not the original support Xen, instead of the embrace of KVM. Although KVM claims to support the full virtualization of HVM technology, KVM started late after all, far less mature than Xen technology, the system crashes often occur when running multiple instances, and certainly does not exclude the possibility that future KVM wil
The Xen virtual machine supports the installation of two types of clients. One is half virtualization, one is full virtualization. The Win2003 system requires installation and operation in a fully virtualized environment.
