Most people do not understand the knowledge points of this "Xen virtual machine cloning method" article, so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "Xen virtual machine cloning method" article.

Xen is an open source project developed by the computer Lab of Cambridge University. Is a software layer that runs directly on computer hardware to replace the operating system. It can run multiple guest operating systems (Guest OS) concurrently on computer hardware.

Check to see if the virt-clone command exists rpm-qa | grep 'virtinst\ | libvirt'libvirt-0.8.2-29.el5_9.1libvirt-python-0.8.2-29.el5_9.1python-virtinst-0.400.3-13.el5...

# or

Which virt-clone/usr/bin/virt-clone

# if the virt-clone command is not found, you need to install libvirt and virtinst through yum

Yum install virtinst libvirt-y check the virtual machine xm list that has run on xen server.

# if we need to clone linux-node1, we need to suspend or stop linux-node1 first

Xm shutdown linux-node1
