In modern data centers, virtualization technology has become a core means of achieving efficient resource utilization, flexible management, and fault isolation. XenServer, an open-source virtualization platform, provides powerful virtual machine management capabilities for enterprises. With XenServer, administrators can create and manage multiple VMs on a single piece of physical hardware. In a virtualized environment, effective management of VMs and regular backups are critical to ensure business continuity and data security. This article will focus on how to list VMs in XenServer.
XenServer is an open source virtualization platform developed by Citrix and built on the Xen Hypervisor. It virtualizes and distributes physical hardware resources (e.g., CPU, memory, storage) to multiple VMs, allowing multiple operating systems to run on a single physical server at the same time. XenServer supports a wide range of operating systems, including Windows and Linux, and provides flexible VM management capabilities. With XenServer, administrators can create, start, stop, and manage VMs, facilitating resource allocation and business isolation.
For day-to-day management, administrators often need to list all the VMs in the current environment to track their status, resource usage, and troubleshooting. xe command line tool is the core management tool provided by XenServer, which can be used to perform virtual machine management tasks including listing VMs, starting or stopping VMs, and viewing detailed configurations of VMs.
To view the VMs on a XenServer, you can use the vm-list command in the xe command line tool. This command lists all virtual machines currently on the XenServer host and provides basic information about the VM, such as name, UUID, status, CPU and memory configuration. Administrators can use this command:
xe vm-list
to get a quick overview of the current status of a virtual machine. Example:
uuid ( RO) : 8f12ac67-cd92-45d4-93bc-bda4871e4b2f name-label ( RW): VM1 power-state ( RO): running memory-static-max ( RO): 1073741824 memory-dynamic-max ( RO): 1073741824 memory-dynamic-min ( RO): 536870912 ...
This command lists all VMs by default. If the administrator needs to filter out specific VMs, some filter parameters can be used. For example:
Filter by VM name
xe vm-list name-label=<virtual machine name>
Filter by VM state
xe vm-list power-state=running
Using these filtering options, administrators can more efficiently find specific VMs or VMs in a certain state.
While virtualization technology brings ease of management and maximizes the use of resources, it also requires administrators to be more careful about data protection. If a virtual machine fails, loses data, or needs to be migrated, the recovery process will have a direct impact on the operational efficiency of the organization.
Therefore, it is crucial to back up VMs on a regular basis. Vinchin Backup & Recovery is a professional VM backup software that supports 10+ major virtualization platforms such as XenServer, VMware and Hyper-V. It provides comprehensive backup features, including incremental backup, full backup, fast recovery, automated backup schedules, and more. For XenServer users, Vinchin provides a clean and efficient way to backup virtual machines.
Creating backup tasks is very easy in Vinchin Backup & Recovery.
1.Just select VMs on the host
2.Then select backup destination
3.Select strategies
4.Finally submit the job

Q1: What if I need to check the status of a VM periodically?
A1: Consider writing scripts to automatically execute the xe vm-list and process the output accordingly. For example, utilize a cron timed task to schedule regular execution of these scripts and send reports or trigger alerts.
Q2: What other useful commands are available in the XenServer CLI?
A2: Besides vm-list, the xe commands provide many other functions such as creating a new VM (vm-install), starting/stopping VMs (vm-start, vm-shutdown), and so on. The complete set of commands can be found in the official documentation.
In conclusion, XenServer provides efficient virtual machine management in modern data centers, enabling resource optimization and business isolation. Combined with Vinchin Backup & Recovery, it ensures data security and high availability, offering a robust solution for VM management and backup.
