How to Migrate VMs Seamlessly in Xen Orchestra ??
-
Hi everyone,
I am fairly new to Xen Orchestra and am exploring its capabilities for VM management. I understand it offers robust features for managing, backing up and migrating virtual machines within XCP-ng environments. However.., I am particularly interested in best practices for VM migration.
Here are some questions that I have in my mind :-
What are the prerequisites for live migration in Xen Orchestra: ??
Are there any specific configurations or network settings required for seamless migration between XCP-ng hosts: ??
How does Xen Orchestra handle storage migration? Is shared storage mandatory, or are there alternatives: ??
Have you encountered any common pitfalls or errors during VM migration, and how can I avoid them: ??I have already gone through this thread https://xcp-ng.org/forum/topic/9169/best-way-to-migrate-vms-from-old-pool-to-new-ccsp-certification it helped me alot but still need some more tips and advice. I would appreciate any tips or a step by step guide that could help streamline this process. Looking forward to learning from this community’s experience !!
Thanks in advance for your help.
With Regards,

@danieeljosee If your XCP-ng pool is set up correctly, live migration with Xen Orchestra works straight away. Compatibility is key in a pool (CPU manufacturer, CPU architecture, XCP-ng version, network cards/ports). There is a lot of leeway for CPU architecture, but I would recommend not mixing new and older CPU generations.
For the network settings, it depends on your network architecture. You can run all network traffic via one NIC or you can separate the network traffic from management, VM migration, VM and/or storage/backup using more NICs. In a homelab, one NIC is usually sufficient.
While shared storage is very helpful for VM live migration, you can also live migrate the VM with its disks attached on local storage. Just select the destination host and destination storage repository. For local storage, VMs and attached disks must of course be located on the same destination host.
