Question

How to migrate VPS from one SolusVM 2 instance to another?

Answer

There is no such feature in SolusVM 2 that allows migration between two SolusVM 2 infrastructures. The existing migration feature supports transfer between CR nodes that belong to the same SolusVM 2 installation.

An improvement request has been passed to the Development Team - the ID is SIO-2863

As a workaround, apply the following scenario:

Warning: the scenario is not fully tested and not supported. Use at your risk

Note: Assume the VPS is being migrated from Master A (Compute Resource X) to Master B (Compute Resource Y)

1. Log in to the SolusVM 2 Master B admin interface
2. Create a new VPS with the same parameters as on Master A
3. Find the UUID of the needful VPS on Master A:
   

   Get Hypervisor ID of VPS in SolusVM 2 > Virtual Servers:

    
4. Log in to the Compute Resouce X via SSH
5. Find on Compute Resouce X the content of VPS that is required to migrate with the below command:
   

   # virsh domblklist <ID>
   Target    Source
   ------------------------------------------------
   sda        /var/lib/libvirt/images/388/468c2ba5ab8b70016908b774297966ef
   hdb        /usr/local/solus/iso_images/388/config.iso

   Note: replace <ID> with the actial Hypervisor ID

   Here /var/lib/libvirt/images/388/468c2ba5ab8b70016908b774297966ef - path to image file
6. Transfer the VPS data file (/var/lib/libvirt/images/388/468c2ba5ab8b70016908b774297966ef) from Compute Resouce X to Compute Resouce Y manually using SCP or rsync

Note: In case the white blank page is shown in Master B noVNC console after the migration, apply the article
