For KVM VPS

The following should be performed to manually migrate KVM VPS from one node to another:

1. Stop the required VPS in SolusVM > Virtual Servers > VPS > Shutdown. Note VMID of VPS, for example, it is kvm101

2. Connect to the source slave node over SSH.

3. Find a logical volume of the VPS:

   # lvdisplay | grep "LV Path" | grep "kvm101"
   LV Path /dev/yourvg/kvm101_img
   

4. Create a copy of the logical volume:

   # dd if=/dev/yourvg/kvm101_img | gzip | dd of=/home/kvm101_backup.gz bs=4096
   

5. Transfer the copy to the target slave node, for example using the following command on the source node:

   # scp -C /home/kvm101_backup.gz root@targetserverip:/home/
   

6. Connect to the target server over SSH.

7. Create a logical volume with the same size and name:

   # lvcreate -n kvm101_img --size 10G /dev/yourvg
   

8. Restore the copy to the created logical volume:

   # dd if=/home/kvm101_backup.gz | gzip -d | dd of=/dev/yourvg/kvm101_img bs=4096
   

9. Connect to your Master node over SSH

10. Update Master node database with the new location of VPS

    # /scripts/vm-migrate ID NEWNODEID
    

    Where ID - ID of the migrated VPS, can be seen in column ID inSolusVM > Virtual Servers; NEWNODEID - ID of the target node, canbe seen in SolusVM > Nodes.
    For example:

    # /scripts/vm-migrate 20 5
    

    11. Reboot VPS via SolusVM > Virtual Server > migrated VPS > Reboot for changes to take effect and verify that it is working.

11. After verifying correct work of VPS - remove logical volume and the VPS directory on the source server:

    # lvremove /dev/yourvg/kvm101_img
    # rm -rf /home/kvm/kvm101/
