If for some reason SolusVM automated migration is failing or if you just want make your hands dirty and wants to manually migrate a KVM VPS to another VPS Node, just follow these simple steps:
Run following commands on Source VPS Node:
Assuming your KVM ID for your VPS is “kvm5368”
# lvdisplay | grep kvm5368
LV Path /dev/vg_node10/kvm5368_img
LV Name kvm5368_img
Now lets shutdown the Source VPS:
# virsh shutdown kvm5368
Now once it’s shutdown lets create an image of the VPS Disk:
#dd if=/dev/vg_node10/kvm5368_img | gzip | dd of=/root/kvm5368_backup.gz bs=4096
Now lets create a Logical Volume on the destination node, so run following commands on the destination node:
# lvcreate -n kvm5368_img –size 30G /dev/vg_node
Now transfer the VPS image file created earlier from source to destination node:
# scp -C /root/kvm454_backup.gz root@destinationvpsnode:/root/
Once it’s transferred then run following command on destination vps node to restore the VPS Image:
dd if=/root/kvm5368_backup.gz | gzip -d | dd of=/dev/vg_node/kvm5368_img bs=4096
Once it’s restored run following command on your SolusVM Master:
/scripts/vm-migrate <vserverid> <newnodeid>
Now you should be able to boot the new migrated VM from SolusVM
