##### EXPECTED RESULTS

~~~

~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
It errors out on "Failed to migrate VM [VM instance {"id":116,"instanceName":"i-8-115-VM","type":"User","uuid":"5056c82d-e436-408f-b4c7-e0be8229a1cd"}] along with its volumes due to [java.lang.NullPointerException]."
Here is the log for this action: https://gist.github.com/pcfriek1987/ba7bb24a8a373e5c2abaa22e802316ec
It seems to have something to do with the template it gets assigned when migrated is my assumption, as all migrated vm's get the: kvm-default-vm-import-dummy-template or VM default import template as listed on the side.
When trying to migrate it, it says:
Copying template [212] of volume [122] from source storage pool [5] to target storage pool [3].
2024-03-24 00:28:17,788 DEBUG [o.a.c.s.i.TemplateDataFactoryImpl] (Work-Job-Executor-73:ctx-6a8adbf6 job-980/job-981 ctx-23d85860) (logid:61b73463) template 212 is not in store:2, type:Image
Template 212 is the dummy template according to MySQL.
This is kind of an issue since when migrating you cannot specify which server is should go too so instances you want to divide between physical servers you cannot move now. Instances created directly from CS work without issues.

The workaround currently is changing the vm template id in the database on the tables vm_instance and volumes.
As always, create a backup of your database before making any changes.

Looks like migrating one offline between hosts works, just not online.
