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:

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.
