Temporary file issues when migrating VMware VMs(VMware VM移行時の一時ファイルの問題)
I downloaded the "HPE VM Essentials Software migration guide" from the Demonstration Portal.
I tried migrating VMware VMs according to the guide.
After converting VMware VMs to managed VMs, I performed the "import as image" operation.
The data exported from vSphere was uploaded to the S3 storage that was set as storage.
When creating a new instance using that image, a vmdk image and a QCOW2 image were created in "/var/morpheus/kvm/images" on the host where the instance was deployed.
The problem is that this file remains even after the instance is deployed, and local pool capacity is consumed every time a new VM is migrated.
When creating an instance using the same image, the same file seems to be used, but a new file was not created.
Also, when creating an instance again using the same image after manually deleting the file, a new vmdk image and a QCOW2 image were created.
Ideally, the files in the above folders should be deleted automatically, but do they need to be deleted manually according to the specifications?
Or is this some kind of bug?
This could be a problem when migrating a large number of VMs.

Demonstration Portalから”HPE VM Essentilas Software migration guide”をダウンロードしました。
ガイドに従い、VMwareVMの移行を試しました。
VMware VMを管理対象VMに変換後、"イメージとしてインポート"の操作をしました。
ストレージとして設定していたS3ストレージにvSphereからエクスポートされたデータがアップロードされました。
そのイメージを使用して新しいインスタンスを作成する際には、インスタンスをデプロイしたホストの
”/var/morpheus/kvm/images”にvmdkイメージとQCOW2イメージが作成されました。
問題はこのファイルがインスタンスのデプロイ後も削除されず残り続けてしまうため、
ローカルプールの容量が新しいVMの移行のたびに消費されてしまうことです。
同じイメージを使用してインスタンスを作成する場合は、同じファイルを使用するようで新しく
ファイルは作成されませんでした。
また手動でファイルを削除後に、再度同じイメージを使用してインスタンスを作成すると
vmdkイメージとQCOW2イメージが新たに作成されました。
上記フォルダのファイルは、自動的に削除されることが理想だと思いますが、仕様的に手動で削除する必要があるのでしょうか?
それとも何かしらの不具合でしょうか?
大量のVMを移行する場合に問題になりそうです。

Re: Temporary file issues when migrating VMware VMs(VMware VM移行時の一時ファイルの問題)
Please share the output of the command below
#virsh domblklist <VM name>
This will show where the disk is pointing.
