Cannot change type for medium

[Chengkinhung]

Hi, I am just download latest training-labs version master and try to use with virtualbox 6.0.4 but encounter error:

Cannot change type for medium 'D:\openstack\labs\osbash\img\tmp-disk.vdi':
 the media type 'MultiAttach' can only be used on media registered
 with a machine that was created with VirtualBox 4.0 or later.

Both Linux and Windows version encounter this same error.

For windows version, I have to fix this by adding commands into labs\osbash\wbatch\create_ubuntu_cluster_node.bat just before the "VBoxManage modifyhd" command:

ECHO VBoxManage storageattach controller --storagectl SATA --port 0 --type hdd --medium %IMGDIR%\base-shared_folder-rocky-ubuntu-18.04-amd64.vdi
"%VBM%" storageattach controller --storagectl SATA --port 0 --type hdd --medium %IMGDIR%\base-shared_folder-rocky-ubuntu-18.04-amd64.vdi
ECHO VBoxManage storageattach controller --storagectl SATA --port 0 --medium emptydrive
"%VBM%" storageattach controller --storagectl SATA --port 0 --medium emptydrive

Thanks for the report. Have you tried with a 5.x VirtualBox?

I will try to reproduce the problem here.

Hi, Roger, Thanks for reply. No, I only tested the latest Virtualbox 6.0.4. I also guess this issue due to VirtualBox newly updating, but their document did not mention.
