> CloudStack volumes and templates are one single virtual disk in case of
> XenServer/XCP and KVM hypervisors since the files used for templates and
> volumes are virtual disks (VHD, QCOW2). However, VMware volumes and templates
> are in OVA format, which are archives that can contain a complete VM
> including multiple VMDKs and other files such as ISOs. And currently,
> Cloudstack only supports Template creation based on OVA files containing a
> single disk. If a user creates a template from a OVA file containing more
> than 1 disk and launches an instance using this template, only the first disk
> is attached to the new instance and other disks are ignored.
> Similarly with uploaded volumes, attaching an uploaded volume that contains
> multiple disks to a VM will result in only one VMDK to being attached to the
> VM.
> This behavior needs to be improved in VMWare to support OVA files with
> multiple disks for both uploaded volumes and templates. i.e. If a user
> creates a template from a OVA file containing more than 1 disk and launches
> an instance using this template, the first disk should be attached to the new
> instance as the ROOT disk and volumes should be created based on other VMDK
> disks in the OVA file and should be attached to the instance.
