OVA conversion
If your Hypervisor doesn’t support OVA imports natively, it must be converted to a supported format.
For Microsoft Hyper-V and the VHD format, this can be done using Oracle VirtualBox using the following commands:
tar -xvf <OVA filename> *.vmdk
# Windows
VBoxManage.exe clonehd --format vhd "<filename>.vmdk" "<filename>.vhd"
# OS X / Linux
VBoxManage clonehd --format vhd "<filename>.vmdk" "<filename>.vhd"
This can also be done Using PowerShell (without VirtualBox):
