How to Convert OVF to OVA and Convert OVA to OVF?

OVF and OVA

Server virtualization technology makes IT environment more flexible and IT administrators can do many things to virtual machines.

VMware allows IT administrators to export the entire VM and the VM export can be saved as OVF or OVA template. Both two kinds of templates can be used to recover the data of the entire virtual machine but there are some differences.

OVF template, Open Virtualization Format, is a folder which includes VM configuration and application data. You can find files like .ovf, .vmdk, .nvram, etc. in the folder. If the aim that you export VM is to clone some applications, the most important data is vmdk file, which is the virtual hard disk. One vmdk file represents one hard drive. You can use it to attach to an existing VM.

OVA template, Open Virtual Appliance, is a zipped file and contains nearly the same data as OVF template. You can use unzip software to open it on Windows machine or use tar command to open it on Linux machine.

Why you convert OVF to OVA or convert OVA to OVF? Although they contains nearly the same data, different platforms have different requirement for VM importing. OVF and OVA files have good compatibility for importing VM on ESXi host, but on other platforms like XenServer, XCP-ng, etc. the requirements are strict. OVA template is more likely to be acceptable.

You can export OVF and OVA via OVF Tool and vCenter. If the source VM can not be used, you convert only the OVF or OVA template.

How to Convert OVF to OVA and OVA to OVF?

The tool you need to convert OVF or OVA template is OVF Tool. It is a command-line utility released by VMware. You can download it from VMware’s website.

This tool is also recommended to export and deploy OVF and OVA template because it has excellent performance in exporting and importing large file.

After installing OVF Tool, you need to remember the directory. Then you can open CMD and open OVF Tool via cd command.

The last step is converting the template via OVF Tool command. Just select the command you need.

The command to convert OVF into OVA is:

> ovftool /ovfs/my_vapp.ovf /ovfs/my_vapp.ova

The command to convert OVA into OVF is:

> ovftool /ovfs/my_vapp.ova /ovfs/my_vapp.ovf

VM template is just simple backup and you can have an advanced VM backup and migration solution.
