Both virtual machine and vApp entities in your vApprun workspace can be exported as OVF packages, as shown in the following example:
> ovftool c:\My_vApprun_workspace\BigDemo c:\ovflib\
Prepend the name of the entity to export to the path. If the current directory is the vApprun workspace, you only specify the name, as shown in the following example. This example takes advantage of the fact that any source locator can be used with any destination locator. Thus, the vApp transfers directly from the vApprun workspace to the vCenter installation.
> ovftool BigDemo vi://MyvCenterServer/...
vApprun does not keep the same level of meta-data around as vSphere. Thus, the vApprun-created OVF packages will not contain any EULAs, description of properties, and such.
