You cannot successfully import a virtual appliance into Oracle
VirtualBox if you exported that virtual appliance from
Oracle VM as an extracted OVF that includes three separate
files, a package.ovf
file, a
package.mf
file, and a
disk.vmdk
file.
Workaround: Delete the
package.mf
file before you import the virtual
appliance into Oracle VirtualBox. Alternatively, export the
virtual appliance from Oracle VM as an OVA file.
