ESXi 6.7 OVA Import Problem

Hi,

I am trying to install a custom xubuntu ova to esxi 6.7 but I am getting an error with different browsers. Error says;

Unknown error

There was an error creating the import specification from the OVF file.

Failed to deploy VM: [missing message value]

In the meanwhile vmkernel.log says;

When I checked NIC settings WOL really looks like disabled but this VM has no relation with these interfaces. Also a core file occures each time I try to import the file under /var/core. 

Same ova file works in VirtualBox without any problem. Any help is appreciated.

Thanks
