If you’re getting this error, your boot media is corrupt or the medium you used to transfer the image is faulty.
‘Error Loading /s.v00
Fatal error: 6 (Buffer too small)’
I received this error after attempting to load an ESXi Open Virtual Format (.ova) onto my home lab server over wireless. The problem was not the wireless, it was a bad cable coming from my router to my main ESXi server.
After replacing this cable, retransfering/importing the ova it worked without any issues. Researching this error will show you many similar results, however it comes down to a corrupt source file or boot media.
