Just in case this helps anyone else- I wasted a lot of time on this one this morning. I appreciate ovftools is a VMWare product...
I was trying to convert an exported ovf vm folder to .ova as a single file for import into AHV.
I was just getting a generic error- file "" could not be opened:
trying to test or verify I got similar:
c:\Program Files\VMware\VMware OVF Tool>ovftool --verifyOnly --machineOutput V:\Grid-lic-server\Grid-lic-server.vmx
ERROR
+ <Errors>
+ <Error>
+ <Type>ovftool.io.file.open</Type>
+ <LocalizedMsg>
+ Failed to open file: V:\Grid-lic-server\Grid-lic-server.vmx
+ </LocalizedMsg>
+ <Arg>
+ V:\Grid-lic-server\Grid-lic-server.vmx
+ </Arg>
+ </Error>
+ </Errors>
RESULT
+ ERROR
Not very illuminating.
I tried setting a log output and for next to nothing useful even in verbose mode:
However:
When I navigated to the local directory and ran the same export / convert command where the .vmx file was located I got:
C:\Program Files\VMware\VMware OVF Tool>ovftool D:\Grid-lic-server\Grid-lic-server.vmx D:\ova\grid-lic-server.ova
Opening VMX source: D:\Grid-lic-server\Grid-lic-server.vmx
Error: File (D:\Grid-lic-server\/vmfs/volumes/54de0796-0c4fc176-6dc6-c4346ba9686c/installers&isos/microsoft_images/windows_server_2012_R2_vol_lic/SW_DVD9_Windows_Svr_Std_and_DataCtr_2012_R2_64Bit_English_-3_MLF_X19-53588.ISO) could not be found.
Completed with errors
Now this is a bit more like it! : I can see I had an image file attached that ovftool now cant find.
I simply opened it up in player, removed the CD volume in settings and then saved it.
I then reran the command and it wrote out the single .ova file as I expected.
Hope this helps someone else.
