I was able to import one successfully, but the other two fail:
When I asked the guy who sent the VMs to me if he could verify that the OVA files are usable, he said:Failed to import appliance
Internal error (VERR_TAR_CHKSUM_MISMATCH).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Appliance
Interface: IAppliance {3059cf9e-25c7-4f0b-9fa5-3c42e441670b}
Reading the UserManual, I could not figure out how to modify the IMPORT command to do what he's suggesting.The most likely cause of this failure is that your selected data store is not configured to handle vdisks bigger than 256G, which is the default config for VMFS blocksize. If the DB import worked but the other 2 failed this is almost certainly the issue.
I have downloaded and installed those images successfully at another site so I believe the upload is good.
Any help or advice is appreciated.
