Could not verify the content of 'Windows 7 x64.mf' against the available files (VERR_MANIFEST_FILE_MISMATCH). Result Code: VBOX_E_FILE_ERROR (0x80BB0004) Component: ApplianceWrap Interface: IAppliance {8398f026-4add-4474-5bc3-2f9f2140b23e}

Hi, i had the same problem with the version 3.1.4. According to a comment found here https://forums.virtualbox.org/viewtopic.php?f=5&t=26617
the system check the manifest file just if it exist. What i did was simply remove the .mf file from the directory where the .ovf and .vmdk files are and the import works fine.
This is not a solution but at least you can import your stuff.

I have converted vmx to ovf using vmware ovf tool, but when I import it in virtualbox it throws error: Failed to import appliance

The solution for this error is fixed using the below steps

VMware to Virtualbox Migration After updating my Fedora Kernel , VMware Workstation 12 stopped working. This moment I thought to switch back to Virtualbox as it has support for latest Kernels. There are pretty some good documentation on how to migrate from VMware to Virutalbox format
You can find a good document on Migration Here . In Summary the steps are Power off your guest which you are migrating Open command promt as an Adminstrator and Navigate to C:\Program Files (x86)\VMware\VMware Player\OVFTool Run ovftool
eg: ovftool "C:\Users\diaryfolio\Virtual Machines\Windows 7 x64\Windows 7 x64.vmx" C:\Users\diaryfolio\Win7Export.ovf
This would take about 15mins . So please be patient Once complete Import into your Virtualbox using "Import Appliance"
Errors that might occur
Error: "Failed to open disk” - This normally happens when the Guest VM is not properly shutdown or stopped Error while importing to Virtualbox

The quickest solution is to open it with any text/xml editor, and

1. replace word “ElementName” with word “Caption” in the whole file.
2. replace “vmware.sata.ahci” with “AHCI”
3. Then change SHA accordingly       (optional)
