Description of problem:
Installing the VirtIO drivers for Windows 2k12 afterwards fails.
The drivers are rejected due to an invalid catalog file.
Force-installing the drivers leads to a BSOD.


Version-Release number of selected component (if applicable):
 https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.104-1/virtio-win-0.1.104.iso
but also "virtio-win-0.1.103.iso" and "virtio-win-0.1-81.iso

How reproducible:
Every time


Steps to Reproduce:
1. Install Windows 2k12 without VirtIO
2. Add VirtIO HD afterwards
3. Mount ISO and try to install viostor.sys

Actual results:

Processing inf :            vioscsi.inf
Adding the driver package failed : The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering.

Processing inf :            viostor.inf

Expected results:
Working VirtIO-HD.


Additional info:
Using the same ISO during the initial install and installing the VirtIO drivers from the beginning works without problems. The Windows installer seems to ignore the signature mismatch that early.

Running the following command on 0.1.104 prints (among others) the
following sha1hash:
> "C:\Program Files (x86)\Windows Kits\8.1\bin\x86\signtool.exe" /verify
/v /kp E:\NetKVM\2k12\amd64\netkvm.sys
...
> Hash of file (sha1): 135E3AA23217610AEE8046F68550B0BA86F4EAE6

> "C:\Program Files (x86)\Windows Kits\8.1\bin\x86\signtool.exe" /verify
/v /kp E:\viostor\2k12\amd64\viostor.sys
...
> Hash of file (sha1): EF11F5E539EEE0A9DB6DF3710A0DAA35066C5607

Looking into the corresponding .cat "Security Catalog File"
- netkvm.cat contains the above given hash for netkvm.sys,
- viostor.cat contains 55FC4DA2EE96ECC3FD4865680436DCDA6B8C6BDD instead!

Running "sha1sum" on Linux print some completely different hashes, so I
don't know what the Microsoft tool actually hash:

> # sha1sum /cdrom/NetKVM/2k12/amd64/netkvm.sys /cdrom/viostor/2k12/amd64/viostor.sys 
> 1aa91c8e1d7680457d92c1875810a79f68af536d  /cdrom/NetKVM/2k12/amd64/netkvm.sys
> f39bc2b561091addfcac30e370227c91700d2698  /cdrom/viostor/2k12/amd64/viostor.sys
