It may help to configure coolkey in a Linux VM first. I am not really familiar with Windows support, David Jasa could perhaps help.

On Linux/Fedora, you can do sudo modutil -add "coolkey" -dbdir sql:/etc/pki/nssdb -libfile /usr/lib64/pkcs11/libcoolkeypk11.so.

I suppose on Windows, it should work similarly. Make sure you have permissions to modify the file too.

Btw, the path is likely  C:\Documents and Settings\All Users\Application Data\pki\nssdb. (CSIDL_COMMON_APPDATA\pki\nss)

The customer has been able to successfully do the following:

RHEL 6.7 client to RHEL 6.7 guest. Both client and guest using coolkey.
On Windows they typically use ActivClient which would be OK if the client was Windows however it is not the Guest is Windows so according to BZ 961964 they cannot use ActivClient in a guest so we recommend using coolkey. The problem is that we have no real documentation for setting up coolkey in Windows. I could not find any examples of this actually working so I am not sure if we have tested it or not.

This is the actual command they used:

C:\>"C:\Program Files\VirtViewer v2.0-128\bin\modutil.exe" -add "Coolkey" -libfi
le "C:\Windows\System32\libcoolkeypk11.dll" -dbdir "C:\ProgramData\pki\nssdb"

Frank, just to make sure, is the system they're using 64bit or 32bit? If 64bit, is coolkey 64bit as well as virt-viewer (paths suggest that this should be the case).

Could they get debug output (by setting NSPR_LOG_MODULES=all:5 before running modutil)? Can they add ActivClient dll to the database (IOW is the problem with nss/modutil or in coolkey)?

I'm afraid that we'll have to defer to NSS people here if none of suggestions above help...

The system is 64 bit and installed virt viewer is 64 bit. The coolkey files seem to only be available in 32 bit, if you look at the download page (win32).

I tried adding ActivClient to nssdb and it worked:
C:\>"C:\Program Files\VirtViewer v2.0-128\bin\modutil.exe" -dbdir %PROGRAMDATA%\pki\nssdb -add ActivClient -libfile "C:\Program Files\ActivIdentity\ActivClient\acpkcs211.dll"

nabber.org seems to redistribute RH binaries but can you be absolutely sure they're intact? We do distribute the binaries ourselves in Customer Portal, here:
https://access.redhat.com/downloads/content/216/ver=8/rhel---5/8.0/i386/product-software

CoolKey for both architectures is available there. IMO that should resolve your problem.

I'm actually suprised in two ways:
  * that 32b library wasn't installed to %WINDIR%\SysWOW64 directory
  * modutil had issues adding library to db. It didn't care about architecture
I'd expect that the module was added fine but then it would be unusable by 64b virt-viewer.

Sachin, Frank,

does this customer need card in both client and guest? If not, they could redirect whole reader using USB redirection and use ActivClient-compatible smartcard as in physical Windows 7


Frank,

Could your draw some comparisons with situation in solution to your "inverse" bug 1297533 comment 31? Does the same card work in Windows/ActivClient client and Linux/coolkey guest? If so, details about smartcard setup would be valuable to avoid compatibility issues elsewhere.

What info is required from me? I see the flag was set?

Frank

A "short" comment from SpiceQE. We also have problems with Windows guest and QEMU USB CCID: https://bugzilla.redhat.com/show_bug.cgi?id=1356656

We have IDBridge CT40 http://support.gemalto.com/?id=pc_usb_sl It is a quite popular device. It is well supported in Linux. Manufacturer provides official drivers for all Windows versions. 

We cannot get it worked in Windows guests.

https://access.redhat.com/downloads/content/216/ver=8/rhel---5/8.0/x86_64/product-downloads  provides coolkey for Windows x64 

It is not clear what drivers we should use for Windows for our tests:
* Unsupported ESC (https://bugzilla.redhat.com/show_bug.cgi?id=1356656#c4)
* Unsupported coolkey from http://www.nabber.org/projects/coolkey
* PC/SC from Gemalto.

We tried all above methods. All of them have some problems.

If we had a clear & "official" test-case we would be able to provide more logs.

What drivers we should use and how to make sure that our smartcard is passed successfully?

The real problem is that ActivClient, which is the correct tool for Windows, does not work correctly. I have moved the customer's case from this BZ to the BZ for ActivClient support.
