In my case it's the SmartCard-Reader that's not working, i.e. the DATEV Software called "Sicherheitspaket" does not work. The background process called "SiPaHost.exe" just hangs; any client program trying to display SmartCard information does also just hang forever. That behaviour is 100% reproducible and persists over reboots of the Linux host and/or the Windows guest (Windows XP SP3). I did not try Linux guests. Yesterday, i used git to checkout all qemu-kvm versions from kernel.org and build Debian packets from it (source kept vanilla, i just applied the two patches that rename paths from 'qemuXXX' to 'kvmXXX'). The findings were: - v1.0 -> ok - v1.0.1 -> ok - v1.1.0 -> not ok - v1.1.1 -> not ok - v1.1.2 -> not ok - v1.2.0 -> not ok So far, this is consistent with the findings in this bug report. BUT: The latest HEAD from kernel.org (called "v1.2.50") also does work again! So, i'm now learning about git bisect (however, today i won't have time for this).
