> Short background: for over a year I have used kvm to run a Windows XP
> Professional 32bit SP2 install with the EnCase software package, which
> requires an Aladdin HASP USB dongle. The last working installation
> used Debian unstable's kvm-72 and qemu 0.10.5 packages, together with
> linux 2.6.29.4 (and Win XP 32 bit SP2, EnCase 6.13 (I have prevoiusly
> also successfully used EnCase 4.22a with an older Aladdin HASP USB
> dongle)). In an attempt to increase disk performance I upgraded to
> kvm-87, and then my problems began.

> Running kvm-87 works fine up until the point when the Aladdin HASP
> driver wants to talk to the dongle. For example, I did one test run
> with a clean Windows install where I installed EnCase 6.13 and the
> dongle drivers, started up EnCase in Acquisition Mode, acquired the
> running virtual hard disk while playing Solitaire (to keep both disk
> and graphics going), and it went fine. Then, when I enter "usb_add
> host:0529:0001" in the qemu monitor it takes somewhere between a few
> seconds up to a minute or two before kvm crashes and dumps core.

http://www.linux-kvm.org/page/Bugs ;
> -no-kvm-irqchip and -no-kvm-pit only slows the system down, it still crashes.
> -no-kvm crashes on startup (see the attached file crash3.txt).

> All these test runs make me guess that the problem lies somewhere in
> kvm's USB code, and is triggered by the Aladdin HASP drivers, unless
> there is something fundamentally wrong with my install (the immediate
> crash with -no-kvm might indicate that). I can however see nothing
> obviously wrong with my install and therefore suspect kvm.

> Three files, describing three different test runs (including gdb
> backtraces) which all crash at some point, are attached to this mail.
> They are generated on a Fujitsu Siemens Celsius workstation with an
> "Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz" (according to /proc/cpuinfo),
> 4GB RAM, running Linux 2.6.30 x86_64, and kvm-87 and qemu-kvm-0.10.5

http://www.linux-kvm.org/page/Downloads . No Debian kvm or qemu

> The exact same problems also show up when running the same kvm/qemu
> versions and the same virtualized versions (of Win and EnCase), and on
> both Linux 2.6.29.4 and 2.6.30, on a HP ProLiant DL380 G5 with 12GB
> RAM and an Intel Xeon 5160 (don't know if it's a quad core or two dual
> cores; in any case, it's four cores total). That is the intended
> production system, and the system on which I have successfully been
> running Windows and EnCase on older kvm versions (kvm-72 is working, I
> don't remember if I've used any version before that).
