VBoxSVC locks-up badly on Windows hosts, when doing machine
lock/unlock several times and setting tracefile / CAP capture. (no
such problems on Linux hosts)
I wrote a testcase in python.
Host: Window XP, python 2.6.6 (and 2.7.1) + VBox 4.1.0 BETA1
(only workaround is it to manually kill VBoxSVC via Windows Task Manager)
1. Modify vmname in "vboxtestcase.py"
2. Run "vboxtestcase.py" several times on Win XP
This bug is *Critical*.
