Package: virtualbox-ose Version: 3.2.10-dfsg-1 Severity: important
Hosting VirtualBox VMs on this machine often results in scheduling issues for user processes, and sometimes the machine becomes unresponsible for a long time, after which a message about soft lockup is found in system log. The system is running stock Debian kernel and VirtualBox. The system still reacts to external inputs. For example, when running the ping script below, and seeing that it has been stuck in sleep() for a few seconds, hitting a key on keyboard of the machine immediately ends the sleep. It appears as if the kernel fails to set a timer interrupt to wake itself up for some reason. The scheduling issues manifest easily as sleep() taking varying periods of time. Below is output of a Python script that attempts to ping some of the VMs and then sleep(1-ping_duration) seconds. Pings took 0.0038001537323 Trying to sleep 0.996199846268 Sleep took 1.77373981476 Pings took 0.00364708900452 Trying to sleep 0.996352910995 Sleep took 8.63721585274 Pings took 0.00382900238037 Trying to sleep 0.99617099762 Sleep took 5.65230202675 Pings took 0.00357413291931 Trying to sleep 0.996425867081 Sleep took 1.42871999741 Some example soft lockup messages with call traces and on without a call trace are attached below.
