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

Some example soft lockup messages with call traces and on without a
call trace are attached below. For some reason not all messages
include a call trace.
