Hello again,
this issue is related to my previous message. My goal is not only to run
VBox+Android but also some other secure applications in parallel. Therefore I
introduced a small server that multiplexes the Input and Framebuffer session so
that it is possible to switch between Android and Nitpicker based on a key
stroke. I attached a runscript to illustrate the setup.
In my setup VBox+Android are executed on one CPU and everything else runs on
another CPU. This SMP setup is necessary as otherwise Android stops booting
up. Parallel load during startup of Android seems to have some influence and
stops execution of the VM, but so far I could not identify the reason.
To the problem: Not only the performance of Android is very bad, but the whole
system feels slow and unresponsive. Applications like liquid_framebuffer are
significantly slowed down when VBox is running. This happens also when the VM
is actually in a halted state. I find it very strange that VBox running on one
CPU has such a strong impact on the performance of Apps running on another
CPU. It leaves me wondering if there is something wrong with synchronization
or the scheduler itself. Do you have any ideas or hints?
All best
Christian

# \brief Run the demo scenario with Android running in a liquid_fb.
# Virtualbox and Nitpicker+Launchpad need to run on seperate CPUs,
# otherwise Android does not boot up. For an unknown reasopn Virtualbox
# only runs on CPU 0.
