After rebooting XEN host, odd processes have appeared...

After I rebooted my XEN linode last light,

I am seeing a lot more processes running that before:

Are these related to a service update?

The only ones that are Xen related are xenbus and xenwatch. The rest were there in UML, and in most physical installs, too.

Some of them are multiplied by the number of CPU cores. In UML there was only 1 – in Xen you have 4.

Use a different 'top' like htop and it'll filter out those kernel processes.

Now that is just too cool for school. Thanks for the tip! I JUST NOW got my SMP parallel python code running and saw your post - htop is perfect for monitoring my Parallel Python tests.

In case anyone wants to see my public domain code for parallel genetic algorithms in Python:
