Thanks Richard/Russell. Yes, the system went unresponsive, needed to
power-off and restart it(I ran UML from sudo account). Will create
normal user account with ulimits and check again fork-bomb. As you
mentioned it should go away :-)

Well, "control". ;-)
You can kill UML processes on the host side
Thanks for the details. I checked it by creating 5 new process (sleep
120 &) while running pstree from host. Nice, didn't know that we can
control(kill) UML process from host too.
I test ran a fork-bomb inside UML, it crashed the host. Is that
expected behavior? Is there a way to prevent this?

UML c
Hi Russ,
Thanks for the response. I tried with Slackware root file system with
same kernel, now it doesn't spawn as many child process. Its possibly
related to root file system i guess (may be something like getty
process?).
Cheers.

Hi,
When I launch single UML instance as: ./kernel64-4.3.5
ubda="cow,./CentOS6.x-AMD64-root_fs" mem=512m umid="uml"
I see quite few child process with pstree:
