I've had UML do this to me, but I doubt it's happening the same way for you.

Very early in UML development, I was having problems with processes escaping 
from syscall tracing because of bugs in the tracing thread.  When init starts 
up, it does some ioctls on /dev/console for some reason.  If it has escaped 
tracing, it will do them on the host /dev/console rather than the UML 
/dev/console.  The permissions on my /dev/console were 666, which means that 
the ioctls succeeded, and when they did, I lost the keyboard.

When I finally figured out what was happening, I tightened up the permissions, 
and the problem went away.

Having said this, I doubt that the UML init is escaping tracing, because UML 
would completely not work if that happened.  But maybe something else is 
fiddling /dev/console.
