What happen when you run it in the default console you are working?

One thing is that UML uses uml_net to setup the tuntap interfaces. It is a
setuid program. Now gdb does not get the setuid priviledges so the tuntap

I am using as part of the command line command line:
ssl2=tty:/dev/ttyS0
and I am giving ttyS0 on the host permission to be read-write by others so
that the UML can open it.
Also on inittab I have the line:

'CONFIG_KERNEL_STACK_ORDER' is a UML configuration option to set the size

I think your kenel is not configured for UML. Make sure it has a .config for
