Hi all,
I'm Takumi Shimada.
I became interested in the rumpkernel a few days ago.
I'm trying to build the rumpkernel for xen on Ubuntu 14.04 (64bit).
The build was success. But I executed the test/hello, the error occurred as
follow:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$ sudo ./rumprun xen -i ../tests/hello/hello

!!! NOTE: rumprun is experimental and usage may change in the future
