Hello
I downloaded latest lxc (lxc version: 1.0.0.beta2) for android from
http://qa.linuxcontainers.org/master/current/android-armel/ and copied
files at /data of Nexus 7 Device ( ASOP 4.3 and Kernel 3.1.10). Also
added ubuntu rootfs under /data/lxc/containers
When I started the container (./run-lxc lxc-start -n ubuntu) ,
segfault happened( as shown below).
I am not sure what went wrong. It will be great if you can provide some inputs.
