No.  If you CTRL-C the *model* - not a running process within the
model - you are effectively pulling the plug on the machine.  This is
the equivalent of you booting up and powering off your computer
without cleanly unmounting the disk, you will eventually corrupt the
disk if you keep doing it.

If you were killing the model every time, you got lucky.

Linaro images have SSHD set up already.  You have a networking setup
problem if you don't have DNS resolving hostnames, but if you have
access via IP address, you should be able to SSH into a model easily.

Try this from your host PC:

    ssh root@<ip address of model instance>

Eg,
    ssh root@192.168.1.88

More advanced networking setup information is available from ARM's
website as linked from the release notes:

http://releases.linaro.org/14.01/openembedded/aarch64/

I've never been happy with NAT networking, so I use a bridged setup.
