I assume you have sshd running on the target and that you are able to connect to it manually.  If so the problem is 
quite likely that the environment is wrong for any command Qt Creator tries to use.  To fix it you'll have to ensure 
that sshd's configuration includes:

PermitUserEnvironment yes

and then configure /root/.ssh/environment to have the appropriate environment for Qt Creator (most likely missing things
 like PATH and LD_LIBRARY_PATH).

When I ran into this a year or so ago I connected to the target using ssh and ran:

env >/root/.ssh/environment

sorry, I did not get sshd running successfully in target actually. sshd try to get key from /etc/ssh when i run sshd, 
but as you know, IFS image is read-only file system, I was not allow to run ssh-keygen to generate key in /etc/ssh by 
running ssh-keygen.

do you have any idea on it?

thanks
