[junxiawang]

I rerun the testcase but could not reproduce ,and I will add debug information to get the root cause for this case failed.

@caomengmeng please take a look and see if it should be closed

@junxiawang , we need to put effort to make your three cases (nodeset_shell ,nodeset_cmdline and nodeset_runimg) stably and reliably.

Not matter these cases is successful or failed, the error message listed by @caomengmeng above will always flash the log of auto test. You can't just rerun the cases in your own development environment, we need to face these error.

I think there are coding problem in your file genesistest.pl. I tried to read your code, it is very hard to debug. I really don't recommend to call function like your below way

  115     if (&testxdsh(&rungenesiscmd(&get_arch))) {

There is not way to debug if there is something goes wrong.

So please refine these cases in 2.13.4 sprint 1 by asking help from @zet809 . thanks.
