running multiple 'cobbler system reboot --name=xxx' at the same time, fence_cdu lists ALL reboots

[C de-Avillez]

I am running a Jenkins matrix job with four instances. Each instance will reboot the bare-metal it controls. The output of *each* fence_cdu command shows ALL systems being operated on, not only the one we are driving in this instance.

example output (from a shell script run with '-x'):

+ ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o CheckHostIP=no -i /var/lib/ubuntu-iso-testing/kernel-sru/ssh-keys/qa-ubuntu 10.189.74.2 'sudo cobbler system reboot --name=tarf'
Warning: Permanently added '10.189.74.2' (ECDSA) to the list of known hosts.
