Hello, I am not sure about the second bug, sorry, but the warnings in your first output would not affect your simulations, unless you are planning to something using those.
"Mount failed for selinuxfs on /sys/fs/selinux: No such file or directory" selinux in Ubuntu has some problems: https://wiki.ubuntu.com/SELinux . I wouldn't worry about this warning since it won't affect your simulations. "init: plymouth-upstart-bridge main process (x) terminated with status y" Quoting http://upstart.ubuntu.com/cookbook/#plymouth-upstart-bridge-ubuntu-specific "The plymouth-upstart-bridge is an Ubuntu-specific facility to allow Plymouth to display Upstart state changes on the boot splash screen." For more info: https://wiki.ubuntu.com/Plymouth Removing /etc/init/plymouth-upstart-bridge.conf prevents these warnings. I was getting similar warnings and have not had any problems since. "init: ureadahead main process (951) terminated with status 5" This one is a long lasting bug in Ubuntu: https://bugs.launchpad.net/ubuntu/+source/ureadahead/+bug/523484 Despite these warnings, you should be able to start your simulation with your first command. Did you get any other warnings/errors?
