nova-api doesn't run, IllegalFlagValue in log files

[Tobbe]

When installing a comment was generated in nova.conf on the --multi_host=True line. That comment cases a stack trace to be printed in the nova logs, and nova-api does not stay running. (It prints a pid, but then it exits/crashes). Removing the comment seems to fix it.

This is the log output:

With this setting, every nova-compute node also needs nova-network.: ('Non-boolean argument to boolean flag', 'True # Use multiple nova-network nodes.
