-newvserver [ options ]
-
- Interactive utility to create vservers.
-
-Options:
- --name: Set the name of the new vserver.
- --desc: Set the description.
- --unify 1/0: Turn on unification on and off.
- --hostname: Set the host name of the new vserver
- --ip: Set the IP number(s)
- --ondev: Install the IP numbers as IP aliases on device.
- --clone: Create the vserver from another one or a distribution CD.
-
-The distribution CD are identified by special strings:
- #rh9.0m: RedHat 9 minimal
- #rh9.0f: RedHat 9 complete first CD
- #rh8.0m: RedHat 8 minimal
- #rh8.0f: RedHat 8 complete first CD
- #rh7.3m: RedHat 7.3 minimal
- #rh7.3f: RedHat 7.3 complete first CD
