- --context ... the static context of the vserver [default: none; one will
- be generated for you]

- --hostname <hostname>
- --netdev <device>
- --netbcast <broadcast>
- --netmask <netmask>|--netprefix <prefixlen>
- ... sets the default netmask (a.b.c.d quadruple) or prefixlen
- (length of the interface)
- --interface [<name-suffix>=][<device>:]<ip>[/<mask|prefixlen>]
- ... declares an network-interface; this option can be specified
- multiple times
- --flags <flags>+
- ... sets comma-separated list of flags; possible flags are
- lock: Prevent the vserver from setting new security context
- sched: Merge scheduler priority of all processes in the
- vserver so that it acts a like a single
- one (kernel 2.4 only).
- nproc: Limit the number of processes in the vserver
- according to ulimit (instead of a per user limit,
- this becomes a per vserver limit)
- private: No other process can join this security context.
- Even root
- --cpuset <name>
- ... declares the CPUSET this vserver will run in [default: none]
- --cpusetcpus <number[-number][:<exclusive>]>
- ... sets which cpus belong to the CPUSET,
- exclusive is a flag (0|1) prohibiting any other cpuset from
- using those cpus
- --cpusetmems <number[-number][:<exclusive>]>
- ... sets which memory pools belong to the CPUSET,
- exclusive is a flag (0|1) prohibiting any other cpuset from
- using those memory pools
- --cpusetvirt
- ... virtualize cpuset (guest will see only CPUs defined in cpuset)
- Requires kernel patch from http://www.bullopensource.org/cpuset/
- --initstyle <style>
- ... configures the initstyle (e.g. minit,sysv,plain)
