NAME

       xlcpupool.cfg - XL Cpupool Configuration File Syntax

SYNOPSIS

        /etc/xen/xlcpupool

DESCRIPTION

       To create a Cpupool with xl requires the provision of a cpupool config file.  Typically these live in
       `/etc/xen/CPUPOOL.cfg` where CPUPOOL is the name of the cpupool.

SYNTAX

       A cpupool config file consists of a series of "KEY=VALUE" pairs.

       A value "VALUE" is one of:

       "STRING"
           A string, surrounded by either single or double quotes.

       NUMBER
           A number, in either decimal, octal (using a 0 prefix) or hexadecimal (using an "0x" prefix).

       [ VALUE, VALUE, ... ]
           A list of "VALUES" of the above types. Lists are homogeneous and are not nested.

       The semantics of each "KEY" defines which form of "VALUE" is required.

OPTIONS

   Mandatory Configuration Items
       The following key is mandatory for any cpupool:

       name="NAME"
           Specifies the name of the cpupool.  Names of cpupools existing on a single host must be unique.

   Optional Configuration Items
       The following options apply to guests of any type.

       sched="SCHED"
           Specifies the scheduler which is used for the cpupool. Valid values for "SCHED" are:

           credit
               the credit scheduler

           credit2
               the credit2 scheduler

           sedf
               the SEDF scheduler

           The default scheduler is the one used for "Pool-0" specified as boot parameter of the hypervisor.

       nodes="NODES"
           Specifies the cpus of the NUMA-nodes given in "NODES" (an integer or a list of integers) to be member
           of the cpupool. The free cpus in the specified nodes are allocated in the new cpupool.

       cpus="CPUS"
           The  specified  "CPUS" are allocated in the new cpupool. All cpus must be free. Must not be specified
           together with nodes.

           If neither nodes nor cpus are specified only the first free cpu found will be allocated  in  the  new
           cpupool.
