xlcpupool.cfg(5) Xen xlcpupool.cfg(5)NAMExlcpupool.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.
FILES
/etc/xen/CPUPOOL.cfg
BUGS
This document is a work in progress and contains items which require
further documentation and which are generally incomplete (marked with
XXX). However all options are included here whether or not they are
fully documented.
