xlcpupool.cfg - XL Cpupool Configuration File Syntax
/etc/xen/xlcpupoolTo 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.
A cpupool config file consists of a series of KEY=VALUE pairs.
A value VALUE is one of:
A string, surrounded by either single or double quotes.
A number, in either decimal, octal (using a 0 prefix) or hexadecimal (using an 0x prefix).
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.
The following key is mandatory for any cpupool:
Specifies the name of the cpupool. Names of cpupools existing on a single host must be unique.
The following options apply to guests of any type.
Specifies the scheduler which is used for the cpupool. Valid values for SCHED are:
the credit scheduler
the credit2 scheduler
the SEDF scheduler
The default scheduler is the one used for Pool-0 specified as boot parameter of the hypervisor.
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.
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.
