Puppet Class: vswitch::dpdk
- Defined in:
- manifests/dpdk.pp
Overview
Configure OVS to use DPDK
Parameters
- memory_channels
-
(optional) The number of memory channels to use as an integer.
- host_core_list
-
(optional) The list of cores to be used by the lcore threads. The host_core_list is a string with format as <c1>[,c3,…] where c1, c2, etc are core indexes between 0 and 128. For example, to configure 3 cores the value should be “0-2”
- package_ensure
-
(Optional) State of the openvswitch package Defaults to ‘present’.
- pmd_core_list
-
(optional) The list of cores to be used by the DPDK PMD threads. The pmd_core_list is a string with format as <c1>[,c3,…] where c1, c2, etc are core indexes between 0 and 128 For example, to configure 3 cores the value should be “0-2”
- socket_mem
-
(Optional) Set the memory to be allocated on each socket The socket_mem is a string with comma separated memory list in MB in the order of socket numbers. For example, to allocate memory of 1GB for socket 1 and no allocation for socket 0, the value should be “0,1024” Defaults to undef.
- socket_limit
-
(Optional) Limits the maximum amount of memory that can be used from the hugepage pool, on a per-socket basis. Defaults to undef.
- enable_hw_offload
-
(optional) Configure OVS to use Hardware Offload. This feature is supported from ovs 2.8.0. Defaults to false.
- disable_emc
-
(optional) Configure OVS to disable EMC. Defaults to false
- vlan_limit
-
(optional) Number of vlan layers allowed. Default to undef
- revalidator_cores
-
(Optional) Number of cores to be used for OVS Revalidator threads.
- handler_cores
-
(Optional) Number of cores to be used for OVS handler threads.
- enable_tso
-
(Optional) Enable TSO support. Defaults to false.
- vhost_postcopy_support
-
(Optional) Allow switching live migration of VM attached to dpdkvhostuserclient port to post-copy mode. Defaults to false
- pmd_auto_lb
-
(Optional) Configures PMD Auto Load Balancing Defaults to false.
- pmd_auto_lb_rebal_interval
-
(Optional) The minimum time (in minutes) 2 consecutive PMD Auto Load Balancing iterations. Defaults to undef.
- pmd_auto_lb_load_threshold
-
(Optional) Specifies the minimum PMD thread load threshold of any non-isolated PMD threads when a PMD Auto Load Balance may be triggered. Defaults to undef.
- pmd_auto_lb_improvement_threshold
-
(Optional) Specifies the minimum evaluated % improvement in load distribution across the non-isolated PMD threads that will allow a PMD Auto Load Balance to occur. Defaults to undef.
- vs_config
-
(optional) allow configuration of arbitrary vswitch configurations. The value is an hash of vs_config resources. Example: { ‘other_config:foo’ => { value => ‘baa’ } } NOTE: that the configuration MUST NOT be already handled by this module or Puppet catalog compilation will fail with duplicate resources.
- skip_restart
-
(optional) Skip restarting the service even when updating some options which require service restart. Setting this parameter to true avoids immedicate network distuption caused by restarting the ovs daemon. Defaults to false.
