Type: infiniband
¶
Note
The infiniband
device type is supported for both containers and VMs.
It supports hotplugging only for containers, not for VMs.
LXD supports two different kinds of network types for InfiniBand devices:
physical
: Passes a physical device from the host through to the instance. The targeted device will vanish from the host and appear in the instance.sriov
: Passes a virtual function of an SR-IOV-enabled physical network device into the instance.Note
InfiniBand devices support SR-IOV, but in contrast to other SR-IOV-enabled devices, InfiniBand does not support dynamic device creation in SR-IOV mode. Therefore, you must pre-configure the number of virtual functions by configuring the corresponding kernel module.
Device options¶
infiniband
devices have the following device options:
Key: | hwaddr |
Type: | string |
Default: | randomly assigned |
Required: | no |
You can specify either the full 20-byte variant or the short 8-byte variant (which will modify only the last 8 bytes of the parent device).
Key: | name |
Type: | string |
Default: | kernel assigned |
Required: | no |
Configuration examples¶
Add a physical
infiniband
device to an instance:
lxc config device add <instance_name> <device_name> infiniband nictype=physical parent=<device>
Add an sriov
infiniband
device to an instance:
lxc config device add <instance_name> <device_name> infiniband nictype=sriov parent=<sriov_enabled_device>
See Configure devices for more information.
