[Starlingx-discuss] PCI - Passthrough Interafce on VM

[Hu, Yong]

Hi Himanshu,
If I remember correctly, this network won’t be active until is actually being used by the VMs.
So, you can go on.

In addition, the following 2 steps are important, FYI.


# create a port for PCI-Passthrough

# net-testpci is supported by “providenet-b”

openstack port create --network net-testpci --vnic-type direct-physical pt_port

# create VM by specifying the network with which the pt_port is attached.

openstack server create --flavor <flavor_name> --image <vm_image_name> --nic net-id=net-testpci pcipt_vm


regards,
Yong

Thanks Yong,

PCI Network has been created after given commands,
But In GUI it  shows as status DOWN, tried with compute lock & unlock also.

Please suggest which logs we can check.

On step #2, “--type” should be “vlan”.



On step #3, “-nt”  option was removed for a while, you might use “-c” (meaning “The class of the interface”), as follows:



$ system host-if-modify -c pci-passthrough -p providernet-b compute-0 ens513f1

Using “Horizon” is another convenient way to perform these operations.

Hi,

I built a setup with controller & compute machine. Able to spawn VM with flat network, But I need one PCI-Passthrough interface also on VM.
Please suggest the steps to create vm with PCI-Passthrough NIC.

Currently I'm following the below steps for creating pci-passthrough network:

Step1: system host-lock compute-0
step2: neutron providernet-create pci_net --type flat
step3: system host-if-modify -m 1500 -n pci_0 -p "pci_net" -nt pci-passthrough compute-0 ens513f1

step3 is giving wrong command error, can you please provide me the correct commands for the same. or if there is any other way to configure that.

Regards.
