CS 4.20.1 : SR-IOV Passthrough PVI vNIC MAP to a VM interface

[tatay188]

The required feature described as a wish

We Just migrated to CS 4.20.1 As an Operator we need to be able to Map the vNIC to a VM interface - similar to VMWARE and OPEN-NEBULA

We loaded the PCI modules on the KVM agent, but there is no UI to take advantage of the PCI-vNIC, using regular linux bridges, VXLAN-guest and VLAN-Public, no DPDK.

Where we currently we are migrating VMWARE and opennebula VNF functions.

Does Cloudstack have at least a manual process to achieve this on cloudstack? No matter how old. or a Script that we Should activate?

expecting Something similar to OpenNebula:

**To use PCI passthrough in OpenNebula, the devices first has to be listed. OpenNebula is using host monitor to collect the available devices. This monitor is a script that is run regularly by OpenNebula on each host. It is located at:

/var/lib/one/remotes/im/kvm-probes.d/pci.rb

and it is configured with a configuration file at:

/var/lib/one/remotes/etc/im/kvm-probes.d/pci.conf

In this configuration, you can define which devices will be listed in OpenNebula as available for PCI passthrough. You can select devices based on PCI Id, PCI address or PCI device name. Example of configuration selecting Mellanox ConnectX-5 Virtual Functions:

:filter: '15b3:1018'
:short_address: []
:device_name: []**

Thank you

@tatay188 you should be able to implement PCI passthrough with agent hooks feature [1] or extraconfig [2]
