[vpp-dev] virtio devices add to white list
Hi In the startup.conf , in the dpdk part we can add pci devices to the white-list . Is there option to also add virtual interfaces to white-list - I'm running VPP on virtual-machine and I have few virtio devices that I would automatically add to VPP Best Regards Avi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] virtio devices add to white list
Avi,
Yes, you can. As an example, I have it like this in my startup.conf
dpdk {
vdev virtio_user0,path=/tmp/sock0
}

Re: [vpp-dev] virtio devices add to white list
Thank you Steven
My interfaces are not vhost-user.
Just virtio interfaces created on the host and then assigned to the VM.
In my VM is see them as ens3 , ens4 etc...

Re: [vpp-dev] virtio devices add to white list
Or maybe this is impossible to acquire theses linux interfaces in the VPP.
Should I create a host-interface (af-packet) to connect this interface ?
For example to connect ens3 interface
vppctl create host-interface name ens3 ?

Re: [vpp-dev] virtio devices add to white list
Hi, Avu,
If I am understanding correctly, you want to run VPP in a VM, while the
interface is a virtio interface.
If that is the case, there is no difference as you want to use with a physical
NIC interface. You need to get the PCI address of your virtio interface by
using "lspci" + "ip" command. Or just this "basename $(readlink
/sys/class/net/ens3/device)". Once you have the pci address, put below in the
startup.conf file for VPP to consume:
dpdk {
dev {{PCI_ADDRESS_1}}
dev {{PCI_ADDRESS_2}}
uio-driver igb_uio
}
For uio-driver, you have the choice of igb_uio or vfio-pci. Up to you. If you
want igb_uio, you may need to compile it manually from dpdk if on RedHat distro.
Thanks very much!
Regards,
Yichen

Re: [vpp-dev] virtio devices add to white list
Great Yichen,
I see that the interfaces should be down before VPP startup, otherwise it does
not acquire the interface

Re: [vpp-dev] virtio devices add to white list
This is a general questions of Linux. Proper way is (1) Install the kernel
modules; (2) Create /etc/modules-load.d/.conf so KO will automatically
being loaded
More practical way, or for development:
(1) If you have a systemd managed VPP service, you can add these commands in
the systemd service file as ExecPre task;
(2) Just put this two line in /etc/rc.local.
Normally for long term, you may want to deal with kernel update case for this
particular KO.
Thanks very much!

Re: [vpp-dev] virtio devices add to white list
Why you cannot use uio_pci_generic or even better vfio-pci in no-iommu mode
instead of igb_uio?

Re: [vpp-dev] virtio devices add to white list
Thank you Yichen and Damjan
I don’t have to insmod igb_uio - VPP handles it.
So connecting to pci devices from startup config is OK.
Another question:
1. how to connect to a pci device during runtime ?
2. My VPP service is not started automatically during boot - why is that ?
Best Regards
Avi

Re: [vpp-dev] virtio devices add to white list
About the vpp service on boot - it was disabled - I enable it with systemctl
and now OK
