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

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...
