Hello Gianluca,

Thank you for the links.

I read the documents and understood SR-IOV is supported.

This is a question apart from NFV, I need RDMA (InfiniBand) and RDMA (Ethernet) using Mellanox ConnextX-6 cards.

Do you (or does anyone) know if RDMA (InfiniBand) and RDMA (Ethernet) work on oVirt environment?

Should RDMA be used inside the VM, or on the oVirt host directly? On host level only IPoIB should work on CentOS 7 and on CentOS >= 8.4, RDMA is not supported. But it would be interesting to know if RDMA would work on a SR-IOV VF inside a VM.

I found following MLNX_OFED documentation and it seems that RDMA will work with SR-IOV.

Hello everyone,

I've checked the documentation of oVirt, but cannot find if following function can work on oVirt or not. - NFV (Network Functions Virtualization)

Does someone know NFV can work on oVirt?

For your reference, Red Hat OpenStack Platform seems to support NFV as follows

https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/...

I think you can find useful information here for RHV 4.4, that should be applicable to oVirt 4.4 too:

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/htm...

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/htm...

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/htm...

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/htm...

I don't know if it is supported to also use NFV with OVN external provider in oVirt/RHV

HIH,
