RoCEv2 with SR-IOV on Azure


Is it possible to enable RoCEv2 on a VM accelerated networking enabled on Azure?
It seems that “ConnectX-4 Lx Virtual Function” is provided by the accelerated network.

$ lspci
29aa:00:02.0 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx Virtual Function] (rev 80)

OS is RHEL 8.
Let me know if I can give you any other information.


The VF should support RoCEv2.
use below command to current RoCE mode
#cma_roce_mode -d -p

modify RoCE mode
#cma_roce_mode -d -p -m <1|2>
