    Does VMA support  SR-IOV?



      I am trying VMA in a Linux kvm Virtual Machine, with SR-IOV, MLNX_OFED_LINUX-2.0-3.0.0 and fw 2.30.3000

      I have log_num_mgm_entry_size=-1 in modprobe but it doesn't seem to matter, because the value in /sys/module/mlx4_core/parameters/log_num_mgm_entry_size is always 10 (the default one). In hypervisor the /sys param is -1.


      Also, what does the Error about QP mean?

      UDP seems to be working but vma_stats does not show any offloaded packets.

      TCP doesn't work at all, the client fails to connect to the server.

      BTW, on bare metal VMA works quite nice.
