[ovs-dev] [PATCH v2 0/3] Support for OVS datapath on Windows platform.

I have disabled the RX/TX checksum offload on both HyperV and VM's (also tried with a KVM).

The pings work but they are not encapsulated using VXLAN.

Kind Regards,
Alin.

I am assuming you have disabled RX/TX checksum on both the HyperV¹s and
the VM¹s. So, do the pings work now? You mentioned that (02) and (03)
works, but the comment above seems to suggest that something is still not
working.
