Thanks Tobias, I guess I am not being clear with my question. I will give an example to hopefully be clearer. First, on a XenServer 7.1 host we disabled offload on all physical PIFS associated with that host (i.e., eth0-3). Next, on a Windows 2012 R2 Server VM and a Linux VM on that host we disabled offload on the virtual VIFs associated with those VMs. Lastly, we log on to both the Windows VM and Linux VM to disable offload using the Advanced Properties of the XenServer PV NIC in Windows and ethtool on the eth0 NIC interface in the Linux VM.
The question is this: is it necessary to log on to the VMs and disable the offload or is it enough just to disable the offload of the VIFs associated with each VM?
