Ok i finally got the virtio_net driver to run on my xpenology VM. I missed that you also need to load the vfio_pci driver. For anyone who wants to try that out as well: you need to append the following to rc.modules EXTRA_MODULES variable: virtio virtio_ring virtio_pci virtio_net and then rebuild the extra.lzma file. I now get around 20 GBit/s between my Xpenology VM and Proxmox Hypervisor using iperf3 Which is fantastic since I now don't need to pass through my 10G NIC to the Xpenology VM any longer and instead can use the 10G NIC for the Proxmox Host. And the networking between the Xpenology VM and the Proxmox Host won't be a bottleneck.

Did anyone have any luck getting virtio_net driver running with Xpenology under Proxmox? I grabbed the virtio.ko, virtio_ring.ko and virtio_net.ko modules from the extra.lzma and loaded them manually with insmod on the shell. The modules load fine without errors, but the driver doesn't probe any virtio PCI device. I tried both a DS3617XS (DSM 25423 Loader 1.03b) and DS918+ (DSM 25426 Loader 1.04b) installation. As an alternative I tried vmxnet3 (also on both installations). This driver probes the NIC correctly, but strangely no traffic is coming through to the host Edit: ok vmxnet3 strangely works if I add is as a secondary NIC in proxmox. But performance of vmxnet3 is really bad (not related to xpenology, that's also the case on a normal Linux VM.. with vmxnet3 I get about 7-8 GBIt/s where it's easily possible to get 30Gbit/s with virtio_net), so it would still be great to get virtio_net to work on Xpenology.
