I am setting up a new instance of Starwind VSAN on a 2-node Proxmox cluster. Proxmox shows the NICs and vmbr* as 10G using the ethtool command. I am using the VirtIO driver. Starwind shows the connections as 1G. What can I do to troubleshoot this?

Thank you

There's no fix and this glitch does not affec the bandwidth. You are welcome to try it with iperf.
This is a display issue with VirtIO driver and you can't fix it in Proxmox.
