Proxmox VE 5.3 - 10 Gbps NIC shown by proxmox but installed VM shows 1 Gbps

[nikhilbhalwankar]

I have Proxmox VE 5.3 installed on a server JBOD. It has a FreeNAS 11.3 VM installed on it. Proxmox shows the 10 Gbps network card correctly. However, FreeNAS is showing 1 Gbps speed. Below is the output from Proxmox

dmesg | grep eth1
[    2.055154] i40e 0000:1a:00.1 eth1: NIC Link is Up, 10 Gbps Full Duplex, Flow Control: None

However FreeNAS shows 1000BaseT. I tried changing network type for FreeNAS virtual machine as per screenshot below. However, I get IP for FreeNAS VM only if I select Intel E1000. For rest others, VM does not get IP. Am I missing some setting here?

seems there is an issue with freebsd 11 if VM use q35 chipset instead i440fx.

Remember virtio is a virtual NIC not tied to the real NIC, its speed is tied to the host cpu, can be under 5 GB/s for old cpu, over 20 GB/s for beefy cpu.
of course external flow is limited to physical speed of real NIC.

Thanks for your valuable inputs. Will updating to latest version of freenas 11 help or I will have to go for freenas upgrade to higher version?
