10GB Network in VM

[sverri]

Hallo

ich habe ein Problem mit der Netzwerkgeschwindigkeit. Hardwareseitig habe ich eine Intel X520 10GB Karte verbaut, die auch unter Porxmox läuft!
Iperf gib mir hier ca 8,9GB an.

Wenn ich eine Brigde anlege und die an eine VM anbinde bekomme ich nur werte von 255Mbit raus.
Unter Debian genauso wie unter Win10 Treiber sind alle Installiert.

Hat da einer eine Idee für mich?? Habe schon alles was ich hier finden konnte Durchprobiert.

MfG Franko

Hi!

Windows 10 ist in der VM installiert? Alle Treiber = alle Treiber nach den Proxmox VE Windows 10 best practices?
Könntest du bitte qm config VMID posten?

Hi

Aktuelle Treiber sind in VM Instaliert.

virtio NIC should be a good choice for your VMs. Could you please try to

• Create a fresh Proxmox VE VM
• Disable the firewall for it
• Update and install some iperf
• While monitoring resource usage (especially CPU usage on the client) run iperf again with this VM both as client and server

Und cat /etc/network/interfaces am Host.
