Hi all,
I'm having a problem here with my internet connection of a VM.
iperf from the VM towards the Proxmox host IP isn't that great (since both network cards show 10Gbps for speed in ethtool) but still shows way more than a 100mbps connection:
iperf
I did manage to use "ethtool" and set the ethernet card (in Debian VM) persistent to 10000 Mbps Full duplex. But still the speed is 100mbps. I don't now what else I could do. Any help is appreciated.
Here's the requested info:
Interfaces file:
ethtool -i enp6s18
qm config 203
Thanks in advance for the suggestions and help.
