Slow Internet in the VM

[justt3ch]

Hello all,

Am facing some difficulty on configuring my VM ?
the internet connection is very slow to point it shows 0 Mbit/s

speedtest-cli

but on the other hand LXC shows a speed of 300 Mbit/s

That indeed is really slow. Can you run iperf3 from your VM to the PVE host it is running on? What are the results? So

# on the PVE host
iperf3 -s

# in the VM
iperf3 -c <PVE_IP>

Hello
I tried it but it gives an error
from VM to host >> error - unable to connect to server: Connection refused

Note: I still can ping the host


I tried iperf3 from other lcx I have
