    Packet loss on VMs, but not with Proxmox directly

    I just installed Proxmox on my Intel NUC with N100. I was noticing a terrible performance on accessing some VMs remotely by HTTP protocol, however everything looks great accessing Promox (Proxmox has 0% of packet loss). So I tested the ping and packet loss from my VM IPs and to my surprise...
