i think i notice today. i use for my homecinema a filecluster. these machines are all stand alone and have nothing directly to do with proxmox, but the master of the cluster runs on a kvm vm. actually i play a blu ray disk and see with "vnstat -l" that the master which serves the movie via sambashare with an rx of ~50Mbits and a tx ~50Mbits which seems ok. if i look simultaneously at the proxmox hostsystem "vnstat -l" shows rx of ~50Mbits and a tx of ~700Mbits until ~1000Mbits which looks strange. the problem is, that i must stop all other network activity because the move begans to hang if i dont do so. atop shows on the tap101 and tap103 which stands for the kvm vm's over 100% and sometimes over 400% in red with the same rates like above. i cant explain it.
any help?
