Hi,
I just recognized that i ahve massiv package lost problems with my newly configured proxmox host.
PVE version: 4.2-11/2c626aa1
hoster: hetzner
Kernel: Linux 4.4.8-1-pve
I just setup check_mk for my monitoring and just recognized that i have a fluctuating packet loss of 2 - 35% on my kvm vm´s.
Test VM 1: CRIT - [eth0] (up) speed unknown, in: 96.33 B/s, in-errors: 28.10%CRIT >= 0.1%, out: 344.40 B/s
Test VM 2: CRIT - [eth0] (up) speed unknown, in: 66.03 B/s, in-errors: 26.44%CRIT >= 0.1%, out: 435.34 B/s
The difference between the packetloss between the Vm´s is very small, (1-4%)
This is my network config:
traceroute:
With same config on PVE 4.0 i have no packet loss.
anyone have an Idea?
