Troubleshooting / Re: Strange delay through wan interface - KVM
« on: April 06, 2015, 08:47:46 PM »
Sorry for the long answer.
I found solution, that works for me!
I changed driver in KVM from "pcnet" to "e1000" on VM options, for both NICs.
With "e1000" ping works absolutely perfect, with no delays in 24 hours (i keep ping working for 24 hours).
It was with http load test, so i think, problem solved.
I'll remind, it's 1.4.1 version.
I also tried driver "virtio", it's special driver for virtualized NICs.
With this driver ping works, but http answers didn't pass through wanos-wanos.
virtio is a specific driver, it's not emulate many physical things, like carrier speed and so on.
It's something like standart driver for VM in KVM/xen.
So, if you will had a free time, i recommend try to make this driver working.
Thanks for the link "Wanos throughput on KVM", i missed it when first read your answer.
