[Kernel-packages] [Bug 1423631] Re: tap interface drops many packets on highload systems
I found the cause of the problem. The tap interface of a instance has small tx length 500 packets. At a high network load (15-25 Kpps) and high CPU load on a guest some times queue overflows and the tap interface start drop network packages. I think that queue overflow occurs in moments of micro friezes (<1000ms) of a virtual machine. I solved this problem by increasing the tx_queue up to 1. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1423631 Title: tap interface drops many packets on highload systems Status in linux package in Ubuntu: Confirmed Status in qemu package in Ubuntu: Incomplete Status in qemu-kvm package in Ubuntu: Incomplete Bug description: I use qemu-kvm in openstack.
