[Bug 1325560] Re: kvm virtio netdevs lose network connectivity under "enough" load
Hi, problem seems to be solved (for me ). Problem was host could not ping guest. At the same time guest were able to ping host and the world. Downgraded qemu-kvm to previous version. That didn't help. Same problem as before. Updated to the latest release. Still same problem. Removed and recreated bridge interface. Now everything seems to be working again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325560 Title: kvm virtio netdevs lose network connectivity under "enough" load To manage notifications about this bug go to: https://bugs.launchpad.net/libvirt/+bug/1325560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1325560] Re: kvm virtio netdevs lose network connectivity under "enough" load
Hi, I have similar network connection issues (x)ubuntu xenial. Not sure when this started but coming back from holiday I noticed that connections to VM's lost from time to time. I do not have much load or anything. I have 3 VM's ( two Ubuntu 14.04 and Ubuntu 16.04). Ping will lose anywhere from 30% to 70% of the packets. Pinging other hosts has no packet loses. I have tried to change from virtio to e1000 without getting any better results. Pinging from VM to host is ok. Ping to other VM is not. My machine is quite old Asus Rampage III with Intel network chip ( product: 82567V-2 Gigabit Network Connection ). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325560 Title: kvm virtio netdevs lose network connectivity under "enough" load To manage notifications about this bug go to: https://bugs.launchpad.net/libvirt/+bug/1325560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1325560] Re: kvm virtio netdevs lose network connectivity under "enough" load
Hi Daniel, given that the old issues were either fixed (in the linked kernel bug) and the remaining ones unclear (incomplete here) it is hard to say. Given the reports I've seen over the last years I'd say this particular issue is no more present. Actually quite the opposite, if anything I've seen issues in e1000 that are easily resolved by switching to virtio. So if you face an issue I'd ask you to open up a new bug (feel free to mention this old one in there), but it certainly needs new debugging. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325560 Title: kvm virtio netdevs lose network connectivity under "enough" load To manage notifications about this bug go to: https://bugs.launchpad.net/libvirt/+bug/1325560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1325560] Re: kvm virtio netdevs lose network connectivity under enough load
I am seeing a similar issue but instead of the network breaking I get very variable latency. It's like the VM is pausing. This only happens with virtio networking. Switching to e1000 fixes the issue.
