Hi Stefan, do you have upgraded kernel ?
maybe it could be related to vhost-net module too. ----- Mail original ----- De: "Stefan Priebe, Profihost AG" <s.pri...@profihost.ag> À: "qemu-devel" <qemu-devel@nongnu.org> Envoyé: Mercredi 14 Décembre 2016 16:04:08 Objet: [Qemu-devel] any known virtio-net regressions in Qemu 2.7? Hello, after upgrading a cluster OS, Qemu, ... i'm experiencing slow and volatile network speeds inside my VMs. Currently I've no idea what causes this but it's related to the host upgrades. Before i was running Qemu 2.6.2. I'm using virtio for the network cards. Greets, Stefan
