yes, i've used the same virtual machines in both cases. everything is the same except the driver. I switch from virtio to e1000
glance image-update --property hw_vif_model=e1000 <image-id> Now I relaunch the virtual cluster and everything works perfectly fine. I've tested with 5 times the load but it doesnt crash anymore. I have tested the same cluster configuration with virtio on Centos 6.5 kernel 2.6.32-431.17.1.el6.x86_64 #1 SMP Wed May 7 23:32:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux and that crashes too. I will test the centos version with e1000 and see if that works. -- 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 vm loses 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
