I tried to reproduce this on a raring host I had handy and could not. The throughput definately varied, but was not consistently lopsided.
This doesn't mean it is not present in quantal, or that I didn't do something different from you. Is the vhost_net kernel module loaded? Could you please show the xml for the vms? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1079212 Title: network slow when 2 VMs using virtio net bridged to same pyhs. network device on kvm host To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1079212/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
