I confirm that running the guest on a single CPU resolv this issue. In fact hrtimer had an impact on the whole system. With a single CPU the host have now a full 100Mbits throughput.
I've seen some patch in the kernel ML dealing with the hrtimer. Will this issue be corrected in lucid ? -- after kernel message hrtimer: interrupt too slow.... the kvm guest becomes slow [possible solution found!] https://bugs.launchpad.net/bugs/503138 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
