Hey,
Here's a bunch of patches attempting to improve the performance
of virtio_net. This is more an RFC rather than a patch submission
since, as can be seen below, not all patches actually improve the
perfomance measurably.
I'm still seeing the same problem I saw with my patch series.
Namely, dhclient fails to get a DHCP address. Rusty noticed that RX
has a lot more packets received then it should so we're suspicious
that we're getting packet corruption.
I have been discussing this (on this list) in another thread. Putting
tcpdump on the eth0 device in the VM, the br0 device in the host, and
the eth0 (physical NIC) in the host, you can see that when the VM
generates a DHCP request it shows up on the br0 in the host, but never
gets sent on the wire by eth0.
That's the point of failure, at least using RHEL5/FC6/kvm-66 as the
environment.
Does playing with the bridge forward delay ('brctl setfd') help?
