Hello all,
I'm wanting to emulate network latency + packetloss between two OVS
bridges. My first idea was to pull out a tap from each bridge and
route/forward between those two taps and add a "tc qdisc" to each tap (ex
below). Is that my best bet for what I'm trying to do?
As an addendnum, it doe

Han,
Thank you for your work. It would be useful to have this optimization as a
standard option in ovs.

The fact that you mention using VMware Workstation makes me think that
virtualization is acceptable and that you're doing this for
testing/experimentation -- and it's the non-open source aspect which is
problematic. In which case, you could install Linux (or BSD) and OVS in
VirtualBox, which h

Increase the physical NIC MTU to 1550; this will be more compatible
since the VMs will be able to use standard 1500 MTU. Be sure the
physical switches have jumbo frames enabled.

I started a port a few years ago, but never finished. Since then, support for
FreeBSD has been added to OVS. A lot of the underpinnings of OS X are based on
FreeBSD, so I suspect it wouldn't be that difficult to add it if starting from
there.

More data points.
I ran tcpdump on the host through the entire instantiation of a host and
boot up. Although somehow it appeared to get an address from the DHCP
server in the network, I saw no dhcp data. I could see arp conversations
for other hosts on the network, so I would expect it to see ever

Hi,
We just upgrade from version 1.4.6 to 2.1.2 on Xenserver, I do see greate
performance improvement.
But with 2.1.2 I can’t find the command to see current flows in the Flow Table.
With 1.4.6 I use ovs-dpctl dump-flows xapi0. Does anyone know a similar command
for 2.1.2
