Hey Guys,
Does anyone have any experience using OpenVSwitch with Cloudstack? Is it
actively maintained?
We are using native bridges now with KVM.
Have some scenarios where we need to accelerate the networking in our cloud.
We were thinking to pass GuestVM traffic to the NIC or vNIC (SR IOV) , but the
closest we can find to being able to that on Cloudstack was OpenVswitch.
Are you sure that OpenVSwitch will work? As far as I know the limitation
is vhost-net, a part of KVM. This struggles to go above 5Gb/s afaik.
What performance are you looking for?
I recommend you do some testing on a vanilla KVM box without CloudStack
to verify a couple of your assumptions.

But we’re not sure if features like VPC, Autoscaling, Live Migration, would
still work as those are pretty important to us.
Would using OVS also not be compatible with any future enhancements of
Cloudstack?
Regards,
Bryan
