Re: [Xen-users] Query - Issue creating VMs when not using bridge that Xen created, but using ovswitch.

Thanks Simon. Yes I have done like what you said (commented out (network-script network-bridge) , but not vif-bridge), and that makes sense as well because I need to configure virtual interfaces.

And, I just relplaced one line in xen-network-common.sh
 brctl addif ${bridge} ${dev}
 ovs-vsctl add-port ${bridge} ${dev}

And, I am able to connect virtual interfaces with new bridge eth0 (created manually by me by ovs-vsctl). Everything works fine :) :)

But QoS controls by ovs tools are not being reflected in the connection to VMs :( I set maximum ingress rate of 1Mbps, but still I get 90Mbps in Netperf test.

Also,I want to put it in a script, which should run before xen scripts at the boot time, (run level 3 & 5, right? And why twice ?). Where should I put up the my script, and how do I make sure it runs before Xen scripts. Also, I put up few echo statements in xen script file, where do i see the print? which log file?

Thanks & Regards

Xen has replaced eth0 with peth0, and has created a bridge named eth0. And eth0 is connected peth0 interface , vif2.0 interface (VM), and everything is working fine. Now I delete the VM.

Now, for OVS, I have deleted the bridge eth0, I have created an ovs bridge named br0 using ovs-vsctl and connected it with peth0.
I comment the lines for network bridging & vif bridging.
#(network-script network-bridge)
#(vif-script vif-bridge)
And restart the xend.

You will need a vif-script defined - and unless you find someone who's already done one, then you'll have to write it yourself. "network-script" is deprecated in favour of using host OS tools - so you are correct to comment that out.

But "vif-script" will be needed - and it will need to do whatever is required to create a VIF and connect it to the right virtual switch.
