Hi Bill, Thanks for your respond. I’ve verified the speed as per advised, yes, it’s closed to 1GB-FD performance. Must be a cosmetic issue for virtio net driver from OpenvSwitch point of view.
Thanks again for sharing your experience. Best regards, .fahmie From: Campbell, Bill [mailto:[email protected]] Sent: Thursday, September 26, 2013 9:02 PM To: Shek Mohd Fahmi Abdul Latip Cc: [email protected]; Hadi Noira Omar; Shahrin Mohamad Fuzi Subject: Re: [one-users] OpenvSwitch intergration If you are using virtio as the network adapter model for your VMs then you will see the interface speed reported as 10MB interfaces (virtio has no limit, and is reported falsely in most tools). You can run a bandwidth test between 2 VMs (or from a VM to another system in your infrastructure) using a tool like iperf to validate. Here's a good blog post that gives a brief overview on how to use it: http://linux.cloudibee.com/2009/02/iperf-network-throughput-measurement-tool/ If using CentOS/RHEL, EPEL has this tool. I believe it is in the Ubuntu/Debian default repositories. ________________________________ From: "Shek Mohd Fahmi Abdul Latip" <[email protected]<mailto:[email protected]>> To: [email protected]<mailto:[email protected]> Cc: "Hadi Noira Omar" <[email protected]<mailto:[email protected]>>, "Shahrin Mohamad Fuzi" <[email protected]<mailto:[email protected]>> Sent: Thursday, September 26, 2013 6:52:15 AM Subject: [one-users] OpenvSwitch intergration Hi experts, I’m integrating OpenvSwitch with Opennebula. The good news is, they work beautifully together ☺. Bad news is very less documentation available for OpenvSwitch. Then I have doubt on the new setup of OpenvSwitch. When I deploying VM through Opennebula, it created vnet as expected. Somehow the speed of it downgraded to 10MB-FD compare what I have on physical hardware, 1GB-FD. Could someone please advise me how to ensure that vnet speed same at physical network card?
