The good news is, they work beautifully together <span face="Wingdings" data-mce-style="font-family: Wingdings;" style="font-family: Wingdings;">J</span>. 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?
