Thanks a lot, guys, I still have a question: the libvirt will support the openvswitch in version 0.9.11 ( http://www.libvirt.org/news.html ) , then why Ovirt need quantum? The quantum has the openvswitch plugin too, so is it conflict or duplicate with the OVS in libvirt? Thanks, Kris On Thu, Apr

I am copy pasting a draft version of the document. It still needs work. It will eventually include information about the C and Python bindings that can be used to write to the ovsdb. *- Open vSwitch integrates smoothly with XenServer. The externally visible interface to this integ

Guru (CC'd) is actually working on a document that gives some advice on how we suggest OVS be integrated into a larger system. Guru, do you have a draft of the document that we can share with Kris and the list? Thanks, Ben. On Wed, Apr 11, 2012 at 11:31:26AM +0800, Kris zhang wrote: > Thank you

I'm sure it's possible to integrate OVS into Ovirt, since OVS works OK with many other hypervisors. The issues that you bring up haven't been a problem elsewhere; OVS integrates fine with hot migration. On Tue, Apr 10, 2012 at 11:43:06AM +0800, Kris zhang wrote: > Actually i want to integrate OVS

Actually i want to integrate OVS to Ovirt, is that possible? Also i hope it support distributed, because when one host is broken, the VMs on that host can be migrated to other host, and the network of those VMs also work well at the same time. BR, Kris On Tue, Apr 10, 2012 at 11:17 AM, Ben Pfaff

What is the network state of a physical machine that is powered off? The network state of a virtual machine that is powered off is the same. If you boot the VM again on another host, you can get the state from the hypervisor there. My answers are basically tautologies, so it seems that we are not

Hi Ben, You said that the network state is in the hypervisor, then if the host is down caused by some power issue, then how to get them? And usually the VM will be recreated on another host, but how to recovery the network information of the vm? Thanks in advanced, Kris On Mon, Apr 9, 2012 at 4:
