Hi Hugo:
1. Although CentOS 6.3 does not officially support openvswitch, Using http://nullworks.wordpress.com/2012/09/19/kvm-and-openvswitch-on-centos-6-3-minimal/ as reference we tried configuring and testing ASF 4.1 cloudstack CentOS 6.3 with http://openvswitch.org/releases/openvswitch-1.7.1.tar.gz . However, since ASF 4.1 cloudstack CentOS 6.3 ships & runs with libvirt-0.9.10-21.el6.x86_64 and http://openvswitch.org/releases/openvswitch-1.7.1.tar.gz requires http://libvirt.org/sources/libvirt-0.10.1.tar.gz support, replacing libvirt-0.9.10-21.el6.x86_64 with libvirt-0.10.1.tar.gz to support openvswitch 1.7.1 resulted in advance zone SSVM failed to be created due to incompatibility of ASF 4.1 cloudstack with libvirt-0.9.10-21.el6.x86_64 2. We also tried testing with libvirt-0.9.10-21.el6.x86_64 instead of http://libvirt.org/sources/libvirt-0.10.1.tar.gz . Test failed where upon start of Openvswitch daemon , the host lost network connection completely. 3. Since cloudstack supports Ubuntu 12.04 , will attempt to test Ubuntu 12.04 KVM with openswitch Please inform if any other openswitch versions are known to work with CentOS 6.3 and Ubuntu 12.04. Thanks.
