Can you explain how the initscript makes it really hard to use the package without the DKMS module? The packaging is oriented toward using the kernel modules supplied with the packages, but we do not intentionally make it difficult to use the integrated upstream module. > Moreover, the brcompat module does not seem to work together with > the kernel module upstream (i.e. not the DKMS module from your > source package). Is there a way to get these working together? No. From the FAQ available at http://openvswitch.org/faq/: Q: What features are not available in the Open vSwitch kernel datapath that ships as part of the upstream Linux kernel? A: The kernel module in upstream Linux 3.3 and later does not include the following features: - Bridge compatibility, that is, support for the ovs-brcompatd daemon that (if you enable it) lets "brctl" and other Linux bridge tools transparently work with Open vSwitch instead. We do not expect bridge compatibility to ever be available in upstream Linux. If you need bridge compatibility, use the kernel module from the Open vSwitch distribution instead of the upstream Linux kernel module. - Tunnel virtual ports, that is, interfaces with type "gre", "ipsec_gre", "capwap". It is possible to create tunnels in Linux and attach them to Open vSwitch as system devices. However, they cannot be dynamically created through the OVSDB protocol or set the tunnel ids as a flow action. Work is in progress in adding these features to the upstream Linux version of the Open vSwitch kernel module. For now, if you need these features, use the kernel module from the Open vSwitch distribution instead of the upstream Linux kernel module. - Patch virtual ports, that is, interfaces with type "patch". You can use Linux "veth" devices as a substitute. We don't have any plans to add patch ports upstream. > For Post-Wheezy this may become more critical as you may want to > stop shipping the DKMS/kernel module source at some point. Yes, that would be nice. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
