[RFC] Creating linux bridge on Fedora and Debian based systems
by Ramon Medeiros 29 Oct '15

29 Oct '15

Hi, to create a bridge on Fedora and Debian systems, it's possible to use brctl (who work in both), but it's not persistent. So, to create a persistent bridge, files must be create in /etc/sysconfig/network-scripts on Fedora and /etc/network/interfaces on debian based. Does not exist a tool that handle this issues? If not, how kimchi are dealing when working with this differences between distros? -- Ramon Nunes Medeiros Kimchi Developer Linux Technology Center Brazil IBM Systems & Technology Group Phone : +55 19 2132 7878 ramonn(a)br.ibm.com

Issue #744
by Chandra Shehkhar Reddy Potula 29 Oct '15

29 Oct '15

Hi all, I need your input on the directory location (for debug reports and objectstore files) for new plugin gingerbase. Issue #744 is because of usage of /var/lib/kimchi directory. Kimchi uses the location /var/lib/kimchi for objectstore, isos, screenshots and so on... When I was coming up the new plugin gingerbase based on the inputs on below tickets, I tried to use same directory (/var/lib/kimchi) for the compatibility reasons. https://github.com/kimchi-project/kimchi/issues/721 https://github.com/kimchi-project/kimchi/issues/738 Now I feel that we should think about this carefully and pick the right location for objectstore and debug reports of new plugin gingerbase. I am thinking of two options here due to the fact that plugin kimchi instruction might destroy the path location /var/lib/kimchi 1. /var/lib/wok or 2. /var/lib/gingerbase Based on your inputs I will fix issue #744. Thanks and Regards Chandra
