What does your oVirt development environment look like?
by Adam Litke 25 Aug '14

25 Aug '14

Ever since starting to work on oVirt around 3 years ago I've been striving for the perfect development and test environment. I was inspired by Yaniv's recent deep dive on Foreman integration and thought I'd ask people to share their setups and any tips and tricks so we can all become better, more efficient developers. My setup consists of my main work laptop and two mini-Dell servers. I run the engine on my laptop and I serve NFS and iSCSI (using targetcli) from this system as well. I use the ethernet port on the laptop to connect it to a subnet with the two Dell systems. Some goals for my setup are: - Easy provisioning of the virt-hosts so I can quickly test on Fedora and CentOS without spending lots of time reinstalling - Ability to test block and nfs storage - Automation of test scenarios involving engine and hosts To help me reach these goals I've deployed cobbler on my laptop and it does a pretty good job at managing PXE boot configurations for my hosts (and VMs) so they can be automatically intalled as needed. After viewing Yaniv's presentation, it seems that Forman/Puppet are the way of the future but it does seem a bit more involved to set up. I am definitely curious if others are using Foreman in their personal dev/test environment and can offer some insight on how that is working out. Thanks, and I look forward to reading about more of your setups! If we get enough of these, maybe this could make a good section of the wiki. -- Adam Litke

------=_Part_21030313_114145744.1408031561755 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi All, The proposed feature will allow defining an arbitrary network in the DC as the management network for the cluster, which in its turn will allow assigning different VLANs for the management networks in the same DC. Feature page can be found here - http://www.ovirt.org/Features/Management_Network_As_A_Role . Please take a look into the page especially into "Open issues" section. I'd like to have your opinions on that.

Proposal for Host Networking API
by Moti Asayag 21 Aug '14

21 Aug '14

Hi All, The existing host networking API suffers from several deficiencies: 1. Part of it is a deprecated api designed for 3.0 clusters 2. SetupNetworks api introduced on 3.1 which is too complicated and verbose on the one hand, and incapable to natively support network topologies such as an isolated networks (network which isn't configured on any network interface). The complete list of deficiencies is listed on [1]. I'd like to propose an alternative API which addresses the existing issues and will allow us to support new networking features [1]. In addition, there are requests samples on [2] to demonstrate how the api should be called in order to achieve few of most commonly used network configurations. Please review and share your feedback. [1] http://www.ovirt.org/Features/HostNetworkingApi [2] http://www.ovirt.org/Features/NetworkingApi Thanks, Moti
