Discussions (continued): ======================== * oVirt sdk version * On oVirt 4.0 two versions of the sdk will be supported, 3 and 4, api version 3 is provided by the ovirt-sdk-3.6 rpms, while the 4 is provided by the 4.0 ones (not ready yet), so we will be using the 3.6 until 4.0 ones are ready, when we will start to adapt to it with oVirt 5.0 as deadline * Change from json to yaml * Maybe support both at first * Nicer multiline * Comments * Nicer quoting **Approved** * Userland runs (running lago without special permissions, qemu:///session) * Network is an issue * http://blog.wikichoon.com/2016/01/qemusystem-vs-qemusession.html * https://github.com/pradels/vagrant-libvirt/issues/272 * http://comments.gmane.org/gmane.comp.emulators.libvirt/117725 * ^ have to chat with the libvirt guys on how to use that * You have to create the bridge nets with superuser privs, and then use the bridges from the conf: * A dump of the domain xml shows: <interface type='bridge'> <mac address='52:54:00:91:98:c6'/> <source bridge='virbr0'/> <target dev='tap0'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> * There’s a default bridge (virbr0) always created and available on fedora boxes (by ways of /etc/qemu/bridge.conf), is what gnome-boxes uses * Might be nice to have, even requesting root pass to create bridges when needed * Multiple ‘envs’ in the same prefix workflows, now that .lago is the default prefix path (see * Should we use multiple envs per prefix? or one prefix per env? * Allow selecting the environment, and the prefix dir **Approved** * layered images for vms (will probably have to develop ourselves, at least, the client side) * Make it work on el7 too (maybe just open/push bzs to bring in the needed libguestfs features * Export/import of vm images from prefix? On the long run, being able to export/import full prefixes? * Very interesting to have * Ovirt: * ovirt-standard-ci plugin to build vdsm/ovirt rpms * Being able to run/deploy live vdsm/ovirt (unpackaged) * Drop reposync for now * Run engine in a container/chroot + vdsm in a vm? * Action items: * Start a thread to discuss the reposync drop * Open github issues for all the agreed features * Change the ovirt 4.0 publisher to publish the 3.6 sdk (until 4.0 is ready, then publish both on 4.0 repo) -- David Caro Red Hat S.L.

[26-02-2016] Weekly lago release - 0.10.0
by David Caro 27 Feb '16

27 Feb '16

Hi everyone! This week we have a couple of very interesting new features: * Using .lago as default prefix for init, that means that if you run init with just the json configuration file, it will create the prefix at $PWD/.lago, but, if you did so, then any command that you run on any dir that's under the $PWD dir that has the .lago prefix, will be run on that prefix! For example: > cd /my/awesome/project > lago init myenv.json # this create the prefix at /my/awesome/project/.lago > cd src/mymodule > lago status # this will run on the /my/awesome/project/.lago prefix automatically! > lago start > lago shell myel7_vm ... * Ouptut format for info gathering commands, for now, just the status and snapshot -l commands. Now you can add the --out-format|-f parameter to lago, and when running a command to extract info from the prefix, it will format the ouptut (yaml, json and 'default' are implemented for now). For example: > lago -f json status { "Prefix": { "Base directory": ..., "Networks": { "n0": { "gateway": "192.168.201.1", "management": true, "status": "down" }, ... }, "UUID": "fe689d3c39d011e5b22b54ee755a00ca", "VMs": { "vm0": { "NICs": { ... }, "VNC port": null, "distro": "cirros", "metadata": {}, "root password": "123456", "snapshots": "", "status": "down" } } } } * Added the public template server as the default template repo, so you don't have to supply it each time * Using 'direct' as default libguestfs backend, that should get rid of the annoying errors when bootstrapping the domains on prefix initialization. The full changelog: http://resources.ovirt.org/repos/lago/stable/0.0/CHANGELOG_0.0.txt -- David Caro Red Hat S.L.

Testing oVirt 4.0 with Lago - which SDK should we use?
by Yaniv Kaul 22 Feb '16

22 Feb '16

Currently, the SDK that Lago uses is (at least on my Fedora): ovirt-engine-sdk-python-3.5.1.0-2.fc23.noarch I think we may need to bring in a newer SDK. 1. Which one? 2. If master - is it backward compatible to run against 3.x already? 3. Can we have them side by side perhaps? TIA, Y.

[ovirt-system-tests] What is the correct value of the engine's answer file entry OVESETUP_CONFIG/fqdn ?
by Yaniv Kaul 22 Feb '16

22 Feb '16

[ykaul@ykaul answer-files]$ pwd /home/ykaul/ovirt-system-tests/common/answer-files [ykaul@ykaul answer-files]$ grep -R "OVESETUP_CONFIG/fqdn" * |sort el6_3.5.conf:OVESETUP_CONFIG/fqdn=str:engine el6_3.6.conf:OVESETUP_CONFIG/fqdn=str:*localhost.localdomain* el6_master.conf:OVESETUP_CONFIG/fqdn=str:engine el7_3.5.conf:OVESETUP_CONFIG/fqdn=str:engine el7_master.conf:OVESETUP_CONFIG/fqdn=str:engine Is the value localhost.localdomain correct for el6-3.6 (only?). TIA, Y.

Lago mailing list archives
by David Caro 02 Feb '16

02 Feb '16

Hi everyone!! Last week we realized that the archives for the mailing list were not working, and that has been solved today. Painfully all the emails that were sent before were not actually archived so they have been lost in the archives, but from now on they will be properly archived and backed up. Sorry for the inconvenience :/ -- David Caro Red Hat S.L.
