Giuseppe, this is a nice compilation of wishes! > Let's start from the oVirt Node: > > *) oVirt Node complete convergence with Atomic Host: start from Project > Atomic tools and define an ISO-installable Atomic Host variant  to include > gluster, qemu, libvirt, vdsm and all the packages/configurations that an > oVirt Node would need (remove unneeded parts) That's a nice idea and we actually actively investigated to use Atomic Host. Atomic is pretty strong on quickly building and deploying trees. It also provides the nice features to rollback in case of accidents, and also has a vibrant community. But we encountered a few issues i.e. Atomic has tough requirements on how the root filesystem must look, and how packages can touch/change the root file-system. Besides that we were seeing issues when it comes to support a wider range of (multipathed) storage hardware. To just name two issues. So for now we don't aim to build Node an the foundations of Atomic. But we are working on an approach which is similar to Atomic and allows us to address some long standing issues and make Node much easier to use, maintain, and customize. Stay tuned for news on the Node development road-map. > *) add oVirt Node ability to host containers (independent of the above > mentioned convergence with Atomic); note that Atomic Host has > Docker/Kubernetes, but libvirt already has a LXC driver  and the Engine > could benefit from some added smartness in managing groups of guests etc. in > the vm case too; there are related wishlist items on configuring/managing > containers on the Engine and on VDSM Actually a good point which I also had on my mind. The main focus of Node will be to host VMs, but having basic container support to host containers for supporting a feature is surely something interesting. > *) add Open vSwitch direct support (not Neutron-mediated); there are related > wishlist items on configuring/managing Open vSwitch on the Engine and on VDSM This will need work on the vdsm side before it makes sense to pull this into Node. > *) add oVirt Node ability to fully perform as a stand-alone hypervisor: I > hear that Cockpit is coming, so why not Kimchi too? ;) Yep, Cockpit will be part of the game on Node. Kimchi might be problematic - not because of Node - but because of the way how libvirtd is tuned towards vdsm. The last time I looked the issue was that libvirtd is not consumable by kimchi anymore, once vdsm has configured it. And to me it looks like this does not really fit anyway right now, because the current assumption is that Engine has the full control over VMs - and this would be not true anymore if you could use kimchi to administer your VMs. - fabian _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
