MicroCloud, now with OVN!

[@andrewwilson7169]

Can you explain the networking a little more please? I am trying to set this up in a dev environment in vm's on seperate servers, but I can't figure out how to configure a separate network that ovn can use. I currently have a means of linking lxdbr0 to my lan network via a bridge br0, so I can easily get lan IP's or lxdbr0 ip's by launching containers with different profiles, and I know how to create e.g. a seconf lxdrbr1 and attach it to a container, but you lost me at your description of vlans and such. I tried searching the lxd discussion blog and I am none the wiser. Can you point us to more specific instructions on how to create the ovn network as you summarize from 3:52 onwards in the video please?

what is the difference between microcluster and microcloud?

[@LXD]

microcluster is an implementation detail, it's a shared code base we used to create microceph, microovn and microcloud. It's also being used by other teams to create similar services.

Hi, I'm trying to make a home lab, due to the new update MicroCloud got my attention, the problem is: I do have a six-core 12TB (16TB Raid 5) as storage and a 2x 10-core to use as compute, but I don't have the third machine that I don't even get why would I need it. Is it possible for me to use microcloud or would I need to get a third machine for this? Would it work if I install Ceph and Ovn in the 6-core while I keep LXD on the physical 2x10-core machine?

[@victoitor]

Since there are two networks those computers are on, does the ovn network need a gateway or can the one from the other network be used?

I'm wondering how the new LXD Web GUI works with this? I assume this till works with lxd --edge?

[@LXD]

Currently the LXD UI doesn't support clustering, this is being worked on now specifically in order to get MicroCloud working with it.

I bought 3 brand new mini-PCs with an i7, 64GB ram, 2TB NVME and 512GB SATA. I installed Ubuntu 24.04 and then installed via the snap and init commands... the installation completed but never finished. I tried both the 24.04 minimized and full server. One error was a qemu error. and another was some sort of network error.

[@victoitor]

On the previous OVN video, instead of a separate network, a bridge was used. Is it also possible with microovn and microcloud?

[@LXD]

Yeah, a bridge can be used to. I haven't personally tested it, but if the UI doesn't allow it, we'll fix it as it certainly should be allowed.

[@krishnaprasad8978]

the MicroCloud allows for device failure. However, the nics of each device would be connected to the same switch. If the switch fails - the MicroCloud will fail as well. It would be great if there is a bit more explanation of how to connect the nics to the switch

[@LXD]

bonded link and mlag take care of that in most environments where HA is a requirement, routing in such environments can then use VRRP or proprietary equivalent

[@victoitor]

Is local storage always set up just as zfs or can it be set up with btrfs?

[@aceqbaceq777]

is btrfs production ready?

[@victoitor]

@@aceqbaceq777 It is, although there are some raid features which are still missing.
