just a question… I’d like to adding and manage my LXD containers with MAAS, is there a way to make that without use KVM?
thanks
No, containers can’t PXE boot so MAAS can’t provision them, nor does it now how to start/stop them.
LXD can integrate with MAAS but that’s on the IP allocation and tracking side of things only.
I’ve found this post where he creates a container and inside that a KVM. Then in MAAS is present the VM. I’ve tried to realize that with these steps:
$: lxc launch images:ubuntu/bionic/amd64 ulab-juju-gui
$: lxc exec ulab-juju-gui bash
then I’ve installed on it KVM:
root@ulab-juju-gui:~# sudo apt install qemu-kvm libvirt-bin virtinst -y
root@ulab-juju-gui:~# exit
and then on my host:
$: lxc exec ulab-juju-gui – virt-install
–name=juju-controller
–os-type=Linux
–os-variant=ubuntu18.04
–ram=4096
–vcpus=2
–disk size=10
–pxe
–network bridge:virbr0
–graphics vnc,listen=127.0.0.1 --noautoconsole &&\sudo lxd --debug --group lxd
but I received that error:

There’s a way to do this now.
Check out https://maas.io/docs/add-a-vm-host and related documentation.

fantastic, thanks a lot… one of these days I’ll try that on my lab.
