Hi, I am a newbie OpenNebula user and I have a problem… I just finished installing the opennebula system with only one kvm virtualization host (centos 6.9 final) and I tried to run multi istances of ttylinux-kvm images but only the first start regularly the others remain in Pending status. Then I tried to run ttylinux-kvm and Ubuntu 16.04 - LXD together but again only the first runs… the second stay pending. where is the error? thank you all ---

@fbordini, you need to install [LXDoNe addon](https://github.com/OpenNebula/addon-lxdone) in order to manage LXD containers on OpenNebula. **Ubuntu 16.04 - LXD** is an LXD container image. OpenNebula doesn’t support multi instances nodes by default. As a workaround, you can follow the guides to prepare the same node to run KVM virtual machines and LXD containers and add it to OpenNebula twice (as a KVM node and as an LXD node). This way you can deploy KVM VMs and LXD containers on the same node 😉 ---

Have you tried to instantiate it manually? There’s no much info on the sched.log more than the scheduler couldn’t find a host that matches the criteria to deploy VMs 🙁 ---

I have not tried manually, but I have installed a new host node and I have instanced a second VM. It works … but I must create N identical VMs in a same node and now it does not work. The next week I will try manually … I keep you updated. Bye ---

LXDoNe is an addon, its not provided by default by OpenNEbula. If you want OpenNebula to manage LXD containers then yo have to install the addon. ---
