To Reproduce Setup LXD node and Linuxcontainer marketplace, try to import container to ceph datastore.

Expected behavior Container image is created to ceph datastore

Details

• Affected Component: Sunstone, Storage
• Hypervisor: LXD
• Version: 5.8.0
• Ubuntu Xenial

Additional context I did install LXD node package to existing KVM node with ceph backend and reimported host with alternative name as LXD node:

echo "deb http://archive.ubuntu.com/ubuntu $(lsb_release -cs)-backports main restricted universe multiverse" >> /etc/apt/sources.list
apt update
apt install lxd=3.0.3-0ubuntu1~16.04.1 liblxc1=3.0.3-0ubuntu1~16.04.1 lxcfs=3.0.3-0ubuntu1~16.04.1 lxd-client=3.0.3-0ubuntu1~16.04.1 -y
apt-get install opennebula-node-lxd rbd-nbd -y

I’ve added the kernel and luminous requirement to the doc, if the marketplace import issue persists, feel free to open another issue. Thanks for the feedback.
