Importing vms from kvm is very easy in 4.0, you just import the vm, ovirt will do everything for you in few clicks. We don't support yet copying disks to ceph, only creating new disks. This should work: 1. Create vm with ceph disk 2. Find the ceph disk name in cinder using the disk name in engine 3. Copy the image manually to ceph using ceph command line tools The machine copying the disks should have cephx auth keys deployed. Note that ovirt hosts do not deploy ceph auth keys on the host, we deploy the keys dynamically using libvirt secrets, so only vms that need access to ceph disk can access it. Adding Daniel to add more details on how to find the cinder disk. There are some ceph users on this list, maybe they can add more details. Nir
