The issue about OpenStack related with Ceph. Thus, I was following documentation in Ceph website on how integrate Ceph with existing OpenStack environment. I used Folsom with two nodes. I just configured Ceph with Cinder and Glance and I could make RBD as storage backend for Glance. Still with volumes that i was looking for to boot from it. I proceed afterwards by : 1. create a new rbd pool on ceph; 2. create new volume [cinder create volume 2 for example]; 3. Check if the new volume is added to ceph pool created --> success 4. Finally boot form volume : nova boot --flavor m1.tiny --image precise-ceph --block_device_mapping vda=ID_VOL:::0 --security_groups=default boot-from-rbd last step failed : Instance created but with Error Status. We could check inside the /var/lib/nova/instance/instance_id/lilbvirt.xml an intersting section: <disk type="network" device="disk"> <driver name="qemu" type="raw" cache="none"/> <source protocol="rbd" name="rbd/volume-e5d5f756-7a9d-47b1-a59d-504c9cf582d5"/> <target bus="virtio" dev="vda"/> </disk>
I'm not so familiar with OpenStack, but looking at the XML from libvirt I'm missing a "secret".
Are you using cephx? If so, did you define a libvirt secret and configure the UUID in Nova?

basically it seems that the opensstack recognized for RBD using the virtio driver. We could check the log file 'nova-compute.log' the follwing error line: self._set_instance_error_state(context, instance['uuid']) TRACE nova.openstack.common.rpc.amqp libvirtError: internal error Process exited while reading console log output: char device redirected to /dev/pts/6 TRACE nova.openstack.common.rpc.amqp kvm: -drive file=rbd:rbd/volume-e5d5f756-7a9d-47b1-a59d-504c9cf582d5,if=none,id=drive-virtio-disk1,format=raw,cache=none: error connecting it seems that the if field shows none. Is there any explanation that KVM can't read that volume ?
