Re: [ovirt-users] Using ceph volumes with ovirt

Hi, just to answer myself, I found these instructions that solved my problem: http://7xqb88.com1.z0.glb.clouddn.com/Features_Cinder%20Integration.pdf Basically, I was missing the step to add the ceph key to the Authentication Keys tab of the cinder External Provider. It's all working now.

The ceph cluster is managed via openstack cinder and I can create correctly the disk via ovirt (3.6.6.2-1 on CentOS 7.2). The problem comes when trying to hotplug, or start a machine with the given disk attached. In the vdsm log of the host where the VM is running or starting I see the following error: jsonrpc.Executor/5::INFO::2016-05-30 10:35:29,197::vm::2729::virt.vm::(hotplugDisk) vmId=`c189472e-25d2-4df1-b089-590009856dd3`::Hotplug disk xml: <disk address="" device="disk" snapshot="no" type="network"> <source name="images/volume-9134b639-c23c-4ff1-91ca-0462c80026d2" protocol="rbd"> <host name="141.108.X.Y1" port="6789" transport="tcp"/> <host name="141.108.X.Y2" port="6789" transport="tcp"/> </source> <auth username="cinder"> <secret type="ceph" uuid="<base 64 ceph secret>"/> </auth> <target bus="virtio" dev="vdb"/> <driver cache="none" error_policy="stop" io="threads" name="qemu" type="raw"/> </disk> jsonrpc.Executor/5::ERROR::2016-05-30 10:35:29,198::vm::2737::virt.vm::(hotplugDisk) vmId=`c189472e-25d2-4df1-b089-590009856dd3`::Hotplug failed Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 2735, in hotplugDisk self._dom.attachDevice(driveXml) File "/usr/share/vdsm/virt/virdomain.py", line 68, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", line 124, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 1313, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 530, in attachDevice if ret == -1: raise libvirtError ('virDomainAttachDevice() failed', dom=self) libvirtError: XML error: invalid auth secret uuid In fact the uuid of the secret used by ovirt to hotplug seems to be the ceph secret (masked here as <base 64 ceph secret>), while libvirt expects the uuid of the libvirt secret, by looking at the instructions http://docs.ceph.com/docs/jewel/rbd/libvirt/. Anyone got it working?
