答复: Openstack--instance-boot-from-ceph-volume:: error could not open disk image rbd

["wanhai_zhu" <wanhai_zhu@xxxxxxxxxx>]

Because of the latest librbd version, the image format has been changed from “rbd:pool/image” to “pool/image”.

 

So you see the error msg “ could not open disk image”.

Hello,

Does your qemu supports RBD images ?

See in the last line of, supported formats :
qemu-img -h

I had the same thing recently, using Debian wheezy, where qemu does not supports RBD.
