Hi Simon,
problem is here.. if we directly create vol via qemu-img create -f rbd rbd:rbdpool/VM1 100G, then virsh is unable to find the vol. - virsh vol-list rbdpool command is unable to list the vol, it looks such commands - rbd, virsh and qemu-img creating images are not synced with each other...
how you manage to preform snapshot with the raw format in qemu-kvm VMs?
and i found some issues with libvirt virsh commands with ceph:
--
1) create storage pool with ceph via virsh
2) create a vol via virsh - virsh vol-create-as rbdpool VM1 100G
problem is here.. if we directly create vol via qemu-img create -f rbd rbd:rbdpool/VM1 100G, then virsh is unable to find the vol. - virsh vol-list rbdpool command is unable to list the vol, it looks such commands - rbd, virsh and qemu-img creating images are not synced with each other...
cloud you please let me know how you use the ceph as backend storage of qemu-kvm, as if i google it, most of the ceph application is used for OpenStack, but not simply pure qemu-kvm. as if setting up Glnace and Cinder is troublesome...
thank you!

without having qcow2, the qemu-kvm cannot make snapshot and other
features.... anyone have ideas or experiences on this?
thank you!
I'm using raw too and create snapshots using "rbd snap create"
Cheers,
Simon
