Hi! >Which ceph.conf do you talk about ? >The one on host server (on which vm is running) ?
Yes, that ceph.conf on client host, which is not part of a ceph cluster (no OSD, no MON) and it used solely to run VMs with RBD backend. >Interesting, can you explain this please ? I think, that libvirt "cache=writeback" option turns on rbd cache only for VM, where it specified. But, if you have a "client" section with enabled rbd cache in ceph.conf on client node (as I have), it overrides per-VM setting. So writeback cache is always used (maybe by librbd backend itself), even "cache=none" specified in VM config.
