I'm sorry but this is the KVM Host Machine there is no ceph running on
this machine.
If i change the admin socket to:
admin_socket=/var/run/ceph_$name.sock
i don't have any socket at all ;-(

If you add admin_socket=/path/to/admin_socket for your client running
qemu (in that client's ceph.conf section or manually in the qemu
command line) you can check that caching is enabled:
ceph --admin-daemon /path/to/admin_socket show config | grep rbd_cache
And see statistics it generates (look for cache) with:
ceph --admin-daemon /path/to/admin_socket perfcounters_dump
This doesn't work for me:
ceph --admin-daemon /var/run/ceph.sock show config
read only got 0 bytes of 4 expected for response length; invalid

Oh, it's 'config show'. Also, 'help' will list the supported commands.
Also perfcounters does not show anything:
# ceph --admin-daemon /var/run/ceph.sock perfcounters_dump
{}
There may be another daemon that tried to attach to the same socket file.
You might want to set 'admin socket = /var/run/ceph/$name.sock' or
something similar, or whatever else is necessary to make it a unique file.
~]# ceph -v

Out of curiousity, what patches are you applying on top of the release?
