Hi,
Here are a few more improvements to the qemu rbd support. The first
patch makes the configuration file handling cleaner (do not error out if
/etc/ceph/ceph.conf doesn't exist). One allows characters in the conf
string to be escaped, so you can (for example) specify an ip\:port (':'
is used as a delimiter).
The last patch implements flush when rbd_flush() is available. This lets
us take advantage of write buffering in newer versions of librbd, which
improves performance significantly for many workloads (including the
trivial qemu-img convert).
Thanks!
