Greetings, CloudStackers. I noticed there was a question re: libgfapi as it
pertains to libvirt and QEMU.
As of last January/February, all new versions of the KVM/QEMU/libvirt/oVirt
virtualization stack have been "glusterized" and use the libgfapi client
library when you specify the gluster protocol in QEMU.
You can see this old presentation here that goes over some of these topics:
http://www.gluster.org/community/documentation/images/9/9d/QEMU_GlusterFS.pdf
That presentation is almost a year old and much of what was listed as
in-progress is now in an official release.
What this integration means for you is that you should be able to spin up and
manage VM images on Gluster volumes directly through libgfapi, which bypasses
the fuse mount. This is especially useful for use cases such as VM image
hosting, and the performance gains are pretty dramatic.
I've CC'd the Gluster-devel list, as well as some of the engineers who were
working on the integration. If you have specific questions, make sure to keep
gluster-devel on the CC list so that they can respond.
Thanks!
