Check if KVM has the support of Ceph

As you may know Ceph is not part of Debian Wheezy, thus QEMU-KVM was not compiled with the Ceph support (--enable-rbd with both librbd and librados). This article is just a quick tip to detect if your QEMU-KVM has the support of Ceph.

First check QEMU-KVM:

bash $ sudo qemu-system-x86_64 -drive format=? Supported formats: vvfat vpc vmdk vhdx vdi sheepdog sheepdog sheepdog rbd raw host_cdrom host_floppy host_device file qed qcow2 qcow parallels nbd nbd nbd dmg tftp ftps ftp https http cow cloop bochs blkverify blkdebug

And look for rbd in the output!

Then QEMU-UTILS:

bash $ qemu-img -h ... ... Supported formats: vvfat vpc vmdk vhdx vdi sheepdog sheepdog sheepdog rbd raw host_cdrom host_floppy host_device file qed qcow2 qcow parallels nbd nbd nbd dmg tftp ftps ftp https http cow cloop bochs blkverify blkdebug

And look for rbd in the output!

That's it!
