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:

$ 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:

$ 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!
