Does anybody know any packages out there for kvm which are compiled with RBD support?

I have these installed right now:

ii  kvm                              1:1.1.2+dfsg-6+deb7u8         amd64        dummy transitional package from kvm to qemu-kvm
ii  qemu-kvm                         1.1.2+dfsg-6+deb7u8           amd64        Full virtualization on x86 hardware
ii  libvirt-bin                      1.2.9-9~bpo70+1               amd64        programs for the libvirt library
ii  libvirt-clients                  1.2.9-9~bpo70+1               amd64        programs for the libvirt library
ii  libvirt-daemon                   1.2.9-9~bpo70+1               amd64        programs for the libvirt library
ii  libvirt-daemon-system            1.2.9-9~bpo70+1               amd64        Libvirt daemon configuration files
ii  libvirt0                         1.2.9-9~bpo70+1               amd64        library for interfacing with different virtualization systems
ii  python-libvirt                   1.2.1-2~bpo70+1               amd64        libvirt Python bindings

Building kvm on my own seems to be very difficult since it has many dependencies including gui libraries.

Thank you!

qemu, libvirt and virt-manager support RBD on Fedora.

Interestingly I did not see support on CentOS 7.

In order to run rbd block devices with kvm, you need to check out whether the emulator qemu has the support of ceph or not.

To do this, 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 check 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.

If rbd is not there, what you can do is to build qemu from source with rbd support enabled

git clone git://git.qemu.org/qemu.git
cd qemu
./configure --enable-rbd
make; make install
