I'll follow that and see what I learn. The vdsm side may be similar since both are network disk device. There are only 2 steps needed to start up a VM with rbd. qemu-img create -f rbd rbd:data/host1 10G Then to start the image for qemu add -drive file=rbd:data/host1,if=none,id=drive-virtio-disk0,format=raw or within libvirt: <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='rbd' name='data/host1'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> So the steps are simple, and maybe Gluster is more complex then I should use as an example. Thanks, JOSH
