I've been working with the upstream sheepdog community to get the
userland component of sheepdog into shape for distribution. Soon the
userland rpm will be ready for review.
The userland depends on upstream QEMU 0.13 to add a block storage
device. Curious to know if there are plans to integrate this version of
QEMU into a future fedora version or if we could carry a patch on top of
current fedora qemu which integrates the functionality.
 sheepdog is a distributed block storage system for QEMU. For more
details, check out the KVM Forum slides.
