3, Morita said if QEMU does not support Sheepdog then Libvirt will not
support Sheepdog but i am not clear about their communicating details.
Could you please tell me their communicating details?
If QEMU doesn't officially support your file system, we cannot use
your system from VMs without applying your patch - libvirt shouldn't
support such kind of system. This is what I wanted to say, so I
suggested you to start from QEMU. I'm not sure how libvirt
maintainers think about this, though.
Thanks,
