[libvirt] [Libvirt][Sheepdog]How to test network disk support for sheepdog in Libvirt

Hi all, Morita added network disk support for Libvirt, which supported nbd, rbd, sheepdog, and other protocols. Now, i wanna test network disk support for sheepdog solely. I have following questions. Could anyone please give me some suggestions? Thanks in advance. 1, Before this test, whether should i build the environment of sheepdog or other projects (QEMU)? 2, How could i test network disk support of sheepdog in Libvirt? Which steps should i do for it? 3, Network disk support can support online storage management, right? -- Thanks Harry Wei
