[libvirt] [Libvirt][Sheepdog]How to test Sheepdog patch

Hi Morita and other developers, I have done following jobs. 1, git clone git://libvirt.org/libvirt.git 2, cd libvirt 3, git reset --hard 036ad50 4, ./autogen.sh 5, make NOTE: step 3 calls back to Morita's patch for Libvirt version, which is here http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=036ad5052b43fe9f0d19... After step 5, i have following questions. 1, I am not clear about how to test Sheepdog. Actually, i just wanna study Sheepdog driver, then i will program our driver for Libvirt. 2, I am not clear about how Sheepdog, Libvirt and QEMU communicate with each other. Before my test for Sheepdog patch for Libvirt, i have to build Sheepdog, Libvirt and QEMU environment, right? Morita, i have seen your patch for Libvirt but i do not find it calls for Sheepdog functions, so it does not have to build Sheepdog environment, right? -- Thanks Harry Wei
