Hi Morita, I just wanna test if sheepdog works well in libvirt. I am not sure if i can only use libvirt environment to finish this test? Or maybe i should also set up QEMU/Sheepdog/Openstack environment, right? I have done following jobs. 1, git clone git://libvirt.org/libvirt.git 2, cd libvirt 3, git reset --hard v0.9.13 4, ./autogen.sh && make NOTE: Step 3 just call back to libvirt version 0.9.13, which you, Morita, patched for Libvirt at around this version. (Your patch is here http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=036ad5052b43fe9f0d19...) I just wanna study the original patch for libvirt. After step 4, if i can use tool virsh(under libvirt/tools dir) to test sheepdog driver? Therefore, i am not sure how i should use tool virsh to test if Sheepdog driver works well in libvirt. If i can finish this test only with libvirt ENV.?(Or also should set up QEMU/Sheepdog/Openstack environment) How should i do next step?

You can create a pool based on Sheepdog with $ virsh pool-create pool.xml and create a shepdog volume with $ virsh vol-create vol.xml Example XML descriptions are available on the libvirt documentation page: http://libvirt.org/storage.html#StorageBackendSheepdog See also 'virsh help'.

Therefore, we cannot see the changes you did in libvirt/src/qemu/qemu_conf.c file of latest libvirt git tree. I have also searched all the logs libvirt developers did for sheepdog driver, which they did not modified your patch completely. All the sheepdog change logs can be seen here. http://libvirt.org/git/?p=libvirt.git&a=search&h=HEAD&st=comm...
