[libvirt] [Sheepdog][Libvirt]How should i test sheepdog in libvirt
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=036ad5052b43fe9f0d197e8...) 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? Could anyone give me some suggestions? Thanks in advance ;-) -- Thanks Harry Wei

I wrote a minimum guide to use sheepdog volumes from virsh. Hope it would help you: https://github.com/collie/sheepdog/wiki/Libvirt libvirt-list is a place for discussions about the development of libvirt. I guess libvirt-users is a better place for you. Thanks, Kazutaka

Hmmm..., let me have a try, thanks for your jobs.
libvirt-list is a place for discussions about the development of libvirt. I guess libvirt-users is a better place for you.
You are right, i will, thanks. -- Thanks Harry Wei

Actually, i do not wanna start a VM. I just wanna test if 'virsh' can create/destroy a Sheepdog volume. The logical relationships are like this(parameters are sent): virsh --> libvirt client --> libvirt server --> qemu How should i use 'virsh' command create/destroy a Sheepdog volume? -- Thanks Harry Wei

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'.

I also have two questions. 1, Before create Sheepdog volume by virsh command, i must build Sheepdog and libvirt environment, right? 2, There are all the commit logs of Sheepdog, which can be found here. http://libvirt.org/git/?p=libvirt.git&a=search&h=HEAD&st=commit&s=sheepdog Therefore, i cannot catch the changes you made in the latest Libvirt git tree. The patch you made for Libvirt at 2010-12-09, which was merged by Eric Blake. Shoud i download Eric Blake's git tree? But where is Eric Blake's git tree? Morita, could you please tell me how i can get your patch's git tree? Your patch can be found here. http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=036ad5052b43fe9f0d197e8... Thanks for your help very much ;-) -- Thanks Harry Wei

I have solved the second question like following: 1, git clone git://libvirt.org/libvirt.git 2, cd libvirt 3, git reset --hard 036ad50 NOTE: 036ad50 is the commit SHA1 key of that patch. 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=commit&s=sheepdog -- Thanks Harry Wei

Another question is whether i have to build QEMU environment? I remeber you said if QEMU do not support Sheepdog then Libvirt do not support Sheepdog. Now, i am not clear about their communicating details. Could you please give me some suggestions? thanks. -- Thanks Harry Wei
