[Openstack] How to integrate Cloudsim
Hi all, I just wonder how to integrate Cloudsim(https://code.google.com/p/cloudsim) into Openstack, that is to say i wanna use Cloudsim in local clouds with Openstack. Would anyone please give me some suggestions about this one? Or give me an example patch that is integrated into Openstack.

[Openstack] How to get debug logs in Openstack Cinder
Hi all,
I add some print logs for cinder/cinder/volume/drivers/sheepdog.py
like following.
[...]
57 def create_volume(self, volume):
58 Creates a sheepdog volume
59 LOG.debug(_('999 volume name is %s') % volume['name'])
^
60 self._try_execute('qemu-img', 'create',
61 sheepdog:%s % volume['name'],
62 '%sG' % volume['size'])
[...]
However, i could not catch this, LOG.debug(_('999 volume name is %s')
% volume['name']),
logs by 'screen -r'. How could i get the logs? Maybe i should print
logs with other formats, right?
Has anyone add print logs for openstack? Please give me some
suggestions. Thanks a lot ;-)

Hi Hirendra Rathor,
I was getting same error when I picked up devstack for the first time few
days ago. I could have tried troubleshooting it but I wasn't particularly
happy with the fact that I had to launch stack.sh every time on reboot. The
script updates the source code and then compiles it which means that the
product behavior could be different after running the script. This is not
necessarily a problem but I felt less in control.
I, therefore, modified my local copy of stack.sh to _not_ do operations that
should be required for the first run. Examples of such operations include
creating user accounts, configuration files, mysql database etc. The result
was a script that just launches the openstack processes. Running this lean
script resulted in successful launch of keystone process, so I didn't have
to troubleshoot the original problem!
I am not clear about how you can solve 'keystone did not start'.
Cloud you please attach your modified stack.sh, which solved this problem.
Now, i can get some logs for my 'keystone did not start' like following.
$ screen -S stack -p key -X stuff

[Openstack] [Sheepdog][Libvirt][Qemu]Add a new block storage driver by Libvirt/Qemu way for Openstack
Hi all, I wanna add a new block storage driver by Libvirt/Qemu way for Openstack, which is as same as Sheepdog driver for Openstack. So i think the theories are like this. 1, In the Openstack Nova branch, Openstck driver call libvirt client and send parameters to libvirt client.(From this point, i should modify Openstack Nova source codes. They are a, nova/nova/virt/libvirt/driver.pyadd new driver way b, /OpenStack/nova/nova/tests/test_libvirt.py add new driver test) 2, According to own protocol, libvirt client in Openstack Nova branch send parameters to Libvirt server.(From this point, i should modify libvirt library to let libvirt library support this new driver like Sheepdog). 3, Libvirt server call Qemu interfaces to send parameters to Qemu.(From this point, i should modify Qemu source codes to let Qemu support this new driver like Sheepdog). 4, In Openstack Cinder branch, Openstack driver use Qemu commands to create this new volumes to Qemu.(From this point, i should modify Openstack Cinder branch source codes like this. a, Add new driver file /OpenStack/cinder/cinder/volume/drivers/new_driver.py like Sheepdog.py b, Change file /OpenStack/cinder/cinder/tests/test_drivers_compatibility.py to test new driver). 5, At last, i should also modify /OpenStack/manuals/doc/src/docbkx/openstack-compute-admin/tables/hypervisors-nova-conf.xml to configure this new driver.

You can use nova.virt.libvirt.volume.LibvirtNetVolumeDriver as a libvirt volume driver like sheepdog and rbd. I have the same thoughts. Morita, thanks for your help. You can also see another emali i sent to you a moment ago named Add a new block storage driver by Libvirt/Qemu way for Openstack, which says how to add a new block storage for Openstack in details.
