[DOC] About Defect CLOUDSTACK-302 (CLVM Support, RBD Support for
KVM)
Hello Community,
I am working on https://issues.apache.org/jira/browse/CLOUDSTACK-302.
The following features should go to the RN. I am not sure who is the contact point.
Cluster Logical VM support reappeared for KVM
RBD support for KVM
Please reach out to me if you are responsible for these features.

Sure! I'd like to point you to my personal blog first:
http://blog.widodh.nl/2012/09/ceph-distributed-storage-with-cloudstack/
When you want to run you need a KVM hypervisor with:
- libvirt >= 0.10.1
- Qemu with RBD enabled
I recommend a Ubuntu 12.04.1 hypervisor with the Debian packages from
the Ceph website: http://eu.ceph.com/docs/master/install/debian/
libvirt will have to be compiled by hand for now, since 0.10.1 hasn't
been packaged yet.
Other then Qemu and libvirt it should work out of the box with 4.0

1.
lack of rbd documents.
anyone could give a step by step setup. cloudstack,qemu,libvirt,distro version.....
2.
which distro is preferable for cloudstack. i use centos6.2,but i have to build qemu,libvirt from source code ,update many software version to support rbd.

Thank you Marcus.
I was going through the RedHat documentation to understand CLVM (https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/LVM_Cluster_Overview.html)
Your description has more details.

I can give a more detailed description tomorrow if needed, but in general the feature has not changed since it was introduced in 3.0. It was pulled due to licensing and I added the functionality back, so people upgrading will see no difference.
The CLVM feature for KVM allows for root and data disks (primary storage) to reside on Linux logical volumes. Administrators are required to manage/configure the CLVM on the KVM hosts independent of cloudstack. Once the volume groups are available, an administrator simply adds primary storage of type CLVM, providing the volume group name. Then cloudstack will create and manage logical volumes as needed.
Snapshots are also supported. Cloudstack will create an LVM snapshot, copy off the applicable logical volume to secondary storage in qcow2 format, and then delete the LVM snapshot.
