Support for up to 16 VDIs per VM on XS 6.0 and above (16 VDIs => root + cd + 14 data volumes). Currently in CS number of data disk that can be attached to VM is hard-coded to 6. Made this setting configurable by moving it to hypervisor capabilities. Although XS 6.0 and above supports upto 16 VDIs but while testing on XS 6.0.2 found that only 13 data volumes can be attached to a VM. So for XS 6.0 and 6.0.2 max_data_volumes_limit is set to 13 currently.

I've renamed discover to discoverer to fix the issue. My ant debug fails
with:
[java] ERROR [utils.component.ComponentLocator] (main:) Unable to
load configuration for management-server from components.xml
[java] com.cloud.utils.exception.CloudRuntimeException: Unable to
find class: com.cloud.hypervisor.kvm.discoverer.KvmServerDiscoverer

This patch adds RBD (RADOS Block Device) support for primary storage in combination with KVM.
To get this patch working you need:
- libvirt-java 0.4.8
- libvirt with RBD storage pool support (>0.9.13)
- Qemu with RBD support (>0.14)
The primary storage does not support all the functions of CloudStack yet, for example snapshotting is disabled
due to the fact that backupping up a RBD snapshot is not possible in the way CloudStack wants to do it.
Creating templates from RBD volumes goes well, creating a VM from a template however is still a hit-and-miss.
NFS primary storage is also still required, you are not able to run your System VM's from RBD, they will need
to run on NFS.
Other then these points you can run instances with RBD backed disks.
un-allocated space is insufficient on primary storage
check the availability of un-allocated primary storage space during
planning stage, for multiple-volume VM creation scenario
modification in StorageManagerImpl.java and StorageManager.java:
add a new method storagePoolHasEnoughSpace(List<Volumes>, StoragePool),
check if storagePool has enough space for all requested volumes
modification in FirstfitPlanner.findPotentialDeploymentResources:
handle multiple volume case, keep track of allocated volumes for pools
and call storagePoolHasEnoughSpace to check space availability
modification in AbstractStoragePoolAllocator.java:
extract capacity computation logic and make a new method in
StorageManagerImpl

Issue happens when ROOT volume gets created and there is subsequent failure in starting the VM. During retry if allocator assigns a different storage pool the scenario was not handled. Now in case of local storage the volume get recreated on the newly assigned pool and old one gets cleaned up. In case of shared storage the existing volume is migrated to new storage pool.
When a host is not considered for deployment because it has disabled HVM, then call that out in the logs for debugging.
