Supported Storage Configurations
Storage supported by KVM
For details on the storage supported by KVM, refer to the KVM manual
The method involving allocation of storage to VM guests supports only the following:
Entire Block Devices (such as LUN)
Due to specification changes to libvirt, when LVM partitions or physical disk partitions are allocated to a VM guest, SG_IO on the guest OS cannot be issued.
Resource Orchestrator only supports the method involving allocation of entire block devices, which allows SG_IO to be issued from the guest OS.
For details, refer to the following section in the "Virtualization Host Configuration and Guest Installation Guide".

Note
It is not possible to allocate physical disk partitions and LVM partitions to virtual L-Servers as disk resources created in advance.
Preparations for Storage Environments
Check the following:
Volumes (LUNs) to assign to the virtual L-Server have already been created
LUNs are used for virtual L-Server disks. Create the same number of LUNs as the number of necessary disks. The size of each LUN must be larger than the size of each disk.
Volumes (LUN) to allocate to cloning images have been already created
Cloning images are stored on LUNs. Create LUNs based on the number of cloning images to be created. The size of each LUN must be larger than the size of each cloning image.
Zoning and affinity have been set
When migrating VM guests for Virtual L-Servers, configure zoning and affinity, and set LUNs as shared disks.
