The auto-generated WWN comply with the new addressing schema of WWN: <quote> the first nibble is either hex 5 or 6 followed by a 3-byte vendor identifier and 36 bits for a vendor-specified serial number. </quote> We choose hex 5 for the first nibble. And for the 3-bytes vendor ID, we uses the OUI according to underlying hypervisor type, (invoking virConnectGetType to get the virt type). e.g. If virConnectGetType returns "QEMU", we use Qumranet's OUI (00:1A:4A), if returns ESX|VMWARE, we use VMWARE's OUI (00:05:69). Currently it only supports qemu|xen|libxl|xenapi|hyperv|esx|vmware drivers. The last 36 bits are auto-generated.
