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.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
