Re: [libvirt] [PATCH v6] npiv: Auto-generate WWN if it's not specified
2012/2/7 Osier Yang <jyang(a)redhat.com>:
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.
A step in the right direction :)
But why should we use a string here and call virConnectGetType when we
already have a virDomainVirtType enum and the virDomainDef struct has
a virtType member that holds the required information?
