This introduces new element <wwn> for disk, to allow to set wwn
(just like setting serial number) for the virtual disk (Only QEMU
devices like ide-drive, ide-hd, ide-cd, scsi-disk, scsi-hd, and
scsi-cd support it).
Osier Yang (4):
schema: Add schema for disk <wwn>
conf: Parse and format disk <wwn>
qemu: Add caps to indentify if setting wwn is supported by qemu
qemu: Use disk wwn in qemu command line

What happens if the wwn was not passed?
If it is NULL, it's a bug (same for serial).
If it is empty, the output will not obey the schema, so the whole

serial, but technically it should be ok.

Oh, sure, v2 will have it.

virBufferEscapeString() is magic - if def->wwn is NULL, then the entire
output string is omitted from buf. We use that idiom all over the place.
If it is NULL, it's a bug (same for serial).
If it is empty, the output will not obey the schema, so the whole
element should be left out.
Yep, that is what will happen, with the code as-is.

See Eric's follow up explaination. I was also confused about it
before not looking into virBufferEscapeString one step further
though. :-)

Do we really need regcomp() for this? I'm thinking it's much faster to
just do something like:
for (i = 0; wwn[i]; i++)
if (!c_isxdigit(wwn[i]))
break;
if (i != 16 || wwn[i])

just do something like:
for (i = 0; wwn[i]; i++)
if (!c_isxdigit(wwn[i]))
break;
if (i != 16 || wwn[i])
// error, return false;
return true;
Which is more compat, I posted a v3, thanks.

I checked it by:
+ if (disk->wwn) {
+ if (disk->device == VIR_DOMAIN_DISK_DEVICE_LUN) {
+ virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s",
+ _("Setting wwn is not supported for lun
device"));
+ goto error;
+ }
No words "scsi-block" though, that's why I guess you missed it. :-)
