Okay, that's fine.

Sorry for confusing you about "comparing > 0", now the check is wrong
here and you report an error when the input is actually valid. Please
change this back to "if (!def->memory)".

Okay, no potential segfault here anymore. But a few lines below you
use def->disks[0]->src in a virBufferVSprintf call, without checking
if the first disk element is there.
So you either need to make the first disk element mandatory by
checking for def->ndisks being 0 and reporting an error in that case,
or by altering the virBufferVSprintf call to only output the
virtual_scsi_adapters=%s part when the domain XML contains a disk
element.
