Okay you moved this to qemuDomainXMLFromNative, so now a direct call
to qemuParseCommandLine will produce an invalid virDomainDefPtr as
def->name can be NULL when -name was not given in the command line. It
seems that this is okay for now as the only caller is currently
qemuDomainXMLFromNative. You added a second caller in 8/8 that
explicitly deals with def->name == NULL.
Might be worth a comment to qemuParseCommandLine that mentions this.

ACK.
