VIR_ERROR is logged, but not propagated back to the caller; besides,
'make syntax-check' warned that it was not a translated error message.
I'm applying this to convert to our preferred error reporting:
diff --git i/src/qemu/qemu_migration.c w/src/qemu/qemu_migration.c
index c30c40b..49a260d 100644
--- i/src/qemu/qemu_migration.c

def->uuid,
VIR_NETDEV_VPORT_PROFILE_OP_MIGRATE_IN_FINISH,

net->ifname);
+ qemuReportError(VIR_ERR_OPERATION_FAILED,

goto err_exit;
}
VIR_DEBUG("Port profile Associate succeeded for %s",
net->ifname);
ACK with that fixed, so I added you to AUTHORS (let me know if you
prefer an alternate spelling), and pushed.
