(does qemu have a > documented limit?) I don't think so. QEMU doesn't have anything documented, but they are using uint16_t to store the max_queues internally. However, when setting it in virtio_net_device_init they use: n->max_queues = MAX(n->nic_conf.queues, 1); where n->nic_conf.queues is int32_t. Maybe we should ask on the qemu list. > > >> + </attribute> >> + </optional> >> + <optional> >> <attribute name="txmode"> >> <choice> >> <value>iothread</value> -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
