Based on patch by Nikolay Nikolaev: Vhost-user will implement the multi queue support in a similar way to what vhost already has - a separate thread for each queue. To enable the multi queue functionality - a new command line parameter "queues" is introduced for the vhost-user netdev.

Currently QEMU dynamically generates mac address for the NIC which doesn't specify the mac address. But when we hotplug a NIC without specifying mac address, the mac address will increase for the same NIC along with hotplug and hot-unplug, and at last it will overflow. And if we codeplug one NIC with mac address e.g. "52:54:00:12:34:56", then hotplug one NIC without specifying mac address and the mac address of the hotplugged NIC is duplicate of "52:54:00:12:34:56". This patch add a mac_table to record the usage status and free the mac address when the NIC is unrealized.

When -netdev tap fails, it first reports a specific error, then a generic one, like this: $ qemu-system-x86_64 -netdev tap,id=foo qemu-system-x86_64: -netdev tap,id=foo: could not configure /dev/net/tun: Operation not permitted qemu-system-x86_64: -netdev tap,id=foo: Device 'tap' could not be initialized With the command line, the messages go to stderr. In HMP, they go to the monitor. In QMP, the second one becomes the error reply, and the first one goes to stderr. Convert net_init_tap() to Error.

When -netdev bridge fails, it first reports a specific error, then a generic one, like this: $ qemu-system-x86_64 -netdev bridge,id=foo failed to launch bridge helper qemu-system-x86_64: -netdev bridge,id=foo: Device 'bridge' could not be initialized The first message goes to stderr. Wrong for HMP, because errors need to go to the monitor there. The second message goes to stderr for -netdev, to the monitor for HMP netdev_add, and becomes the error reply for QMP netdev_add. Convert net_bridge_run_helper() to Error, and propagate its errors through net_init_bridge(). This ensures the error gets reported where the user is, and suppresses the unwanted second message. While there, improve the error messages a bit.

Error reporting for netdev_add is broken: the net_client_init_fun[] report the actual errors with (at best) error_report(), and their caller net_client_init1() makes up a generic error on top. For command line and HMP, this produces an mildly ugly error cascade. In QMP, the actual errors go to stderr, and the generic error becomes the command's error reply. To fix this, we need to convert the net_client_init_fun[] to Error. To permit fixing them one by one, add an Error ** parameter to the net_client_init_fun[]. If the call fails without returning an Error, make up the same generic Error as before. But if it returns one, use that instead. Since none of them does so far, no functional change.

Option 'disable spoolss' is available since Samba 2.0.4, commit de5f42c9d9172592779fa2504d44544e3b6b1c0d). Next, "socket address" was reported as deprecated, use a combination of "interfaces" and "bind interfaces only" instead (available since October 1997, commit 79f4fb52c1ed56fd843f81b4eb0cdd2991d4d0f4).
