Subject: [Qemu-devel] [PATCH 0/3] Allow host_net_add monitor command accept file descriptors
Date: Mon, 06 Jul 2009 18:30:01 +0100 [thread overview]
Message-ID: <1246901401.12086.20.camel@blaa> (raw)
Hi,
You can pass file descriptors to qemu via the command line using '-net
tap,fd=' or '-net socket,tap='. However, you cannot currently do this
via the monitor.
libvirt always configures tap interfaces before passing them to qemu.
One reason for this is to allow libvirtd to have privileges
to /dev/net/tun without allowing qemu those privileges. Because of this,
libvirt currently does not support NIC hotplug for qemu.
The following three patches add support for passing a file descriptor
to the monitor command by allowing file descriptors to be received over
monitor commands on a unix socket.
For reference:

Cheers,
Mark.
