Hi,
Here's a series of patches which gets the ball rolling on adding
a -netdev option.
The idea is to de-emphasise the vlan support, and instead make
a nic directly connected to a host backend the default and recommended
configuration. We want this because it is only with this configuration
that we feasibly add optimizations like GSO support or vhost-net.
Where we're going is that rather '-net user -net nic' being the
default, it would instead be:
-netdev user,id=default_slirp -device e1000,netdev=default_slirp
This patch series has a lot of this done, but there's still a
significant TODO list including:
* qdev-ify the NICs so that we can use -device rather than '-net nic'
which Gerd has started looking at
* add hotplug equivalent to netdev - we should probably add a 'nic='
argument to -netdev for this to allow changing the backend without
changing the frontend
* 'info network' should list netdevs
* merging in GSO support from qemu-kvm.git, substantially cleaned up
* VLAN support should be implemented as just another network client,
but one which is connected to multiple backends and frontends
* re-naming e.g. VLANClientState to NetClient
* killing off NICInfo
* ...
I've given this series significant testing including building
with all targets (really!), mingw, --disable-slirp, --enable-vde,
without TUNSETSNDBUF and running with various nic models, backends,
with both -net and -netdev, some different guests, hotplug, ... No
doubt I've still managed to screw something up.
Cheers,
Mark.
