[Qemu-devel] Status of query-netdev QMP command

[Qemu-devel] Status of query-netdev QMP command

[Roger Pau Monne]

Hello,

I've read from the GSoC/2010 that some work was being done creating a 
query-netdev QMP command:

http://wiki.qemu.org/Google_Summer_of_Code_2010/QMP#query-netdev

The status says that "mentor has merged it into his tree", but I cannot 
see this command anywhere upstream, and it will come really handy for 
what I'm trying to do, do someone know where this has gone?

Thanks, Roger.

I checked qemu.git/master and don't see it either.  The HMP "info net"
command lists the net devices but I'm not aware of a QMP equivalent.
What are you trying to do?

On Linux you can pass the name of the tap device you wish to create, and 
Qemu honors that, but on BSD systems you have no way of creating a tap 
device with a specific name, they are assigned based on the lowest free 
number (tap2 for example).

I need the query-netdev command in order to get the name of the device 
that Qemu creates, so I can use it in my scripts afterwards.

Roger.

Can you use -netdev tap,script=mycallback.sh to do that?  It gets
passed the interface name as argv[1].
