[Qemu-devel] [PATCH V3 2/2] tests/test-filter-mirror:add filter-mirror unit test |
|
Date: |
Thu, 4 Feb 2016 15:43:54 +0800 |
From: ZhangChen <address@hidden>
Using qtest qmp interface to implement following cases:
1) add/remove filter-mirror
2) add a filter-mirror then delete the netdev
3) add/remove more than one filter-mirrors
4) add more than one filter-mirrors and then delete the netdev
5) add filter-mirror with:
-object filter-mirror,id=qtest-f0,netdev=qtest-bn0,queue=tx,outdev=mirror0
then inject packet from the socket connected to qtest-bn0,
filter-mirror will copy and mirror the packet to mirror0.
we read packet from mirror0 and then compare to what we inject.
del filter-mirror.
we start qemu with:
-netdev socket,id=qtest-bn0,listen=127.0.0.1:9005
-device e1000,netdev=qtest-bn0,id=qtest-e0
-chardev socket,id=mirror0,host=127.0.0.1,port=9003,server,nowait
-chardev socket,id=mirror1,host=127.0.0.1,port=9004,server,nowait
