Please re-read me. I'm already have working setup with automatic
created tap devices (i'm use docs from this links and i have qemu runs
with root privileges and have all needed config options).
But after this patch i have error like i send.
Also i have one tc entry added before error:
qdisc pfifo_fast 0: dev tap10339 root refcnt 2 bands 3 priomap 1 2 2
2 1 2 0 0 1 1 1 1 1 1 1 1
I think that this tc entry (that i mentioned i early email) added
before tap device created via qemu. May be need to fix ordering....
What do you think?
Thanks for help!
Your original error message was that qemu couldn¹t find a tap device. So,
I am not sure how the above error relates to your original error.
Can you write your detail configuration setup and the steps you have taken
to get at this error?
