[lxc-users] Fwd: Linux container network bandwidth

[Nguyễn Thành Long]

Hi Divya,



I also have had a similar problem and stuck on it till now. I didn't use 1)
cos I used an unprivileged container. But I think your problem is *0x1001. *Try
replacing with *0x00100001*. ( = 10:1)

The format for net_cls.classid is 0xAAAABBBB; AAAA is the major handle
number and BBBB is the minor handle number.

Hope this helps.
