Traffic Control Issues Inside Ubuntu Guest

[ElPete]

I've installed a 64 bit Ubuntu Server. I am trying to set some traffic control inside the device but I am getting an error message. I am not sure if this is an issue with my CPU, my kernel or something else.

If I enter a command for a device that does not exist, I get an error message. If I try a command for a device that DOES exist, I get an error message or blank output. For example:

Existing Device:

tc class show dev eth0 ( No output )
sh tc class change dev eth0 parent 1:0 classid 1:1 htb rate 100Mbps burst 10k ( RTNETLINK answers: No such file or directory )

Device that does not exist:
tc class show dev eth100 ( Cannot find device eth100 )
sh tc class change dev eth100 parent 1:0 classid 1:1 htb rate 100Mbps burst 10k ( Cannot find device eth100 )

Any suggestions would be appreciated.

My CPU Information:
Intel Virtualization Technology: Yes
Inter Hyper Threading Technology: No
Intey 64 Architecture: Yes

I don't believe that this is a VirtualBox issue, as searching for "RTNETLINK answers: No such file or directory" returns a lot of answers for people trying to do exactly what you're doing (traffic control). Maybe somewhere in there lies the answer?

You were right. It wasn't a VirtualBox error. I spend a lot of time on Google. The issue was the configuration of the interfaces. The qdisc was fifo and not htb so obviously setting the the htb rates wouldn't work.
