After searching the forum and alot of trial and error i figured out how to throttle bandwidth. I used the script below. Where it says IF= i put the "tap id" that i got from running ifconfig. Example:
tap313i0d0 Link encap:Ethernet HWaddr 7a:71:f6:1e:0a:fb
inet6 addr: fe80::7871:f6ff:fe1e:afb/64 Scope:Link
UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1
RX packets:15232575 errors:0 dropped:0 overruns:0 frame:0
TX packets:24048846 errors:0 dropped:0 overruns:125 carrier:0
collisions:0 txqueuelen:500
RX bytes:1020621207 (973.3 MiB) TX bytes:31764432398 (29.5 GiB)
So the IF= would look like (in my case) IF=tap313i0d0 The numbered part corresponds with the VMID.
Where it says ip i put the ip of the virtual machine.
I placed this file in /etc/init.d/shape313
i run it by /etc/init.d/shape313 start
If want throttle more then one VM create a other file plug in the IF= and address= for that VM .. name the file something else and run it.
I hope this helps someone ... i know it helped me!
