Xen users - Jun 2008 - Monitor/Restrict network traffic of XEN Client

Hi List,

(Long time lecher, first time poster)

Not sure if this is the best place to ask, but here goes..

I have a few test Guests on a Xen host, and I would like to start monitoring
(and maybe restricting) the network traffic of the guests but not the Host.

No I know this can be done with iptables, but I just wondered if anyone knew
of a package or how-to to set this up with Xen on CentOS 5 ?

If this is way OT, then please let me know and I will hunt for another list
to post to...

Thank You for your help...

I know there''s a good howto on this subject on the OpenVZ forums, which
will work the same for Xen as well. Check it out

So I give my users a weight equal to the amount of ram they buy.

Right now, I''m doing this by hand...

xm sched-credit -d test -w 64  

in this case.  works great.

so, I was poking around thinking about atuomating this today...

xm create --help-config

gives me:
---
cpu_weight=WEIGHT    Set the new domain''s cpu weight.
                     WEIGHT is a float that controls the domain''s share
of
                     the cpu.
---

bootloader = "/usr/bin/pygrub"
cpu_weight=64
memory = 64
name = "test"
vif =
[''vifname=test,ip=216.218.223.103,bridge=xenbr0,mac=aa:00:00:53:31:67''
]
disk = [
        ''phy:/dev/boar_domU/test_boot,sda,w'',
        ''phy:/dev/boar_domU/test,sdb,w''
]


but it does nothing. 

[root@boar lsc]# xm sched-credit -d 2
{''cap'': 0, ''weight'': 256}



this is on CentOS 5.1
