CentOS - Feb 2013 - How to limit upload bandwidth for a KVM guest?

Hello:

I am using a CentOS server as a KVM host using bridged networking
for the guest servers.

I would like to limit the bandwidth available to a guest.  I tried using
the tc command, but it is only limiting the download speed to the
guest.

Is there a way to limit the upload speed from the guests?

Thanks,
  Neil

Hmm interesting...

I've not had a need to do this but in theory cgroup configuration might be
able to help.

Is this c5 or c6?

Hi,
I tried to install CentOS 4.1(x86_64) on my virtual machine.
I am getting kernel panic error. Installation program crashed.
I also tried CentOS 4.0 and CentOS 4.2, got same error.
There is  no  problem  with  installing  CentOS 4.1(32  bits).

Can you help me regarding this?
What is the more stable version of centOS 4.

Thanks & Regards,
Raja

4.0, 4.1, and 4.2 were released a few months apart in 2005, built with 
kernel 2.6.9.   why are you installing 8 year old software on a new system ?

if you absolutely have to run a EL4 derivative, at least run 4.9, which 
was released in 2011, but be aware there have been no security fixes for 
it since a year ago.

TC is fairly complex, and only really effectively limits speed sent.  If 
you want to limit the upload speed of a guest, you'd put the rules on 
the interface that hosts the default route for traffic from the guest.

Shorewall does a reasonably good job of dealing with most of the 
complexity of tc under Linux.

You need to read about 'tc'.
