[CentOS-virt] how to monitor each VM's traffic?

[Rudi Ahlers]

Hi all

Can someone please tell me how to monitor each VM's traffic on a CentOS 5.2
server, running either Xen or OpenVZ? I need to bill my users for the
traffic they use, and would like to have a traffic usage graph for each Xen
/ OpenVZ Virtual Machine on the server.

Thanx :)

if you look at how xen sets up the Vif interfaces, you will note that 
its quite trivial. just watch the vif as you would an eth interface.

[Rudi Ahlers]

Sure, that's for XEN, but it's not very effective. I need graph the traffic
for each VM, not the vif - the vifs tend to change on a reboot, and also
reset with the stats.

How can I graph the traffic over a perioud of time, for any given IP
address?

Cacti works well, for switches & routers, but I can't get Cacti to graph an
individual VM on the server.

You've been on the list long enough to consider trimming your posts and 
not top posting.


also, you seem confused about what a virtual interface is. take a look 
at virsh and see how you can bring up and take down a xen domu while 
getting info on what interfaces its using and how.

Yes, but that's not going to help me. Sure, I can SSH into the server and
see the usage with ifconfig, or virsh as you say - but I can't allow clients
to login into the main server.

I need a way for a client to login to a PHP / MySQL based sytem, which can
show them traffic graphs for their VPS's, and OpenVZ works different from
Xen, so I can't even rely on the Xen stuff.

I'm looking for something similar to Cacti / MRTG - but something that can
graph traffic for each IP / VM on a server

How about the xentop command, you can use it in batch mode and it can
display network statistics. So you should be able to write simple
plugin for Cacti that parses it output.

humm... Cacti or mrtg would work fine if it targets the interface and 
the resources on the inside of the vm. for all purposes it should not 
matter if the machine is virtual or not.


Or am I missing something ?

[CentOS-virt] KVM + bridge + static ip address

[Raymond C. Rodgers]

Hi folks,
I've been reading through the list a bit, and also looked at the KVM 
How-To on the wiki (http://wiki.centos.org/HowTos/KVM ) but I still have 
a question. I haven't yet begun to set up KVM, so I haven't made any 
mistakes yet. :-)


My company recently rented a server on which CentOS 5.0 is installed, 
and my goal is to set up a virtualized instance of CentOS for a new 
employee to tinker and learn on before I let him have hands on the real 
server. What I want to do is set up CentOS in KVM, and assign it one of 
the unused IP addresses on the server so that he and I can access it 
without having to first connect to the real server. The wiki didn't 
really give me a good idea of how to accomplish this, and I haven't done 
a bridge before, so I wanted to check with the list to see if I could 
get some advice on how to accomplish this.


For demonstration purposes, lets say that the external IP address of 
the real server is 10.0.0.1, and I want the virtualized install to be 
found at 10.0.0.2. Can someone show me how to modify the kvm rules found 
on the wiki (and pasted below) to accomplish this?


Thanks!

set vifnam=xenname in the vif=[] statement and  you can give the interfaces
symbolic names that don't change every reboot (the snmp mib number still
changes, but the snmp name stays the same.  you need to setup cacti to
map  the names to numbers often. )

snmpd in the dom0 will then report for each interface as if the dom0 was a 
switch, and you can use cacti or mrtg or whatever to aggrigate interface 
counts.  cacti or mrtg or whatever will take care of dealing with reboots
resetting the counters.

Like any layer2 bridge, you need to be careful of your arp cache... if someone
poisions your arp cache, all traffic will go to all DomUs, messing up your
counter.   But I've had plenty of co-lo providers with that problem on 
physical switches, so maybe that is acceptable.

That said, at prgmr.com, I just run bandwidthd at the head of my network.
I hang bandwidthd off of a SPAN port attached to my uplink.The big problem
here is that it only supports ipv4.  the v6 traffic is free.  free!  but it
works with whatever virt tech you use as long as you trust the to/from IP
addresses, and as long as all your traffic is IPv4

[CentOS-virt] RE: VMs won't power on

[Richard Fairfield]

Because I was in a hurry, I had to move this project to a different OS.
I installed VMserver on Ubuntu,

where I had knew it would work. I'll come back to CentOS later.

 

But, for those that asked:

1) I was not running the Xen verion of the kernel.

2) The VMs that I was trying to start are good; they both worked on
other VMware Server installations.

 

Thanks to all who responded.

Subject: VMs won't power on

 

Hello -

 

I have installed the VMware-server-1.0.5-80187.i386.rpm package on a
CentOS 5.1 system. I then ran the vmware-config.pl program. I chose
mostly default answer, except that I did not choose the NAT option; I
saw no errors. 

I used the VMware Server Console to create a Red Hat Linux VM. I also
copied an externally created VM into the '/var/lib/vmware/Virtual
Machines/' directory. I cannot power-on either of these VMs. The VM's
console is blank for several minutes, after which the following message
appears in a pop-up window:

Unable to change virtual machine power state: The
"/usr/lib/vmware/bin/vmware-vmx" process did not start properly
Try running "/usr/lib/vmware/bin/vmware-vmx /var/lib/vmware/Virtual
Machines/Red Hat Linux/Red Hat Linux.vmx" from the command-line on the
server..

I tried running it from the command line, as the message suggests. That
just hangs forever. I don't see anything other than the above error
message in the /var/log/vmlog/vmware-serverd.log file.

I've tried rebooting, and uninstalling and reinstalling the VMware
Server software. I even tried installing from tar file, instead of the
RPM. Nothing changes.

I'm completely stuck. Can anyone help me with this?

When a vm won't boot, you can review the vmware.log in the vm's folder 
for diagnosis. Also, you can set debug on in the vmware-server-console 
interface to get extra information into the logfile above.

If you are both so new to this then simply virt-install a CentOS VM. It 
will work out of the box without using brctl and what else. If not already 
in use, switch to the xen kernel for this.

I'm more familiar with KVM than I am Xen; I've managed to get QEMU/KVM 
virtual machines up and running, I'm just concerned about the bridging 
angle. Although I haven't done any configuring yet, I'm not as sure of 
myself when it comes to Xen, and have only dabbled a bit.


That said, if Xen will let me accomplish this with minimum fuss, then 
I'll happily switch to that for this virtual box. Is there anything in 
particular I need to look out for with Xen?


Thanks,
Raymond

Re: [CentOS-virt] Installing guest OS on Xen 3

[white list]

If I comment the pygrub line I get the following error message.

[EMAIL PROTECTED] xen]# xm create -c vm02
Using config file "./vm02".
Error: HVM guest support is unavailable: is VT/AMD-V supported by your CPU
and enabled in your BIOS?



Please Help!
