Re: [Xen-users] Load Balancing

Hi,

This has nothing to do with XEN, but you can use keepalived. Maybe you could even run keepalive on your dom0's ...
Quite simple to configure, and good results with it. Might be difficult to debug if you do not have full understanding of network layer 2 & 3. With such a product, you must be careful if you have STP activated on your switches. You must deactivate STP on the used ports of your switches, and ensure that they accept gratuitous ARP quickly.

Regards,

Subject: [Xen-users] Load Balancing

Hello Here,

Here is the schema I want to have. Sorry for my bad ascii work ;)

|----------------------------------|                  
|----------------------------------|                                    
    
|SERVER1                         |                  |SERVER2            
             |
|                                          |                  |        
                                  |
|XEN BASED                     |                  |XEN BASED            
         |
|SYSTEM                           |                  |SYSTEM            
               |
|                                          |                  |        
                                  |
| WIN 2008 SBS GUEST  |                  | WIN 2008 SBS GUEST  |
| WIN 2008 PRO GUEST |                  | WIN 2008 PRO GUEST|
|----------------------------------|                  
|----------------------------------|


What I want to is making load balancing between server1 and server2. So
I need to "synchronize" the two WIN 2008 SBS and the two WIN 2008 Pro.
=> if everything goes well, I make load balancing. If one of my physical
server is down, I keep one up to avoid downtime.

Is someone know if there is a way to do that? Is it possible? I heard
about LBVM. Is it the solution? Is it the only one?

Thank you a lot,
nm
