From a search the closest I can find is some sort of software that provides routing functionality http://www.vyatta.com/index.php Is that it ?> My problem is i have installed '4' virtual machines. > each virtual machine have 256Mb RAM. > But i am not able to run 4 virtual machines at a time.What is stopping you? is there an error? If so what error? nate (not familiar with Xen myself, I prefer vmware)

Vyatta is an open source full-featured router/firewall/vpn solution based on Debian. It can be installed on a physical computer or virtualized. Especially in a virtualized environment, Vyatta allows one to easily segregate network segments. Resource requirements can be very low depending on the level of traffic and features enabled. I currently use it as my primary home router for my static PPPoE AT&T DSL. I also use it to provide inter-VLAN routing. At my previous employment, I used it for inter-VLAN routing - segments for VoIP, LAN, and DMZ. It worked very well and never had a hiccup. Best of all, there is no fee for the community edition, with a new version about every 6 months. There's a subscription service if you want technical support and timely updates. BTW, I don't work for Vyatta, just a happy user of their product. Here are the technical specs from their website: HARDWARE SUPPORT ? 32-bit x86 processors ?

What CentOS product are you using for these virtual machines? Are you using xen or something else? mhr
