Xen and Multiple Networks

Mon Jan 14 10:55:00 2008

Last Friday I asked a question about how to set up a network in Xen with a machine attached between a public and private network, like you might use in a firewall or load balancing situation. I want to be able to mimic real world networking situation in Xen for experimentation and modeling purposes. There were numerous replies and I'm grateful for all the help. In the end, Steve Fulling (he's not as pointy haired as you though) came up with a pretty simple solution. To use virt-install to create a bridged, public machine, you'd do something like this:

Xen, VLANs, and Load Balancing

Fri Jan 11 14:01:00 2008

I want to create a setup on XEN that has one or more machines load balancing for a number of other machines on a private network. This diagram shows roughly what I'm thinking: The idea is that some machines will be connected to both the public network and the private LAN and other machines will only be connected to the VLAN. This offers some security benefits and reduces the number of public IP numbers I need. The catch is I want to do this all virtually. Does anyone know of the recommended way to do this with XEN? I

Enomalism and Xen

Thu Dec 13 07:14:00 2007

I'm looking for a management console for Xen (besides the command line). I'd looked into this months and months ago and concluded that when the time came, I'd try Enomalism, but after some initial experiments I'm no longer sure. Any advice? Let me know what you use for managing the Xen hypervisor and why.

Virtual Appliances

Sat Mar 10 12:05:00 2007

I spent a little time today playing around with a virtual appliance (VA) from VirtualAppliances.net. They have LAMP, Tomcat, Cacti, MySQL, PostgreSQL, and HTTTP server virtual appliances that you can download and run inside a variety of virtualization environments, including VMWare and XEN. I downloaded the LAMP stack VA and it booted in VMWare Fusion on my MacBook Pro. The VA uses DHCP to get its network address (there's no option or static IP numbers at boot time) and the boot screen gives the relevant URLs for the admin console. There's no way to log in--you use the management

Routing Around VMWare

Wed Jan 3 12:47:00 2007

Today Terry Wilcox, my grad students working on virtualization informed me that he had Xen installed and working on our virtualization testbed (two dell 6650's with 4 CPUs and 16Gb of RAM). Working means that he can transfer running instances from one box to the other. We have been doing a lot of performance studies of VMWare's ESX, but switched to Xen for the next part of Terry's research. The reason isn't that we wanted some infrastructural diversity, although that's not all bad. The reason is that we had reason to fear that VMWare might hinder the publication of
