[nflug] Routing Problem that I would love some input on

[James Wenzel]

I currently have a xen setup with ubuntu as guest OSes. It is a pain to configure as Dave said, but it is a breeze to maintain. As for the resources Xen will allow resources to be allocated to who is calling them. The hypervisor itself takes up very little system resources. Also with the dynamic allocations of resources Xen also allows for it to bubble over and grab more than the base limits for times when it is needed. If anything it is a pretty slick system that should be checked out. With the Xen implementation that I use there is no gui, or Xwindows on any of the machines, reducing resource requirements.

sorry wrong..  GSX (VMWare Server) is a user level
app, and it's guest OS's suffer rather severely
(15-50%)for I/O and cpu vs something expensive like
ESX server (an (almost) bare metal hypervisor) or Xen
(free for the express version),   I'm working with Xen
at work, and have to say it's REALLY cool,  but like
anything else, it can be a bitch  getting some guests
installed under the commercialized Xen is tricky as
they only support Redhat and centos guests, and others
are harder to get working, and unsupported.
