Hello Sadique,

ok, I understand the security motivation.
With Linux really has no problem in running as domU, but I made some tests with win2003 on xen and noted that free vmware server is faster. So, I'm thinking about use vmware. I really would like to use Xen, because it is real free software and I like so, but I must to deliver best performance to my customer.

I read about virtualization and para-virtualization. As I understood, the full virtualization that Xen does with Windows is not yet so fast, because it lacks free PV drivers. Is there any optimization to try?

Currently none. Xen Enterprise has PV drivers for windows, but you have to purchase that from Citrix to use that.

There is a work in progress to develop GPLed PV drivers for windows by the community, but I don't know its current status. Till the time those drivers are available, the performance may not that much impressive, but I think it should be ok while comparing with VMware since VMware is another beast in crumbling performance.


I'm already running win2003 on a separate partition (/dev/sda6, a sata raid1 device). I use debian etch and xen 3.0 from debian repositories.

Thank you!

Is it a good way to run common network services on dom0 (proxy-cache, dababase), beyond manage domU's ?

As far as security is concerned,  NO. Have them on domus
