http://www.plan9.bell-labs.com/wiki/plan9/installing_in_Xen_3.0 This is a paravirtualised kernel which runs on xen; I've used it on an AWS server with reasonable success. With modern intel hardware, it's also possible to run normal native plan 9 on Xen. > for my Plan9 CPU/Auth/File server. Another candidate > is raspberry pi. The pi makes an excellent terminal but I wouldn't use one as a file server. The only way to attach a local disk is via usb, and the usb interface is not the strongest point of the Broadcom SoC. It will be slow and probably unreliable.
