My only experience is with Amazon, which doesn't give you any control over the host xen. It just runs grub with a grub.cfg you provide if you want to run your own kernel (unless that has changed). > > Does EC2 actually provide PV guests? > With PV, the guest knows it's a guest and communicates with Xen. Non-PV has an emulation layer (qemu) running on the host that hides the virtualisation from the guest. > Special drivers on the guest can help with performance, but isn't necessary to get it to work. I believe that EC2 ONLY provides PV guests. I don't believe it will do full virtualization for linux guests. They do provide windows guests, and I'm not sure of the details of how that is done. If you want to run a linux guest you either use one of their kernels, or you can run your own as long as it supports Xen PV. -- Rich
