I can believe that. My only experience is with Amazon, which doesn't |
| 7 |
give you any control over the host xen. It just runs grub with a |
| 8 |
grub.cfg you provide if you want to run your own kernel (unless that |
| 9 |
has changed). |

I believe that EC2 ONLY provides PV guests. I don't believe it will |
| 17 |
do full virtualization for linux guests. They do provide windows |
| 18 |
guests, and I'm not sure of the details of how that is done. If you |
| 19 |
want to run a linux guest you either use one of their kernels, or you |
| 20 |
can run your own as long as it supports Xen PV. |
