For PV, grub is actually more work to get working. There is a config option for the commandline. |

I will send one of mine later today. |

Does EC2 actually provide PV guests? |
33 |
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. |
