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. >I haven't messed with it recently, but some of my docs on running >Gentoo on EC2 might be useful, since EC2 is ultimately running xen >guests.

Most of my write-ups were about the Amazon process (creating >disk images, configuring grub.cfg for Amazon's grub and device >numbering, etc). 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. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
