Re: [Xen-users] pygrub error booting iso
ok, some other things that are weird:
hdc ends up on xvda
hdd ends up on xvde
Huh?
I don't know whether this is pygrub or Xen that's causing the problems.

You mean like this?:
disk = [
'file:/tmp/ubuntu/10.04/ubuntu-10.04-server-amd64.iso,hdc:cdrom,r',
"tap:aio:/var/lib/xen/images/CLOUD-CC-1.img,xvda,w"
]
Gives me the exact same result:
Error: Boot loader didn't return any data!
I've verified the paths to the kernel and ramdisk. It's weird because I did this some time ago without any problem. But now it doesn't work. Maybe because I updated to Xen 4.0.0-rc8? Pygrub says version 0.6 inside it.

Why not just use file: and iso path? I don't see any benefit to
another layer of abstraction
