Re: [Xen-devel] fdisk hard drive image

So your config file looks like:
disk = ['file:/path/to/file,hda2,w']

Then in the guest you run:
# fdisk -l /dev/hda

And get "can't open /dev/hda"?

That's to be expected, since you're using a Xen "virtual" partition and there 
isn't a real hda behind it.

Should work as far as I know.

This should be:
disk = ['file:/img,hda,w']

otherwise the tools don't know what kind of backing you want for the VBD.

That should just work if the setup of /dev/loop3 worked OK.  Can you 
mount /dev/loop3 in dom0 OK?

Can you please post what errors you're getting from these attempts?

Cheers,
Mark
