Yes, you're right, but your calculation were also wrong. It's 512, not 1024.

Possibly it could, but it is not an available package on CentOS. I am

He shouldn't need to know the layout of his hdd :-) It's like reading
the raw sectors to view a wordprocessor document. Use libguestfs!

I got as far as mounting the first partition which is /boot. The second

Hi,
>> Another option is guestfish: http://libguestfs.org/
I have to migrate the image to a remote system because I don't have
all the tools there to run this. Do you know if guestfish requires a
kvm kernel and processor, or can it be done with an older processor?
When I try and mount the image,
Hi,
Did you try http://equivocation.org/node/107 ?

Yes, but doesn't work, because I believe it assumes the image is already of
type 'raw', which is the exact problem I'm having.
Thanks,

Still another is to add it as a additional disk to some
other virtual machine and get to it that way (which
may be what guestfish does internally - I've never
been sure).

Hi,
I have a 5GB kvm image that I created some time ago, and would like to
mount it on the host system to access it. I've located a few documents
online for how to do this, but it doesn't seem to work properly.
Can someone direct me to information on how to mount a qcow2 image as
