Re: [Cotson-users] Internet Connection in COTSon

[Roberto G. <gi...@di...>]

Assuming that you just want to update your image once, you may want to use
something like qemu+kvm (which is faster than current SimNow) to modify
your disk-image once:

- Create your image for qemu. Install everything you need there.
- Additionally, you may want to install the xget/xput utilities
from data/cotson-guest-tools.iso

Then:

[I repost below some older info that I had internally, but there could be
smarter ways to do the same]

-  Use Simnow's disktool to create a disk image of exactly the same size of
the disk you set up for the virtual-os install (you name it
disktool_image_to_trash.hdd)
-  Copy the first 512 bytes from disktool_image_to_trash.hdd to
my_final_image.hdd using
  $ dd if=disktool_image_to_trash.hdd of=my_final_image.hdd bs=512 count=1
  $ rm disktool_image_to_trash.hdd # we can delete it now
-  Convert your disk image using qemu-img to the raw format (it becomes
my_favourite_os_disk.raw)
-  Append the contents of the my_favourite_os_disk.raw file into
my_final_image.hdd
  $ dd if=my_favourite_os_disk.raw of=my_final_image.hdd bs=512 seek=1
-  Now you can boot Simnow using my_final_image.hdd (hopefully).


Hope it helps.
Roberto.
