Hello, I'm a new baby to coLinux. Thanks for your wonderful job!
now, i have some trouble in creating disk image!
here is my steps:
 
first, I installed a xubuntu system in VirtualBox(my host OS is Windows7)
second, I turn off the Virtual machine, using VBoxManage.exe covert the "vdi" disk file to RAW format
third, I use dd coverting the RAW image with para "bs=512 skip=63"
 
could you tell me whether these steps has something wrong? And How to make rootfs image?
 
wish to hear from you !
 
Happy new year!
