VirtualBox command-line interface (VBoxManage) provides an easy way to convert raw disk image to the VDI/VMDK format and otherwise.

Let's assume that we have raw image of the sdb device:

$ sudo dd if=/dev/sdb of=./sdb.raw

To use it with VirtualBox we need to convert it to the VDI format:

$ VBoxManage convertdd sdb.raw sdb.vdi --format VDI

lubry

qemu-img convert -O vdi gnome.qcow2 gnome.vdi


#if its a raw image then:
VBoxManage convertdd opnstk.raw VBox.vdi --format VDI

1. First get to the existing directory
   $ cd my/folder/

2. Now start a new git repository
   $ git init

3. Identify if the current elements on the directory are needed or not and add them to the .gitignore file. When ready...
   $ vim .gitignore

4. When ready create the first commit on the server

lubry

$ git pull origin master //run this first, then
$ git push origin master


hint: Updates were rejected because the remote contains work that you do hint: not have locally. This is usually caused by another repository pushing hint: to the same ref. You may want to first integrate the remote changes hint: (e.g., 'git pull ...') before pushing again. hint: See the 'Note about fast-forwards' in 'git push --help' for details.
