The DSM images available in the packages above come from these Synology’s archives.

You can find here or here how to create a Virtual Synology with theses packages (Notice I have fine-tuned those, among others to put the disks in the right boot order for the DS3617xs).

Before importing a package in VMWare, you can update its Mac Address and its Serial to make them unique in your network (E.g.: if you duplicates the images). For that purpose, you need OSFMount, a tool able to update (read and write) the content of .img files.

Run OSFMount and open the disk image file “synoboot.img” (Do not mount it as Ram Drive):

“Select All” the partitions as virtual  disks and uncheck the flag “Read-only drive”:

Once opened, double-click on the first drive in the list to open it. It contains the settings to be customized in the file drive:\grub\grub.cfg. Edit that file to change the Serial (set sn) and the MAC address (set mac1):

A new MAC address can be generated using VMWare; via a Network Adapter > Advanced > Generate. Click on the button Generate a few times and copy the value in the file above (removing the various semicolons).

A new Serial can be generated on this site.

Once done with the edition, “Dismount All” the drives in OSFMount. You can now import the virtual machines in VMWare.

Et voilà.
