Setup DSM 6.2.2 in a Virtual Synology DS918+ using VMWare

Here is a step by step "How-To create a Virtual Machine to emulate a DS918+ running DSM 6.2.2" using VMWare and Xpenology

Xpenology is a bootloader for Synology’s operating system which is called DSM. It can be used to setup DSM on a PC or in a Virtual Machine like VirtualBox or VMWare.

I am using VMWare 15. But any version from VMWare 11 should work.


1: Download and unzip this package, containing:

  • the configuration of the virtual machine (dsm.ovf, dsm.vmx, disk.vmdk and synoboot.vmdk),
  • the xpenology boot file for DS918+ (synoboot.img) and
  • the image of the DSM 6.2.2 for DS198+ (DSM_DS918+_24922.pat)

2: Open VMWare Workstation. If you never configured the default location where you want to create your Virtual Machines, press CTRL-P to open the “Preferences” panel. There, set this default location (I am using D:\VMWare).

3: Go next to "Windows Explorer", in the folder where you have unzipped the package, and double click dsm.ovf. This is going to import the VM into VMWare. Type a name for the new virtual machine (I am using DSM918 6.2.2) and click “Import”.

4: Here is the outcome to the importation. You can now click on “Power on this virtual machine”. If you want, you may also first increase the Memory, the Processors or the size of the SCSI Hard Disk (Do not touch the SATA Hard Disk which contains the boot loader).

5: As soon as you have run the VM, click into hit to let it capture the keyboard, and press the “down arrow” to select the loader for “VMWARE/ESXI” (attention, you don’t have a lot of time to start the selection). Press next Enter and it will boot.

6: Open the “Synology Assistant”, which is more efficient than the page to find your VM, and after 1 minute click on “Search”. If you didn’t wait long enough, you will see an Error message (In such a case, click Search “Again”. I never had to do this more than 3 times).

7: Finally, the Assistant will find your VM. A webpage should automatically open (Otherwise, right click on the VM and select “Install”). Click on “Set up” in that page.

8: Click next on the link “Manual Install”.

9: Click on Browse to select the image of the DSM 6.2.2 for DS918+ and Select the file “DSM_DS918+_24922.pat” in the folder where you unzipped the package downloaded here previously.

10: Finally, click on “Install Now” and confirm that the installation can override the disk… it’s the virtual SCSI Hard Disk member of the VM. No worry ;)

11: The installation will take a few minutes

12: Once the installation complete, you will see in the VMWare Workstation that the VM is rebooting. On the installation page, you see a countdown. If you want to check the status of the VM, you can go back to the Synology Assistant and Click Search. You should see that it’s restarting, installing patches, reconnecting and finally ready. At that moment, you can select the VM and click Connect.

13: You will now be able to login into the VM and configure it.

14: It’s now time to use the SCSI Hard Disk to create a first Volume. Open the DSM Main Menu and start the Storage Manager.

15: Go to Volume and click Create. Select the HDD of 20GB, etc...

16: You have now a brand new DS918+ with the DSM 6.2.2-24922 Update 3.

17: Now, you can upgrade the VM to your version of VMWare. Shutdown the DSM Properly (via the menu on the Buddy Icon in the top-right corner). The VM will soon stop.

18: Once the VM stopped, upgrade it by clicking on “Upgrade this virtual machine”.

Et voilà !

  1. Great article. I use vmware fusion instead of Workstation and it works great. Gives me the opportunity to try some different configurations and apps without touching my Synology.

    • I have an Ivy bridge I'm wanting to try this on - what creates the restriction? Is it an issue with VMWare or is there a CPU feature missing in older CPUs that it requires?

  2. Hi
    Im excited to get started with this project. I am familiar with Xpenology (bare metal) but have no experience with VM. So, I have a question from the start; Can I use the free version of VMWare (I'm presuming that Player is the free version) or do I need Pro?

    Thanks for the effort on this. The "package" is particularly nice!


  3. Hi,
    I am using VMWare Fusion v11, does anyone know why I am stuggling to install the DSM OS?

    Failed to format disk. (35)

  4. I somehow can't find the NAS with synology assistant or through web browser. There are no error with the import part either. I'm really confuse.

    • It can take minutes... I presumed you clicked on the "Search" several times to 'double check' ?

      Synology Assistant is using UDP ports 9999, 9998, 9997. If you know the IP address of your VM, you can test those ports 'manually' using netcat (Ex. on linux: nc -v -u -z -w 3 9997-9999). Netcat will reports which ports does not respond. But I am 99.9% sure the Assistant with not fail to detect the ports if they are active. Possibly, those ports are blocked by our local firewall ? Temporarily disable it or google for "VMWare ports blocked by windows firewall". If nothing prevent the assistant to contact those ports, then the VM is not working and it's really difficult for me to guess why.

  5. I think I have a problem on my vmware workstation 16 I not know whats happens but I never found with synology assistant It stop works I have reinstall, I make same process on VirtualBox and works.

  6. Well done ! Thank you !

    Followed the steps and it also works on esxi 7.0 ! For those who what to ran it on esxi and allow dsm to manage the disks itself either use a dedicated SATA controller and passthrough the controller to esxi or use raw disk mapping as instructed here: , the disavantage for the later is that it cannot use tHDD SMART function. The advantage for both is that you can plug out the disks from the esxi machine and throw them into a real synology nas and should work.

    Before finding your explanations I tried to set it up from scratch, but I had troubles creating a working vmdk from the xpenology bldr image. Please could you tell me which tool you've used to create the vmdk ?

  7. Works great in Workstation 15 Pro. I tried to implement a second instance but seems that the MAC address of the vNIC is hardcoded. Both instances of Xpenology present themselves with the same MAC addr. Is there a way to change the MAC address ? Even if i generate a new MAC addr in workstation, the instance still presents itself with the same MAC addr. Thanks.

  8. I can't import these files into VirtualBox hence I am creating from scratch. What is the MAC address for the NIC used?
