Synology is a proprietary piece of software that is used for managing the companies NAS devices. The awesome thing about the Synology software is it is very light weight, uses next to no resources, can provide RAID support and manage several drives in a pool. If you are wanting the convenience of a NAS without the additional hardware, a convenient option for managing your files, remote file server etc. Synology might be an excellent fit. Though typically without purchasing said Synology device, this option wouldn’t be available, With the help of  a loader developed by some crafty individuals, we can enjoy Synology on our home server via a Proxmox VM.

Lets go ahead and get started with gathering the files needed for this install:

  • Juns Loader V1.04b here
  • DSM_DS918+_23824.pat here
  • Synology Assistant here

Now that we have those downloaded, lets jump into Proxmox and start a New VM

Use the following Options:

Name: Synology (or whatever you please)

Select: Do Not Use Any Media
Type: LInux
Version: 4X/3X/2.6 Kernal

Hard Disk
Bus/Device: Sata
Storage: local
Disk Size: 20GB
Format: QeMU image format (qcow1)

Sockets: 1
cores: 1
Type: Default (kvm64)

Use Fixed Size
Memory(MB): 2048

Bridged Mode
Model: Intel E1000

OK now we are done with the initial setup but we have a few steps we need to do lets assume you used the id “104” for this particular VM, in that case we want to move Juns Loader V1.04b (make sure it is titled “synoboot.img“) to the following directory:


Now with the image in its correct location we want to get to a command line via the shell, puTTy etc. and type the following:

qm importdisk 104 /var/lib/vz/images/104/synoboot.img local

You should see the following:

Now If we go to the Hardware page in the Proxmox gui we should see our now “Unused Disk” towards the bottom, click on that and change it to: Sata 1 and hit Ok.

Now jump to the Options Page:

change the following:
Boot Order: Disk ‘sata1’, CD-ROM, Network
SCSI Controller: Default (LSI 53C895A)

Back to the Hardware page
Add -> EFI Disk

Let’s go check The NETWORK Model one more time and ensure it is on Intel E1000, if not switch it back (I found mine to Change itself and give me issues).

Now one last Final Step, we have to insert an “Args” string into the config file, so open up a puTTy session logging in to your server as root and type the following:

cd /etc/pve/qemu-server/

We are now in a directory that contains the config files for all individual VM’s & Containers named 100.conf, 101.conf, 102.conf etc. so depending on what VM ID your Synology server has been (104 for this example) you will type the following:

nano 104.conf

We are now in the Editing Screen, press the enter key to move the arguments down a couple lines, and with your cursor on the top line enter the following line:

args: -device 'piix3-usb-uhci,addr=0x18' -drive 'id=synoboot,file=/var/lib/vz/images/104/synoboot.img,if=none,format=raw' -device 'usb-storage,id=synoboot,drive=synoboot'

Note that that should be all one continuous line, now we will save the file by pressing:

ctrl + o then Enter to confirm

Lastly we just need to exit with ctrl + x

We should be Set up and Ready to Go!

Start up the VM and We should be taken to a GRUB with a few Options, Select the First Option if it doesn’t just go forward automatically.

We will now be presented with a screen that asks us to visit, I have yet to ever see that actually work so this would be a good time to install the Synology Assistant if you haven’t already.

With the Synology Assistant open, it will begin to Search, if it doesn’t find anything the first time don’t fear just click on the search button.

when a User Agreement Licence window Pops up go ahead and agree and you should see your Synology install below, click on the result and it will load a browser window with the current IP and Port # (Take note of that) and let you begin the install.

  • This will bring you to the Welcome Page where you will click on Setup
  • Select Manual Install
  • Click Browse and Find the “DSM_DS918+_23824.pat” file we downloaded earlier
  • Let the installation complete
  • Choose a Server name & Credentials
  • Click Next
  • DSM Update & Maintenance (choose your preferences)
  • Setup QuickConnect (You can set this up or skip it)
  • Click Go!

Update: Your Synology server will advise you of the following system update DSM 6.2.2-24922 Update 3, Juns loader 1.04b is considered “Compatible” always update at your own risk. (I personally have updated without Issue)

Congratulations, you have completed the install and have Synology up and running! You can also check out my guide on Setting up an Automated Home Theater System with Synology here, also feel free to look up mapping Synology Shared Folders to Windows, or Mounting Synology Folder in Linux, Setting Up Raid etc.

Happy NASing!

Hello, does this process work? I am unable to locate the diskstation using the assistant program. Any hints?

    PhRoZeN CrEw · August 10, 2019 at 4:29 pm

    Yes as a matter of fact the process does work, it’s how I have mine set up. If using the Synology Assistant (Even with physical synology devices) After you open it up and it does it’s search, it never seems to display anything and you have to click on the search again and do it manually before it shows up, give that a shot and see if it might solve the issue.

      PhRoZeN CrEw · September 1, 2019 at 5:08 pm

      Please see the updated tutorial, the last step before starting the VM has been added, That should fix your issue, again though I can to scan twice before the licence agreement pulled up in the assistant and showed the server 🙂

chronaden · August 30, 2019 at 2:45 pm

Hi, i followed your guide to the letter, the loader boots and is pending you connect to the server via the Assistant, but it never shows up, no matter how long I wait and how many times I press “search”, I’ve tried and changing network interface, but no luck. Proxmox 5.2 with Unifi network gear. Loader 1.04b

    PhRoZeN CrEw · September 1, 2019 at 4:51 pm

    I went back over the tutorial step by step and it appears I have found the issue, I am missing a step in the guide. I sincerely apologize for the frustration and effort I am updating the Guide right now, You have to insert an args string into the config file.

Andy · September 4, 2019 at 7:57 pm


Everything is working great, the NAS is up and running. But I’m not sure what you mean with this step:
“Congratulations, you have completed the install and have Synology up and running, be sure to Remove the Disk we created earlier and set the Boot Options back to:”
-Which disk to remove? The sata 1 referencing synoboot.img?
– What should the Boot options be changed to? None of my options are working (sata0, cdrom, network). Or is the issue I should create volume from the 20GB disk from within DSM first before setting sata0 as boot?


    PhRoZeN CrEw · September 5, 2019 at 1:12 am

    Good Question… Not sure I almost think that might have been part of a previous posting and not even related to this page. Glad to hear you got everything up and running! Boot Order should still be Sata1, CD-Rom, Network 🙂

Hello, im currently trying to add the synoboot image into that directory.. however my image is not in my “local” storage location. How can i specify my other storage and find that location?

    PhRoZeN CrEw · September 19, 2019 at 7:03 am

    If I’m understanding you correctly you are using an additional disk for storage in which the VM is located on, in that case you would need to do the qm importdisk “path of VM’s Config File\synboot.img” “name of Disc” and you would simply refer to that location in the args statement referencing where the .img is located. The only problem is I have no clue if the VM’s config file is actually located on the “local” or if they put it on the additional drive you specified, and if so what directory that would be?

      Chandler Sharp · September 19, 2019 at 5:39 pm

      I was able to figure it out by adding the images options to local storage. then i could follow your guide. Im currently at the end but have been unable to find it using synology assistant. It doesnt show up on unifi controller either

        PhRoZeN CrEw · September 19, 2019 at 10:21 pm

        Did you add the arguments statement to the VM configuration file with the correct directory? It’s very important that that loader boots every time the VM starts

          Chandler · September 20, 2019 at 1:51 pm

          Yes i did add the arg statement and also changed the boot order. I do believe that is using the synoboot.img because i get the to page that says please go to however it seems like i never gets an IP address. I cant find it in my router or with synology assistant. using the NIC in a dell r610

          PhRoZeN CrEw · September 20, 2019 at 2:16 pm

          Interesting The Only thing I could suggest in too ensure the Network driver is E1000 as I have had that revert itself, with issues. Otherwise as there is very few people here I would check on this forum -> somone might be able to assist. I have gone through this guide twice now setting a VM up from start to finish step by step to ensure everything is in tact, so this is going to be something to do particularly with your setup.

Chandler · September 20, 2019 at 7:39 pm

No probelm i appreciate your help. Ive just done it successfully with a 6.1 loader. Id prefer the newer one but that just proves that it is something hardware specific of mine that doesnt like the 6.2 loader. Also i realized that there was another step on the message page.. the 6.2 loader just spun waiting and the 6.1 actually got to the “booting kernel” message.

Jasper · October 13, 2019 at 7:18 pm

Should this work with proxmox 6 as well?
I followed the tutorial but the assistant does not find the Synology server

    PhRoZeN CrEw · October 13, 2019 at 9:13 pm

    That Assistant Software Sucks, did you click “Search Again”? I Have never had the software find the server on the first run, and that goes for “Actual” synology Nas Servers. I assume it would work with version 6, though I have not tested that as I am currently still on 5. (Also be sure your adding those args to the config file, and what is posted is all one continuous line)

    Andy · October 14, 2019 at 1:59 pm

    I having the same issue on Proxmox 6, cannot find the dsm
