To run virtual machines on your Synology NAS, you need to have at least 8 GB or 16 GB (or more) memory installed, depending on your requirements. Then, you can install and use the official Virtual Machine Manager app to create and manage your virtual machines from the Synology Web GUI.
In this article, I will show you how to set up virtualization on your Synology NAS and create a Windows 10 and an Ubuntu 20.04 LTS virtual machine on your Synology NAS. I will be using the Synology NAS model DS1821+ for the demonstrations. So, let’s get started!
Copying ISO Image to Synology NAS Share:
First, you need to copy the ISO image files (of the operating systems you want to install on your Synology NAS virtual machines) to the Synology NAS.
You can upload ISO image files from the Synology Web GUI using the File Station app. You can also connect to your Synology shares from Windows or Linux and copy the ISO image to your share.
In this article, I will copy the ISO image from my computer to a share of my Synology NAS.
To access your Synology NAS shares, you need to know the IP address of your Synology NAS. You can find it from the Synology Web GUI. As you can see, the IP address of my Synology NAS is 192.168.0.110. It will be different for you. So, make sure to replace it with yours from now on.
From Windows 10 operating system, navigate to \\192.168.0.110 from the File Explorer app to access the Synology NAS shares.
From Linux operating system, navigate to smb://192.168.0.110 from any file manager app to access the shares on your Synology NAS.
As you can see, the Synology NAS shares are listed on my Debian GNU/Linux operating system.
Now, copy the ISO image files to one of your Synology NAS shares.
I have copied the Windows 10, KDE Neon, and Ubuntu 20.04 LTS ISO images on my Synology NAS share share1.

Taking Snapshots of the Virtual Machine:
You can save the state of a virtual machine by taking a snapshot of it from the Virtual Machine Manager app. Before you attempt to do experiments on your virtual machines that may break the operating system or may remove important files, you can take snapshots of them. If anything breaks after the experiments, you can restore the virtual machines to their previous state (where you took the snapshot) and get the virtual machines up and running again.
To show you how to take snapshots and restore virtual machines from snapshots, I have prepared a simple example.
On my Ubuntu 20.04 LTS virtual machine vm1-ubuntu20, I have created a helloworld/ directory and a main.c file, as you can see in the screenshot below.
Let’s take a snapshot of the vm1-ubuntu20 virtual machine while this directory is available in the virtual machine.
Before you take a snapshot of the virtual machine, you must power off or shut it down.
To shut down the Ubuntu 20.04 LTS virtual machine vm1-ubuntu20, run the following command:
The virtual machine vm1-ubuntu20 should be Powered off, as you can see in the screenshot below.
To take a snapshot of the current state of the vm1-ubuntu20 virtual machine, select the vm1-ubuntu20, click on Action > Take a Snapshot, as shown in the screenshot below.
Type in a description of the snapshot and click on OK.
A snapshot of the vm1-ubuntu20 virtual machine should be taken.
To list the snapshots you have taken of a virtual machine, select the virtual machine and click on Action > Snapshot List, as shown in the screenshot below.
The snapshots you’ve taken of that virtual machine should be listed, as you can see in the screenshot below.
Restoring Virtual Machine from Snapshots:
If you have accidentally corrupted the operating system of your virtual machine or removed some important files from the virtual machine, you can restore them from snapshots.
Let’s see how to do it.
First, select the vm1-ubuntu20 virtual machine and click on Power on to power on the vm1-ubuntu20.
The vm1-ubuntu20 virtual machine should be Running. To connect to the display of the vm1-ubuntu20, select the virtual machine and click on Connect, as shown in the screenshot below.
Once you’re connected to the display of the virtual machine, open a Terminal and run the following command to delete the helloworld/ directory:
The helloworld/ directory is removed from the HOME directory, as you can see in the screenshot below.
Now, shutdown the virtual machine with the following command:
As you can see, the virtual machine vm1-ubuntu20 is Powered off.
Now, let’s say, you want to get the helloworld/ directory back. As we had taken a snapshot when we had the helloworld/ directory on the virtual machine vm1-ubuntu20, we can just restore it from the snapshot we have taken.
To restore the virtual machine vm1-ubuntu20 from a snapshot, select the virtual machine and click on Action > Snapshot List, as marked in the screenshot below.
Now, select the snapshot you want to restore to and click on Action.
Then, click on Restore to this snapshot.
If you want to take a snapshot of the current state of the virtual machine before restoring from your selected snapshot, then check Take a snapshot before restoring the virtual machine checkbox, as marked in the screenshot below.
I am not going to take a snapshot of the current state of the virtual machine before restoring the virtual machine from a snapshot. So, I will leave the Take a snapshot before restoring the virtual machine checkbox unchecked.
Once you’re ready, click on OK.
Now, type in the login password of your Synology Web GUI and check I understand my data will be permanently deleted and unrecoverable checkbox.
Once you’re done, click on Submit to confirm the restore operation.
The virtual machine vm1-ubuntu20 should be restored from a snapshot.
Now, select the virtual machine vm1-ubuntu20 and click on Power on.
Once the virtual machine vm1-ubuntu20 is running, click on Connect.
Once you’re connected to the display of the virtual machine, you should see that the helloworld/ directory is restored.
So, this is how you restore a virtual machine from a snapshot.
Sharing Virtual Machines:
You can share a virtual machine running on your Synology NAS with other people.
To share a virtual machine (let’s say, vm1-ubuntu20), select the virtual machine and click on Action > Create share link, as marked in the screenshot below.
The link where the virtual machine will be available should be displayed, as you can see in the screenshot below.
You can password protect the virtual machine if you want. So, when other people try to access the virtual machine using the shared link, they will be asked to type in a password.
To password protect a shared virtual machine, check Enable secure sharing checkbox and type in a share password, as shown in the screenshot below.
You can also set a validity period for the shared virtual machine. Once the validity period is over, the link will be removed automatically.
To set a validity period for the shared virtual machine, click on Validity period, as marked in the screenshot below.
You can set different validity period settings from here.
Set up start time: If you set a start time, then the link will be accessible after this time.
