How to Convert an ESXi VM into an Hyperion VM

Written By Christian Castagna (Administrator)

Updated at October 29th, 2025

→ Applies to: Hyperion 9.x and above

PREREQUISITES
- Make sure the virtual machine is properly shut down before starting the conversion process.
- Verify that the version of the virtual machine you intend to convert to Syneto Hyperion is compatible (as shown in the table below). If the version is not listed, the conversion will not work properly.

IMPORTANT
Make sure the VM in ESXi is not configured with “Enable UEFI Secure Boot”.
Go to [ Advanced → Boot Options → Enable UEFI Secure Boot ] and make sure the option is unchecked.

 

Operating System

Supported Versions

ALT Linux From version 9
CentOS From version 4 to version 10
Debian From version 6
Fedora Linux All
Microsoft Windows From Windows XP to Windows 11 (Windows Server up to 2025)
openSUSE From version 10
Oracle Linux All
Red Hat Enterprise Linux From version 4 to version 10
Scientific Linux From version 4 to version 7

SUSE Linux Enterprise Server

From version 10

Ubuntu

From version 10.04


NOTE
Even if the conversion fails due to an unsupported version, you can still install that OS version on Syneto Hyperion as a new VM. In this case, the VM will function properly.

 

Step 1. Login to SynetoOS GUI

https://<your_ip_address_or_hostname>

 

Step 2. From Virtualization menu, click on Hypervisors

 

Step 3. Select the VMware ESXi VM you want to convert into a Syneto Hyperion VM

 

Step 4. In the top right corner, click on the three dots and then on Convert to Hyperion

The system will create a new VM (the converted VM) with the same name, without the UNREGISTERED icon.

 

Step 5. Select the VM you want to register into a Hyperion VM

 

Step 6. In the top right corner, click on the three dots and then on Register

 

Step 7. Select Register on 172.16.254.1, then click Register

 

Step 8 (optional). Power-on the converted Hyperion VM

At the first power on, the system will install the VirtIO drivers. Several reboots of the guest VM may occur during the driver installation.
