→ Applies to: SynetoOS 6.x

By default, SynetoOS 5 is not automatically connected to the local VMware ESXi hypervisor. The connection must be manually performed, creating a custom ESXi user with the same root permissions.

The connection to the local ESXi hypervisor is always performed through the internel IP address 172.16.254.1.

 

Create a custom ESXi user

 

Step 1. Create a new user in VMware ESXi, to be used exclusively by SynetoOS

The username must be unique.
A suggested format could be: “syn-<8-random-numbers>” (e.g. syn-47226178)

 

Step 2. Assign the newly created user the administrator role

 

Connect to the local hypervisor

 

Step 1. Login to SynetoOS GUI

https://<your_ip_address_or_hostname>

 

Step 2. From Virtualization menu, click on Hypervisors

 

Step 3. Click on Add hypervisor button

 

Step 4. Fill in the required fields to add an external VMware ESXi and click the Add button

Address: to connect to the local hypervisor (running on the same appliance) use the IP address 172.16.254.1.
Username: the username previously created
Password: the password previously assigned
