Prerequisites to Add Microsoft Hyper-V
Prerequisites to install Vembu Integration Service (VIS) on Microsoft Hyper-V
To backup the virtual machines in Hyper-V, Vembu BDR will automatically install Vembu Integration Service (VIS) in the Hyper-V Server when it is added for backup. Make sure the following prerequisites are met for Vembu BDR to successfully install the VIS on the target Hyper-V Server.
Access privilege for Microsoft Hyper-V (Standalone, Cluster, and SMB Server)
Make sure the credential you use to add the Hyper-V Server (Target Host) for backup has any one of the following privileges:
Domain administrator
Administrator
User with administrator privilege
Access privilege in the BDR Backup Server host
In the BDR Backup Server host, make sure the Windows service ‘Vembu BDR Backup Server for Virtual Physical Workloads’ runs in an administrator user account.
Press the ‘Win + R’ keys on your keyboard to open the Run window. Then, type ‘services.msc’ and click OK.
Right-click on the service ‘Vembu BDR Backup Server for Virtual Physical Workloads’ and then click ‘Properties’.
Navigate to the ‘Logon’ tab. Click on the ‘This account’ radio button. Provide the administrator user privilege: username (Format: .\username) and password. Then click OK.
Then stop and restart the service for updating the new logon.
Access to the folder - “Admin$” in the target Hyper-V host
Make sure the BDR Backup Server host has access to the “Admin$” folder of the target host: Type \\IP Address of target host\admin$ in ‘Run’ and click OK.
If the UNC path is accessible, move to the next Prerequisite.
If the UNC path is not accessible, perform the steps below:
Step 1: Add the below-mentioned Inbound rule in the Hyper-V target host, to make sure your firewall doesn’t block the Windows Management Instrumentation function.
Open Control Panel and navigate to System and Security -> Windows Firewall -> Advanced Settings.
On the Windows Firewall with Advanced Security dialog box, click the ‘Inbound Rules’ option on the left.
Under the Actions pane on the right, click ‘New Rule’.
On the New Inbound Rule Wizard, choose the option ‘Predefined’as Rule Type.
Then, select the ‘Remote Service Management’ rule from the dropdown, and click ‘Next’.
Rules under the selected type will be listed, proceed with the option ‘Enabled by Default’ and click Next.
On the Action page, choose the option ‘Allow the Connection’ and then click ‘Finish’.
Step 2: Make sure the following services are running in the target host:
Press the ‘Win + R’ keys on your keyboard to open the 'Run' window. Then, type ‘services.msc’ and click OK.
Check the services ‘Server Service’ and ‘Windows Remote Management (WS-management)’ and confirm if their status is running.
Once the above two steps are performed, in the BDR Backup Server host type ‘\\IP Address of target host\admin$’ in 'Run' and click OK. If you are able to access the Admin$ share, proceed with the next step.
Access to Windows Management Instrumentation
Add the below-mentioned Inbound rule in the target Hyper-V host, to make sure your firewall doesn’t block the remote connection.
Open Control Panel and navigate to System and Security -> Windows Firewall -> Advanced Settings.
On the Windows Firewall with Advanced Security dialog box, click the ‘ Inbound Rules’ option on the left.
Under the Actions pane on the right, click ‘New Rule’.
On the New Inbound Rule Wizard, choose the option ‘Predefined’ as Rule Type.
Then, select the ‘ Windows Management Instrumentation ’ Rule from the dropdown, and click ‘Next’.
Rules under the selected type will be listed, proceed with the option 'Enabled by Default' and click Next.
On the Action page, choose the option ‘Allow the Connection’ and then click Finish.
Make sure the following service is running in the target host:
Press the ‘Win + R’ keys on your keyboard to open the 'Run' window. Then, type ‘ services.msc’ and click OK.
Check the service ‘Windows Management Instrumentation’ and confirm if its status is running.
Access to Remote Registry
In the target Hyper-V host, press the ‘Win + R’ keys on your keyboard to open the 'Run' window. Then, type ‘services.msc’ and click OK.
Check the service ‘Remote Registry’ and make sure its status is running.
WBEMTest Verification
Once the above-mentioned prerequisites are done, perform the WBEMTest to test remote connectivity to the target host from the BDR Backup Server host.
On the BDR Backup Server host, Press the ‘Win + R’ keys on your keyboard to open the 'Run' window. Then, type ‘wbemtest’ and click OK
In the namespace field: Enter the following: \IP Address of target host\root\cimv2
Under the credential section: Enter the Username and Password of the target host and click ‘Connect’.
If any error occurs on the WBEMTest, recheck the prerequisites.
Once the WBEMTest is successful, you can add the target Hyper-V Server for backup in BDR Backup Server.
Note: For Hyper-V Cluster, Vembu Integration Service (VIS) will be installed on all nodes of the cluster. Hence ensure that the prerequisites are met for all nodes.
