SQL Server Error in '/' Application.

We have upgraded our virtual environment from Hyper to VMWare. Both environments consist of a SAN and 2 host. We were able to successfully migrate all of our vm's with the exception of two of our SQL servers. One of the SQL server is apart of our SharePoint environment. After I shut the SQL server down in Hyper-V and power on the SQL server in VM and lauch our SharePoint site, I get the following error:

It looks like the dependent server is not there in vsphere environment.  Although I would recommend to reconfigure the permission.

The error occurs when the share-point farm administrator cannot connect to configuration database.

++ are you able to ping SharePoint frontend and application server from SQL server ?
++ does farm accounts have permission to confgiuration database.
++ Try to restart SQL host service and reboot Central admin and then front end server.

I am closing this ticket because the issue has been resolved. We discovered that this issue only occurs when we use live migration to move the vm.
