We have got an ubuntu 14.04 LTS server with XEN software installed. Everything worked fine untill a day ago a Windows server stopped working (Windows server 2012) Now it's shuts down every 30 minutes or so. The server is very important as it is a production server.
The server gives an error which tells us that the power has been shut down.. But the Ubuntu log files do not provide any information.
Any help is appreciated at this point.
Cheers!
