All
We have a windows server 2012 as a hyper v host and 2 VM S SBS 2011 and windows 7 VM
Since this Tuesday the CPU usage is a constant 100% on both VMs and since backups were failing due to high cpu usage rebooted the SBS 2011 server. But even after a reboot/shutdown SBS is at a constant 100% usage
We disabled all non MS services, disabled Exchange, SQL and memory hungry services but the CPU usage is at a 100%.The time it goes down is when we stop all MS /NON MSservices except bare minimal services which needs to run the SBS properly
Even with this the moment we open up a MMC console , open up an application on the server the cpu goes to 10% and remains for a long time and then goes down again
But with all SBS services running it never happens and stays at a 100% even after acouple of hours
Hyper V integration services are up-to-date
Any advice is greatly appreciated.
Thanks
Dhanushka
