I have small VM environment, it has been running for 6 months and it all of a sudden became very very slow.
I have one server with two quad core processors and 48 gb ram.
7 persistent VM (windows 7, two Server 2012)
one raid 10 -15k drives
one raid 5 - 15k drives
Each VM has 4gb ram,
Not sure why or what to look for but the base server is slow and so are all of the VMs.
Checked basic system issues: disk space, what is running, performance via task manager and nothing seems to jump out.
I stopped each VM and had restated them. It took a while for them to start up and then the CPU is running at 100% via task manager within the VM. Not sure if this is a good indicator.
Any idea of where to look? Let me know if you need more info, thanks.
