Virtual Machine is slow

SO looking at a system that I just inherited.  The users say it is slow. (See attached)  The HOST CPU is showing at consumed and also the HOST memory.  What can I do here?

I have had this happen a few times and a VM reboot usually fixes that.

I assume you have a SQL database on that VM as they tend to eat up all available resources after being powered on for a while.

I have had a problem with this occurring after a power outage and my UPS's run out of juice. When the VM Host auto-starts and auto-starts the VM, the VMs will sometimes have 100% CPU and Memory usage - causing slow performance. 100% of the time I gracefully power down the VM, gracefully power off the VM Host and then gracefully power them up, making sure I give the Host at least 60-90 seconds of run time after a full boot up before powering on the VM.

Try that first, your problem should go away if related to that 'bug'.

What is the Host Server?

What is the specification, memory and CPU?

What is the VM?

and what has been defined for the VM?

No, no SQL database and I did a power down previously. I believe I am not allocating enough resources to this VM?

Did you power off the VM and then the Host? Then gracefully power them both on? Restarting just the VMs did not work for me, I had to do the Host too.
 
You can always rule out the resources by increasing them. 4gig RAM is low for a Terminal Server so I would bump to 12-16gigs if you can. Adding an additional vCPU would always help if you are overloading your CPU.

Hmmm. Wouldn't cause an issue to increase after creation of the VM?

I'm sure of the procedure to this

I'm not sure of the procedure is what I meant to say.

I have done that a few times without issue but hanccocka could probably advise on that better than I. I believe he has Articles with step by step instruction on those processes.

You showed us the Resource Allocation. Click on the next tab and show us the Performance data.

If you have a Windows 2012 Application Server (e.g. Terminal Server), how many users are using it?

YOu will probably need at least 2 vCPU allocated, and a minimum of 8GB.

But it will depend on what Host Resources you have available?

So what specificiation is the host server, how much ram and cpu, what is the storage? e.g. RAID type, number of disks, SATA or SAS for the ESXi datastore?
