We have 3 Host DRS,HA enabled Cluster running Virtual Machines.
Today i had a problem with one VM that configured to run Multiple scheduled tasks for App enironment.
The problem is " VM is not responding on specific time " ( Like VM is Put my task on waiting for long time) on specific time.
But other times it works well, No constant High CPU, only sudden Spikes..
Here are the Configurations for that VM,
VM : Windows 2k3 ,3 vCPU , Memory 12 GB
CPU Limit : 13489 MHZ
Worst Cast Allocation : 3.49 GHZ
Share Value : 3000 ( Niormal)
I chaged to CPU Limit and shares:
CPU Limit : unlimited
Share Value : 4000 (Custom)
Worst Cast Allocation : 3.49 GHZ (Not changed)
please advise is this setting will work or this will create any Performace impact over the VM/Cluster.
Hence this is my first post and am newbie to this.
Need your Advise.
Were any other VM's having issues are this time?
What do the Event logs and monitoring software say whas happening on the guest at the time in question (windows side not VMware side)
What were these tasks, where memory intensive or CPU intensive or IO intensive or a mixture of all three?
So from what you are saying it seems that the issue is related to this particular VM. I would set up some perfmon checks on the guest (from with in the guest) and monitor.
the fact that no other guest machine is affected appears to rule out the VMware environment.
