Hello everyone,

This is my very first post. I am having an issue with virtual machines performance after I upgraded VE to the latest version, before that, everything was working very smooth. My virtual environment is very simple, just 5 windows 11 virtual machines using local storage. The host has plenty of memory RAM (384GB) so each VM has 32GB installed.
Yesterday, right after the upgrade, I noticed that all VMs were really slow, and the Disk utilization was at 100%. After a few minutes all machines were frozen and i was not able to do anything other than stop the VM.

I have been looking for information about this and I cannot find anything that can put me in the right path here. Any help about this issue will be high appreciated.

Thank you,

SpeednetUSA.
