May 30, 20197 yr Hi. I am trying to get a Windows 10 VM running on a vdisk on my cache drive, and a secondary physical disk. I followed Space Invaders video to do so, and it seems to work fine. but as soon as I read from the disk, the CPU utilization in Unraid rises to 90-100%, which makes the VM and whole system slow down drastically. In the terminal, I can see that most of the CPU utilization is caused by io <wait. %Cpu(s): 11.6 us, 8.6 sy, 0.3 ni, 5.3 id, 73.9 wa, 0.0 hi, 0.4 si, 0.0 st Simultaneously with this issue, my cache drive is heavily loaded in reads, which I don't quite understand. The primary vdisk is located on the cache drive. I have recently run an extended SMART test, without any errors, on the SSD, which is an Intel S3500 300GB drive. The issue goes away when I stop the VM and only starts again when I read files from the SSD again. Bonus info: The task manager inside the VM does not show any significant loads on either CPU, memory, disk or network. My thoughts: Maybe it´s a buffering issue in the primary vdisk? hotbox-diagnostics-20190530-1954.zip
