I am running:

TR 1920x

Gigabyte x399 Auros Pro

4x8GB DDR4 3600, (checked on QVL)

2 x 1TB WD Blue NVME  - Disk 1 and 2

2 x 1TB WD Blue mechanical drives - Parity Array

2 x 480GB Sata SSD - Cheap brand - Cache

ATI 7570 - Primary display

Nvidia GTX 980 - VM1

Radeon RX 580 - VM2

 

2 x Win10 VM's with 8 logical cores each and 8GB Ram

Install of windows takes several hours, updates take even longer, I am at a loss to explain what is going on, if anyone can offer any explanation/solution it would be awesome!

Your vdisk share (presumably where you've got the vdisk mounted for the VM) exists on the cache drive and on disk 1 / 2.  On which drive is the vdisk for the VM actually stored?  On the array will have a huge performance impact.

 

 

so I had problems with the cache, unraid wouldn't allow me to mount both SSD to one cache pool, hence I created two cache pools with one disk each. I tried storing the VM's on the Cache, but kept getting a message of no UUID.

Anyhow I have created a new pool with the two NVME drives. now the VM's install WIn10 at reasonable speed, however the second VM crashed after I update the net driver, and proceed to run updates, it goes into black screen, I have restarted the VM and it gets stuck starting up, and eventually goes into repair, which doesn't work either.

I have reinstalled Win10 several times now and each time as soon the network card driver is added shortly after it crashes and I notice some very strange behavior on the dashboard, with different cores randomly hitting 100% for half second then going to zero then a different core hits 100% and back down and so on until I kill the VM
