VM config:

16 GB RAM (ballooning is off)
1x GTX 1660 Super GPU PCI Passthrough
OS- windows 10

When I am starting VM, Sometimes it timeouts with following message

Code:

When I reduce the RAM to 8GB the VM Boots fine. I have almost 70 GB RAM Free on my server, still why is this happening? Any ideas?
