Looks like the USB mode was the issue for me. Changing USB controller to USB 2 or USB 3.0 (nec XHCI) seems to have fixed it.

Likewise I had Windows 10 installed and now it rarely starts. I have just tried to create a new Win10 VM in case my previous one corrupted but no luck, it keeps dying on me. I'm on 6.9.2 and have made the Tips and Tweaks change to Performance and Turbo enabled. All my cores end up reaching 100% even if I only allocated one or two, then the VM dies. EDIT: Ubuntu 20.04 VM is fine, just the Win10 one that won't work

I'm new to Unraid and it took me a while to get it going, here's my setup if others need help and a thanks to those who have posted on here, I wouldn't have had it working without it: Setup: Unraid v6.9.0 2021-02-27 (vs -rc2) Motherboard Gigabyte B460M DS3H rev 1 - (this only uses UEFI) Intel 10400 16GB Ram Advice followed: Space Invader One's guides to setting up Windows 10 VM parts 1 and 2 (although 2 focuses on separate graphics card) Picha's post on a similar setup and the previous advice in the post VM: Initial Memory: 10 gb Machine: i440fx-5.1 BIOS: SeaBIOS Hyper-V: Yes Graphics Card: Intel UHD Graphics 630 Graphics ROM BIOS: vbios_gvt_uefi.rom I kept getting the black screen and when I tried using VNC after some (unknown) changes I had a bit of mouse lag where the pointer was not as expected. The key difference to above is that after I could log into VNC I went onto the Gigabyte website and downloaded the video and audio drivers for Windows. After an install and reboot it worked fine. Sharing this in case it helps others.
