i have been messing around and had issues with the Windows 10 VM not booting and crashing.... traced the fault to using e1000-82545em as the network adapter choice in Windows 10 VM XML file.... when it was set to virtio Windows 10 booted every single time no issues using Q35 3.0 / 3.1 so i just passed through the entire nic through to the VM Intel 1211AT no problems now
so the system passes the wife test
Turn it on and it works finally 😛
