Prevent imediate reboot after blue screen

[frantek]

Hi,

I know that there is a trick to prevent a KVM VM from rebooting imediately after a blue screen. But I don't remember how. I know how to do this in Windows but this is no option as it does not boot at alle. How can I tell Quemu not to reboot imediately? I want to see the bluescreen

TIA
Matthias
