Windows VM doesn't boot on QEMU KVM when hypervisor is disabled in Linux 6.12 Description of problem: Windows VM doesn't boot on QEMU KVM when hypervisor is disabled in Linux 6.12. QEMU uses 100% CPU core usage and nothing happens. It boots properly in Linux 6.11.10. I don't know if it's a kernel bug or QEMU needs some changes to work with the new kernel correctly. Steps to reproduce: 1. Boot Windows 10 or 11 (can be installation ISO form official website) with KVM, but set "hypervisor=off" CPU parameter. 2. Wait. 3. Nothing happens - doesn't boot. Additional information: Nothing is displayed in console.
