When I dump the CPU registers via "info registers", nothing changes, that m= eans the system really stalled. Same happens with QEMU 2.0.0 and QEMU 2.1.0. But - when I run the very same guest using Kernel 2.6.32.12 and QEMU 1.7.0 = or 2.0.0 on the host side it works on the Core2Duo. Also the system above but just with= an i3 or i5 CPU it works fine. I already disabled networking and USB for the guest and changed the graphics card - no effect. I assume that some mean bits and bytes have to be set up properly to get the thing running. Seems to be related to a kvm/processor incompatibility. ** Affects: qemu Importance: Undecided Status: New ** Tags: core2duo kvm ** Description changed: When I start up QEMU w/ KVM 1.7.0 on a Core2Duo machine running a vanilla= kernel 3.4.67 or 3.10.12 to run a Windows 8.0 guest, the guest freezes at Window= s 8 boot without any error.
