This clearly isn't the case here. I've checked with vmxcap and my PC indeed does not support unrestricted mode. My Laptop (on which the identical image works perfectly) does. > # rmmod kvm_intel > # modprobe kvm_intel emulate_invalid_guest_state=1 > > Warning: experimental code. Tried it out -- I don't get the error anymore, but qemu just hangs on boot with 100% CPU. :-( >> Or is >> it impossible to run Windows 7 with kvm on a Core Quad (which possibly >> doesn't support "Unrestricted Guest")? > > It should be possible. Did you do anything special with the guest > (install any software?) before rebooting? Is this repeatable? Nothing at all, just a standard installation. Did not even get to the point where I *could* install software (it reboots during the installation and that's where it doesn't come up anymore). I even tried to completing the installation on my laptop (which works), then copy the image back on my desktop PC: Same error. Any hints on how I could debug the hang with the emulation of invalid guest state? Or is there a more recent version (git?) than a 3.3.7 kernel that I should try out?
