2011-12-06 11:54:27 Michael Tokarev description Applies to both qemu and qemu-kvm 1.0, but only when kernel is 64bit and userspace is 32bit, on x86. Did not happen with previous released versions, such as 0.15. Not all guests triggers this issue - so far, only (32bit) windows 7 guest shows it, but does that quite reliable: first boot of an old guest with new qemu (or qemu-kvm), windows finds a new CPU and suggests rebooting - hit "Reboot" and in a few seconds it will be locked up (including the monitor), with 100% CPU usage. Killable with -9. Only applies to qemu-kvm 1.0, and only when kernel is 64bit and userspace is 32bit, on x86. Did not happen with previous released versions, such as 0.15.
