So I write this email. I'm trying to run an existing windows xp (32 bit) partition in qemu on a x86 64 bit linux host. I always got A disk read error occurred Press Ctrl+Alt+Del to restart when qemu starts. There is no problem to run an existing windows xp in qemu on a x86 32 bit linux host. There is no problem to install and run windows xp in qemu from a disk image file on x86 64 bit linux host. Interestingly, I tried KVM and Virtualbox. I got the same error message for both of them. Since both KVM and Virtualbox use some modules from qemu, I guess the root cause is in qemu. So I first report this bug here. Regards, Jie
