Which version of QEMU do you use? You can run QEMU with the original (=vdi) image (and use -snapshot, then QEMU won't write to the image), too.
A Windows blue screen or a start menu is a clear indication that the image conversion was successful. Therefore I assume that this is not a QEMU related problem but a Windows problem. Windows does not like when you move installation images from one machine to another one with different hardware. That's what you do when you move from VirtualBox to QEMU. ** Changed in: qemu Status: New => Incomplete -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/907994 Title: converting VDI to IMG Status in QEMU: Incomplete Bug description: I'm so close to moving away from VrtualBox to using Qemu. However I've run into some issues converting my existing virtual machine from VirtualBox to Qemu. I'm running Qemu on Fedora 16. I took my windows_xp.vdi and tried to convert it to qemu. The conversion goes well without any errors but then when I import the converted file to Qemu, it won't start. Here is the info on the file that I'm trying to convert: INFO ===== $ qemu-img info windows_xp.vdi image: windows_xp.vdi file format: vdi virtual size: 21G (22020096000 bytes) disk size: 9.4G cluster_size: 1048576 CONVERT COMMAND ================== qemu-img convert windows_xp.vdi windows_xp.img I created a new virtual machine and used the converted machine created (from the above step). When I try to start the newly created virtual machine, it keeps failing. There is a blue screen of death that goes away too soon. and I'm stuck with the windows start menu "safe mode, start normally " etc.. but no matter what I do I can't seem to start the vm. Any help much appreciated. Thanks To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/907994/+subscriptions
