It doesn't have to be very big (8 MB will do) and you don't have to format it. 2. Start the Windows VM and add this second hard drive to the VM: qemu-system-x86_64 -m 256 -hda hda.img \ -drive file=3Dnew.img,if=3Dscsi,bus=3D0,index=3D0,media=3Ddisk,boot=3D= off ... At this point, Windows should start, find the new drive, and install all the drivers for it. 3. Shut down the VM. This time, don't include the new temporary image = from step 1 and define your disk(s) as SCSI disks: qemu-system-x86_64 -m 256 \ -drive file=3Dhda.img,if=3Dscsi,bus=3D0,index=3D0,media=3Ddisk,boot=3D= off ... At this point, the Windows VM should boot from the SCSI drive without a blue screen. Verify that the drive is now a SCSI disk by going to the Device Manager and making sure the model of the hard drive includes the word SCSI. That's it. If anyone can attest to this procedures and report, it would = be greatly appreciated. Along those lines, if anyone knows how to grab an existing Windows VM = that was set up in VMware and make it run in Qemu (KVM), I would = really, really appreciate it. Everytime I try I get blue screens. :-( -- = Alberto Trevi=F1o alberto@byu.edu ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference = Don't miss this year's exciting event.
