Alternative solution/bug is mouse usability in qemu for Linux. Well-known issue of error 0x5D when booting Win 7 x64 on qemu without kvm, marked as resolved at Linux. Used qemu for Windows downloaded from http://qemu.weilnetz.de/ Tested on qemu 2.3.94 64-bit and qemu 2.4.0 32-bit. Options : qemu-system-x86_64.exe -m 1536 -cpu qemu64,+nx,+pae,+mce,+cx8,+apic,+sep,+mtrr,+pge,+mca,+cmov,+pat,+pse36,+clflush,+acpi,+mmx,+fxsr,+sse,+sse2,+ss,+fxsr,+sse,+sse2,+ss,+de,+mtrr,+mca,+clflush win_7_work.qcow2 On qemu at Ubuntu with kvm Win7 x64 works ,but mouse is unusable as mentioned above. A solution is to convert from vmdk to qcow2 and back working in VmWare with Windows images. Repeated Windows activation could be needed. Looking through old bug tickets... can you still reproduce this issue with the latest version of QEMU? Have you tried "-usb -device usb-tablet" already?
