and when i add the same ip and subnet mask and default gateway that is working normally .
can you help please !
qemu/KVM have no ability to change passwords inside VMs.
Use your physical machine to download the ISO file of PCUnlocker, then mount the ISO file to your virtual CD drive, change the boot order and you can then reset Windows 8 password offline. Of course, you can also use other softwares like Ophcrack.
But it didn't seem to support Windows 7 work , (Local account )I also used UUKeys windows password mate to reset Windows 8 password , it works fine.
