Are you using -snapshot? No, not using -snapshot anywhere. I'm not sure how much detail you want, but here's from the beginning: #qemu-img create -f qcow2 vista 20G #qemu-system-x86_64 -m 2048 -cdrom vistasp1.iso vista [install vista without updating and exit] #qemu-img create -f qcow2 -b vista vista.delta #qemu-system-x86_64 -m 2048 vista.delta [update vista with all the recent patches and exit] Everything above works perfectly. I can reboot vista, check for new updates, create user accounts, all the normal stuff. Now comes the trouble: #qemu-img commit vista.delta [takes >1 hour] Now, IIUC the base image vista should be entirely useable by itself, i.e. I can delete vista.delta and everyting should still work correctly? But it doesn't. For example, when I boot vista and try to look for windows updates, the updates page is almost blank and completely non-functional. There may be other problems too, but I haven't bothered to look. BTW, I've been through the same steps twice and get the same results, so I don't think it's flakey hardware. OTOH today is a new day, so I'll try it again to triple check. Any thoughts?
