Other than having a nice management UI, what does Virtualbox do that qemu doesn't these days?
replyRun your years-old VirtualBox images? If I were to guess; maybe QEMU does that too.
replyThe qemu-img(1) installed on my system claims that it supports every disk format supported by Virtualbox [0], so I guess the only thing left would be to be able to handle the "machine definition" file.
replyqemu definitely won't do that out of the box, so, yeah, VirtualBox is better than qemu there. But I bet there's a fancy-pants GUI out there that has an import wizard that will handle that for you.
