That's not the point here. Can you roll back changes? Can you make a snapshop of one system and then revert to it? Can you duplicate a system and send it to someone? Can you keep backups of just one system? Can you store backups on a server or a removable drive? All those are trivially easy with VMs. > As are QEMU Can with hardware assist run native code, but that is harder. Works with KVM on Linux to do it, but also harder. > BOCHS Not the same thing.

These are not the same sort of tool as the 2 I mentioned, which I picked for good reasons. They are true hypervisors, they run real unmodified OSes at full native speed, and they do not not require any particular host OS. > All the VM's have advantages and disadvantages in various respects. 3 of the things you mentioned are not VMs. This makes me suspect that perhaps you are not as familiar with this tech as you think you are, and I urge you to at least evaluate it. > In addition to the VMs mentioned above, I also have others including VMWare > and DOSBox and do tests with all of them.

I am not saying there isn't. I am saying that there are easier ways than a tool you happen to know well and be familiar with. I am not telling you you're wrong or anything, just suggesting something to make life easier. -- Liam Proven ~ Profile: https://about.me/liamproven Email: lpro...@cix.co.uk ~ gMail/gTalk/FB: lpro...@gmail.com Twitter/LinkedIn: lproven ~ Skype: liamproven UK: (+44) 7939-087884 ~ Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053 _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
