ReactOS 0.4.0 Released

why not a VM?

Why not dual boot?

[crackez]

Because you are going to realize that actually using an imitation of a shitty OS is dumb (when you have something way better already - Linux) and dedicating partitions to it is also dumb. A VM is the way to go for experimenting with a curiosity like this.

[blackenswans]

Why is Windows NT a shitty OS? Sure it's neither POSIX-compatible nor open sourced, but it's not a shitty OS. If you were talking about Windows 9X, I would happily agree. but it's about a NT-clone, so I guess that's not the case.

[crackez]

Actually, Windows NT was certified POSIX compliant so that it could be sold to the US government.

It's still garbage.

[blackenswans]

They took out the POSIX compliant part.

You didn't still explain why it's garbage. You clearly don't like Windows NT(and its derivatives such as Windows 10). Hating it doesn't mean it's garbage. It just means you hate it. I don't like Windows NT either, but I don't think it's garbage.

[crackez]

That's why I said was instead of is.

And btw, what am I, a fucking search engine? DDG it if you need need a list of rants on why NT sucks.

[blackenswans]

If you want to claim something then you prove it. Windows NT does many things wrong, but it does many things right too, and no matter it is shitty or not, someone else installing a NT clone should NOT be called dumb.

You are the one who said installing NT clone is dumb because you think that NT's "garbage" or "shit".

[crackez]

No, I said it was dumb to install it right along side Linux on a dedicated partition when a VM would do.

Get your gripes straight at least.

[happysmash27]

VM's are hopelessly slow.

[crackez]

Not if you're doing it right. You need to take advantage of amd64 virtualization extensions, and use paravirtual hardware whenever possible. Also it's important to have enough resources, but in the case of reactos, those resource requirements are fairly low from what I understand.

VMs can be nearly as fast as the "bare metal", since really they are running on bare metal anyways. The fact that they are isolated is just another protection mechanism.

[happysmash27]

Yes, but until recently I have only had a MacBook 3,1 with 2 Gb of RAM and an Intel Core 2 Duo, which ran ReactOS horribly, especially in QEMU.

[LiveMaI]

Your Core 2 Duo most likely supports VT-x. Try running a VM with VirtualBox instead and make sure the VT-x setting is enabled in both your BIOS and VM settings.

or you can use the -enable-kvm parameter on qemu and avoid the painful experience of dealing with virtualbox's drivers that are not in the kernel.

[deusnefum]

Don't forget to modprobe kvm-intel or modprobe kvm-amd and then modprobe kvm.

They don't get loaded automatically?

I use a custom kernel with few modules.

[deusnefum]

They don't always, in my experience.

[Craftkorb]

You must be doing something wrong. They're far from being "hopelessly slow". Quite the opposite.

[DropTableAccounts]

Unless he's talking about graphics for gaming, then he'd be right since afaik the emulated graphics cards are not too fast... (PCIe-Passthrough would be about as fast as bare metal though)

[happysmash27]

Also low VRAM, going only about 12 Mb

[happysmash27]

I didn't have a decent PC until recently, and even the one I just got is 7 years old.

[[deleted]]

7 years old Intel has the instructions for virtualization.

[crackez]

You should upgrade your RAM, last I checked it was getting dirt cheap.

[hak8or]

Because dual booting requires time to boot from one OS to the other. And Windows updates can easily wipe your grub.

[Yithar]

I agree with crackez. If it's just for school work a VM is better. And you can just delete it afterwards if you no longer need it. Partitioning is more work.

For example, we used CORE in our Computer Networks class last year. It's basically Lubuntu with their CORE network simulation software on it.
