What is Best, VirtualBox, VMWare or virt-manager

QEMU/KVM all the way. VMware is a dead end now that broadcom owns it imo.

The curious me as usual, I found an appimage for gnome-boxe here https://www.pling.com/find?search=gnome-boxes

This is a good way to try software without really installing.

I really hope this helps!

Really depends on the user and the use case, I have virtualbox just because it is one of the first I discovered and found it easy to use and set up (most of the time)

Same here, virtualbox was the first I discovered and used for long time.

But I see here most users are suggesting virt-manager, I tried it a few days ago and it was ok, seemed better than virtualbox as end user experience.

I will try as well Gnome box (app image).

I will add 32GB RAM, hopefully one chip, (on top of the 8GB I have) to be sure everything will work properly.

I often mean to try out others too, might end up doing so now as its on my mind

I understand for sure.
I am always trying new things all the time.

I wouldn’t use this for at least two reasons: 1) it is not an official release; 2) it is six years old

Oops! My bad! I admit I just posted the link without reading!

Well, so it will be virt-manager then or perhaps install gnome box and uninstall it if I don’t like it.

I will look deeper at gnome box first.

I think Virtualbox is the first name that comes to mind when talking about VMs. I worked with VIrtualbox for a long time before switching to virt-manager. While I cannot say virt-manager has a superior interface, I was an instant convert when I saw the performance difference between a VM running in Virtualbox and the same machine running in qemu/kvm (with virt-manager as GUI). I could not go back to using Virtualbox as I see no reason to leave a huge chunk of performance on the table. By performance i mean mostly the virtual display adapter, which produces smooth, accelerated graphics, making any desktop environment run just like on bare metal. I’m not talking about gaming, just normal DE effects, which in Virtualbox are a bit sluggish. I also like the seamless control transition between guest and OS, the mouse is not held hostage, but switches from guest to host seamlessly, when entering, exiting the area occupied by the guest on screen.

You pinpointed exactly what I noticed when I used virt-manager (though it wasn’t that smooth experience because of only 8GB RAM only 2 GB for the virtual machine). PERFORMANCE and

I noticed this as well.
Though it is not as easy as VirtualBox but it is worth it. It is not difficult though, it just needs some work.

Hopefully I will upgrade my RAM and add 32GB soon.

What about all of that 32GB RAM? What is it for? I think 4GB RAM for VM is enough!

Qemu is the best for me. The KVM thing is really powerfull not to use, while being on linux.

It depends what you are doing in the VM and how many you have running at the same time. There are times when I have more than 32GB of RAM consumed by VMs.

As usual, @dalto always gives the best advice.
I tried gnome-boxes and I loved it.

The only two issues first I don’t know why during installing any os the screen and fonts are too tiny and hard to read…
Second, installing virtual EOS is unfortunately Grub only!

But generally speaking it was ok

I’ll stick with vmware workstation pro which is also now free for personal use.
